Hyundai - Elantra :: 2004 - Relatively High RPMs When Accelerating With Sluggish Acceleration?
,I have a 2004 Hyundai Elantra (stick shift) with about 104k on it. Was running absolutely great till about a month ago when I noticed that it was beginning to accelerate quite slowly. If I pushed it and got the RPMs up really high it would still pick up, but still not great performance. Also after pushing it a little hard there was a faint burning or smoke smell. Note, once it is up to speed say 60 or 70 it has no trouble maintaining such speeds. It just takes a while getting up to them. And if I really need to step on it the RPMs sky rocket with no real immediate increase in speed.

I've got an 04' F150 and the ONLY problem I have with it is a ridiculously sluggish throttle. I bought the Superchips Tuner in hopes of eliminating this, but the delay in the throttle is still there (power is much better however). When I talk delay, I am talking hitting the gas and probably a realistic .5-1 sec delay. It is quite annoying to say the least.
My question...is there something that I can do myself to improve the throttle response? I drove an older 150..probably an 02 or 03 and it felt sooooo much more powerful just do to the throttle. I am even willing to ditch the Superchips if the Ford re-tune would do a better job.
Ford F-150 (2004-2008) :: Acceleration Seems Sluggish When Getting On The Interstate
2007 F150 King Ranche 4wd 5.4 192000 miles.
I started noticing a little stutter when trying to hold 45 mph if I hit a mild incline, and also at 70 or so if i hit an incline.
Around the same time, I noticed that acceleration seemed sluggish when getting on the interstate. Gas mileage dropped from 16-17 mpg combined to 12-13 mpg combined.
Historically, since I bought the truck 3 years ago, if I go WOT to get up to highway speed (Not my normal mode of driving, more of a test) I would get a misfire on cylinder 8.
About 2 weeks ago, driving around town, I got a check engine light. The code said it was rich on bank 2. Cleared the code, it has not come back.
Here is what I have done:
Flushed the tranny (Vehicle history shows this has been done consistently since original purchase)
Changed all 8 plugs (none broke!) and all 8 COPs. - Fixed the misfire on cylinder 8.
Still sluggish and still have the stutter at 45 and 70 on an incline. I know it's not a racecar, but 0-60 in 19.6 seconds seems quite unreasonable.
New Fuel Filter
New Air filter
Cleaned MAF sensor
Had the back pressure on exhaust checked. No blockage there.
My torque app tells me the TPS is functioning normally.
No codes are being thrown, no CEL at this time.
What am I missing? I have a reader that will chart up to 8 sensors as I drive.
Passat (B6) :: 2008 - CEL Came On Then Went Away - Acceleration Is Sluggish
Well, I just went to grab some lunch and on the way home I got on it a bit. I was met with sluggish acceleration and a flashing CEL. Before I could even turn the car off, the CEL went away. I was about 200 yards from my house so I coasted home. What could the issue be?

Ford 7.3L Power Stroke (1999-2003) :: Fuel Pump Runs For 20 Seconds At Key On / Long Start Takes About 6 Seconds
This applies to a 2001 F-350 with 73,000 miles on the engine. Engine oil level is good, batteries charged, HPOP reservoir is full and passes Cody test with flying colors. Fuel pump runs for 20 seconds at key on. Start takes about 6 seconds. If I shut the key off and restart immediately it starts in under 2 seconds but if I wait about 30 seconds it's a 6 second start. Here is an AE that I ran on it, it has me stumped. FWIW it seems to start quicker when AE is hooked up. ?? An odd whir type of noise comes out from somewhere under the hood when I first turn the key on and when I clear the codes with AE.

I bought my 2004 RX 330 last year with 110k miles. It starts up every time with no problem, except that It takes a few more seconds to turn over the engine till it starts. I have to keep the key turned longer that my other cars where all I need to do is just turn to start for a second only. I just replaced the battery and that did not change anything.
Is this normal for my RX 330, could I need new spark plugs? It's never been a problem in winter or summer.
Prius (2004-09) :: Loses Power In Heat - Sluggish Acceleration
I have a 2004 Prius, ~150k miles. At about 80k I replaced the inverter coolant pump as a preventative measure.
Recently, the car has shown an intermittent lack of power, and abnormally sluggish acceleration, which seems similar to what I've heard about the failsafe mode of an overheating inverter, except no warning lights appear. We have had some hot days this summer in SLC, Utah (100+ deg). It's a sporatic issue that seems much worse on hot days. The weather has been hot, but we've had hot days in past years and not had this problem.
Yesterday, the car showed the worst ever such behavior and was nearly crippled for my wife (why do these things always happen when the wife is driving alone?). She was returning home from a ~ 1hr appointment, where the car was parked in the sun, ambient air temp was ~103 deg. The car was very sluggish and ICE was revving much higher than normal. The battery fan that vents next to the rear passenger-side door was running at the higher speed than she's ever heard it before. I asked her at the time about the battery level, and the display showed two bars, even though she was going mostly downhill. A/C seemed to be working, but she turned it off. She was able to limp home. It did seem that when the battery charged a bit, performance improved somewhat.
After I got home a few hours later that evening, (temp ~90-95 deg), I took it for a spin and it seemed fine. I'm pretty sure I detected a slight hiccup in power one of the times I punched it, but nothing drastic. She drove it this morning (84 deg ambient, ~75 deg overnight low) and it seemed normal, except that she could hear the battery fan (we almost never hear it running), but it was much slower than yesterday.
Santa FE SM (2001-06) :: 2004 2.7L V6 2WD - Codes For Sputtering / Sluggish Acceleration
2004 Santa Fe 2.7L V6 2WD ... Car was running fine, filled it with gas, and upon starting, heard a backfire into the intake manifold. It coded for a Cylinder 3 misfire so I had plugs and wires changed.
Now...The car starts, idles rough, accelerates sluggishly, and running rough any time it was around 2000 RPM. After I changed the plugs, it started bucking a little and stalls when I take off in the morning.
Coded and it's reading 7 codes, but some are duplicates:
-P0274 Cylinder 5 Injector Control High
-P0305 Cylinder 5 Misfire
-P0102 MAF or VAF A Circuit Low Input
-P0050 H02S Bank 2 Sen 1 Heater Circuit
-P0030 HO2S Bank 1 Sen 1 Heater Circuit
-P0274 Cylinder 5 Injector Control High (Shows Twice)
-P0102 MAF or VAF A Circuit Low Input (Shows Twice)
After having a backfire and then cylinder misfire...replacing the plugs and wires.
Mazda - Mazda6 :: 2004 - Burning Oil Smell And Sluggish Acceleration
Car Details : 2004 Mazda 6 V6 3.0 L engine automatic transmission with 88,000 miles
Car Problem Vignette : After driving for a bit, say 20-30 mins (after my engine gets hot), I start to smell a burning oil smell. I’ve looked under the hood at my engine and do notice some oil leaking from the engine. This is not just some simple oil leaking after an oil change. The oil appears to be coming out of the engine "seams" itself. This has persisted for some time now. This problem started at least a year and a half ago now (12/05/12). I’ve had a mechanic take a look at the oil leak and supposedly he fixed the head gasket or valve cover gasket (I’m not sure which one), but the problem never fully resolved.
In a related or unrelated situation (I’m not sure yet if it is related) during this time my car started to jerk and sputter when I drove, so much so that I wasn’t sure it was going to make it to work one morning. The check engine light came on and I eventually made it to work and back home that day. It gave me a code that said one of my cylinders was misfiring. I proceeded to change all of my spark plugs to no avail. I then changed out one of my ignition coils to the bad cylinder misfire. It fixed my problems with the stuttering and I could drive my car again without fear of stalling. However, I still smelled burning oil. Over time I eventually started to feel my car struggle to take off during acceleration which felt different from when my car seemed like it was going to jerk and sputter to a stall. During this time frame one day I was at a stop light and when I went to take off, a huge plume of bluish / white smoke came out the exhaust and I smoke-screened the people behind me. After that incident, I ended up changing my positive crankcase valve (PCV). After changing my PCV my car felt like brand-new again! I could not believe it! My car started accelerating smoothly and driving so much better. I felt like I had gotten the “Zoom Zoom” back for my Mazda.
Sadly this didn’t last long, maybe a month at the most. My car started struggling during acceleration again and I started smelling burning oil again. I have dealt with this for over a year now. My car still runs and gets me around, but I can’t remember the last time that my car ran smoothly or didn’t smell like burning oil except for that time I changed the PCV. I have never seen any kind of smoke coming out of my exhaust again like that one experience.
Problems:
•Burning oil smell coming from my engine due to leaking oil coming out the "seams" of the engine
•Car is struggling when accelerating especially at lower gears
•I feel it every so often when I accelerate somewhere between 2nd and 3rd gear that the car jerks and makes this “chunk” type sound and feeling when it shifts gears.
Questions:What is wrong with my car? Are all these situations related? And what do I need to do to stop the oil leak and acceleration problem?
Ford F-150 (2004-2008) :: 2006 FX4 5.4L Takes About 10 Cranks Before Firing Up
Recently my F150 has had issues starting in the mornings. It is in an insulated garage. It takes about 10 cranks before it fires. Then it struggles to run like its not getting fuel for a second or two, then rpm's jump to 1200 and has a slight miss for another second or two, then it smooths out and is fine. Leaving my driveway it will have a miss around 2000rpm for about two seconds then the truck will run perfect the rest of the day. It can sit outside in the cold for 10 hours while i am at work and will fire right up and run great. The issues only happens in the morning.
All the plugs were changed about 6 months ago. Fuel pump and fuel pump drive module were changed about 3 weeks ago. The check engine light has come on twice. The first time I didn't have access to a code reader and since the truck started right away and then died instantly i figured that was why the light came on, so i disconnected the battery and re-connected it. Light didn't come back on for a week. Second time code was for misfire on cylinder 5. I am changing the fuel filter this week. If that doesn't work i was gonna change the #5 coil.
Ford F-150 (2004-2008) :: Engine Takes Two To Three Attempts To Actually Start - FDCM Symptoms?
Very occasionally my 4.6 doesn't seem to be getting fuel when I crank it. On those occasions the starter cranks the engine fine, but it takes two or three attempts to actually start. 64K on the truck, and the fuel filter was changed about 10K ago, throttle body cleaned at the same time. Does this sound like a FDCM issue?
View 2 RepliesFord F-150 (2004-2008) :: Truck Shuddered / Lost Speed And Incredibly Sluggish Trying To Get Uphill
My truck decided to have some issues last weekend coming home from a friends house. After being on the road for about an hour the truck shuddered, lost speed and was incredibly sluggish trying to get up the hill. It flashed the CEL and then went out. I was doing about 75 with the cruise on.
After slowing down to about 60 it stopped the shuddering and resumed operations as normal. Until about 20 minutes later when it repeated the above.
The next day I grabbed my reader and found the P0302 and P0306 codes. I cleared the codes and took it for a "test" drive up and down the mountain to see if it would trip the codes again. It didn't flip the codes. I thought I might have been dealing with a "one off" issue and left it alone for a few days.
Two days ago the CEL light came on and stayed on this time. Sure enough P0306. Cylinder 2 did not throw a code this time. After doing some research on here I ordered two new COPs and bought a mechanics stethoscope and some new spark plugs just in case.
The stethoscope confirms that cylinder 6 is having some issues. The COPs came in today so I'll take it apart tomorrow and see what I see. I'll be looking at both the COPs and the plugs to see what may be causing the problem. The "nice" thing about this is that at least it's one of the easier COPs to get to.
Should be a nice day for working on the truck.
Ford F-150 - 1997-2003 :: Cranks But Takes 10 - 15 Seconds To Start?
It driving me crazy. Every 10th start of engine it cranks over and over before it fires up, no codes, changed plugs, wires, crank trigger, fuel filter, upper and lower intake gaskets, injectors, iacv. I have no clue. Runs great all time just starting issue every 10th or so start takes 10- 15 seconds to start
View 2 RepliesFord Escape / Hybrid :: 2006 - Hard To Start Now Takes Between 3 To 8 Seconds To Actually Fire
Wifes Escape with the 3.0 has been progressively getting harder to start. It spins over just fine, but now takes between 3 to 8 seconds to actually fire. In the last six months the alternator, spark plugs, air filter have all been replaced. Engine runs perfectly, never stalls and seems fine in every other way. I've cleaned the throttle body and the IAC is working fine.
Did some troubleshooting and sure enough, we are getting no spark for a few seconds and the engine runs fine when it finally gets spark. Would this be the crank position sensor? Cam position sensor causing this? Not sure what is supposed to happen during the starting sequence in regards to what sensors are in being read by the PCM and then enabling spark.
Ford 6.0L Power Stroke Diesel :: New Injectors - Now Truck Takes Almost Two Seconds Of Cranking To Start Engine
I just finished installing a new set of injectors, standpipes and the blue spring kit on our 2005 Excursion 6.0. The truck idles and runs much better but now it takes almost two seconds of cranking to start the engine. Cold and hot are the same and the length of time between shut down and start doesn't seem to matter either.
What to check? I am planning to check the ICP tonight when I get home. Could I have air trapped some where in the system? This is my first powerstroke so I don't know if this is a possibility.
Ford F-150 (2009-2014) :: 2013 - Transmission Downshifting At Odd Times / Truck Takes A Few Seconds To Accelerate
I have notice maybe a dozen times in the last few weeks that my 2013 5.0 Screw downshifts at odd times. It usually occurs while coasting around 35-40 mph (in 4th gear and downshifts to 2nd gear) or around 50 mph (in 5th gear and downshifts to 3rd gear). Obviously when this occurs, the rpms jump and when I get into the gas, the truck takes a few seconds to accelerate because it first must shift into the next higher gear. What is causing this?
View 2 RepliesFord 6.0L Power Stroke Diesel :: Acceleration Is Also Getting A Bit Sluggish Especially Going Uphill
What is a "normal" number people see on their load factor? Mine was around 25-30 a few weeks ago but I noticed it is increasing to around 30-40 once I'm in gear, in park it's fine. My acceleration is also getting a bit sluggish too especially going up hills and my throttle isn't responding all the way, my turbo boost is normal though and I don't think there is any VGT stiction. I'm thinking either a fuel filter or a MAF sensor to start with. Fuel filters have been in exactly 10 months. Can a dirty fuel filter, air filter, or MAF sensor affect engine load at idle and how fast it accelerates? I feel like I'm pulling a trailer and with it being more sluggish, my transmission is shifting harder as well.

I have a 2006 F250 Lariat super Duty / 6.0 L engine / 143000+ miles / once started and transmission shifted into drive it takes 5 seconds or more for it to engage hard or if I build up the RMS then it jumps into gear hard, after it gets going it feels like I am driving on a washboard until it get warmed up good 10 mile or so. Is it the transmission filter and if so which one, I understand there is a small one on the outside of the transmission if so where? I can't find it.

When I start my truck it takes 30 seconds or so for the truck to start moving... especially when in reverse. If I give it some gas it doesn't take quite as long. I am not a transmission guy. I assume it has something to do with building pressure but I don't know what would be the cause. The fluid is full and looks good.
