Dodge - W150 :: Engine Stumbling / Partial Throttle But Only When Warmed Up
About two weeks ago i had a ton of work done to my W100: clutch, freeze plugs, valve seals, body mount bushing, headers, x-pipe dual exhaust. The shop did tell me before i picked it up that it had a lean pop and the carb needs to be rebuilt.
as of now, it idles fine and drive fine when cold, as it starts to warm up it starts to become problematic - it feels like the engine stumbles any time you try to maintain a constant speed (slight throttle engagement), it accelerates fine, but that's about it. You have to drive it in a constant state of accelerate and foot off gas because it does not like you foot on the gas pedal just a little. if you do keep your foot slightly engaged it will stumble and the exhaust will pop - not so much a backfire as there's not at jerking.
-both coolant sensors are new
-spark plugs are FSM spec champion copper 404/rn12yc
-plug wires are a year old (msd cheaper line)
-timing seems fine (around 8-10 BTDC)
-watched at night to try to see if any arcing was happening, none that i could see or hear
-finagled some exhaust restrictors on the exhaust tips out of rubber plumbing couplers and big lag bolt washers to try to recreate the backpressure from the old exhaust, no difference
-went around the vacuum lines with carb cleaner and propane, couldn't find any distinguishable leaks
Fuel filter about a year old- new fuel pump installed while at shop.
Accent LC (2000-05) :: Bogs Down When Under Load Between 2700 - 2900 RPM
2002 Hyundia Accent -- 1.6 DOHC 2D
When I get to 2700-2900 RPM Under load my car will chug out (basically lose power all together for a brief second) then it will come back and chug out again. I am able to max out RPM's while doing this however under load it still chugs along. WHEN not under load it rev's up fine and purr's like a kitten.
So I went and got a new motor for this car same model as was in the car before a 1.6 DOHC. However upon replacing it (also attached still was the timing belt and clutch assembly, never taken off)
So it seems to be getting spark just fine. and I replaced the MAP sensor thinking it was a intake issue however still problem exists when I am under load between 2700 - 2900 RPM it bogs out for a second losing all power.
Accent LC (2000-05) :: Bogs Down And Bangs A Little Rough When Give A Little More Gas At Stop Light
I have a new problem that I only discovered a few days ago. As I come to a stop at a traffic light, turning out of somewhere or whatever if I give the car a little more gas than normal not that I punch it or anything from a stop the car bogs down and bangs a little rough like I was rear ended. The car is in drive when it happens. Its just fine any other time. I was told it could be as simple as a bad tps or as bad as a defective torque converter or tranny. Its a 2005 gls hatchback with the 1.8L. also, the engine has been running a little rough recently too if that could have anything to do with it. No warning lights are on either.

I have a 2000 Accent that wont shift past third gear until the car is warm. The car has 140k miles. When I turn on the car and pull onto the high way it sticks in 3rd. I then have to slow down and drive through a small town. When I get on the other side of the small town and get back up to speed it will shift. Over drive is on.

View 1 RepliesAccent LC (2000-05) :: Oil Pressure Light Occasionally Flicker At Idle / Car Will Not Rev Past 5k
I picked up an 02' accent, 1.5l that i've been intending to use as a commuter car. Drove fairly well on the way back home, but it seems it's got some low oil pressure issues once it's good an hot. As the oil pressure light will occasionally flicker at idle, mind you the car is near dying too.
Or so I thought, it was also misfiring/stumbling fairly badly,
Pulled all connections, cleaned, dielectric grease on them, fixed some of it. And it turns out the fellow who did the timing belt last didn't exactly remember to put the bolts back on the fuel rail.... Okay, that's fixed now.
Put in a little heavier oil, and no more issues with the light coming on, but I do have some lifter noise it seems like.
As well, the car will not rev past 5k in neutral or under load. Air filter is new, and no obstructions through to the intake manifold.
I'd guess based on the missing bolts here and there, the guy was a bit of a hackjob mechanic and i'm guessing has the belt out a tooth or so.... I can't see anywhere to stick a timing light on to verify ignition timing, how to check the timing belt is straight up? It's a bit of a dog compared to the other accent i've been in. The power band is like 2000-3500 and it just won't climb anywhere past that.
Golf IV / Jetta IV :: Hesitation At Partial Throttle In 1st And 2nd?
Car is a 20th, 1.8t 6-speed.
I noticed something the other day that is happening occasionally on acceleration. At partial throttle, usually pulling away from a light or stop sign, I get this weird hesitation. It only happens at partial throttle and usually only in first, sometimes in second. As the RPMs increase up to around 3k, it's as if I lose power for a second. You can feel the car stop accelerating for a second, then it begins to pull again.
If it's under heavy acceleration it never happens. It doesn't feel like the clutch slipping, more like the motor hesitating, but there's no noises or missing or anything like that. The RPMs don't jump up or anything. It's like for a second it's making no power, then it comes back.
GTI 337/20th Anniversary :: Partial Throttle / Surging Usually In 2nd Gear
I've noticed this when driving for a while now but was never really sure what was causing it. It was usually in 2nd gear and the car would sorta surge on and off boost almost. yesterday i found out that it only occurred when i gave my car partial throttle. It would build boost, let off, build again etc. Full throttle and it was not a problem at all. My car is an 04.5 GLI chipped / 3" exhaust etc etc and would like to know what I can do with this problem.

View 2 RepliesAccent RB (2012+) :: Engine Bogs Down When Downshifts To 2nd Gear At Around 25 MPH
When I first got my Accent a few weeks a go I thought this car just had unique braking functions with the ABS valve, but after driving it every day for a few weeks I think that perhaps the problem is the way the car downshifts.
Whenever I am braking and the car downshifts to 2nd gear at around 25MPH I feel the engine bog down, almost as if you were downshifting at too high of an RPM. However it only happens if I am braking slowly, when I need to brake harder I don't seem to notice it, either because it doesn't do it or because I can't feel it over the more pronounced forward momentum.
I verified that it does seem to be the engine or transmission, because if I brake with the car in neutral it won't do it. So my question would be is this just a normal function of this car, or should I take it in to be checked out?
Accent RB (2012+) :: 2013 - Engine Detonation / Bogs And Surges
Bought a 2013, had been in a flood, couldn't see any sign anywhere of water level or damage, had 12,400 miles and noticed engine ping/detonation when engine lugs, have changed to mid grade and that works but every time I go back to 87 octane it starts back up.....also, I have noticed a bog down of the engine when I just barely give it any gas and if I keep the accelerator in that exact same spot, it eventually jumps into like a surge...
View 5 RepliesFord F-150 (2004-2008) :: 2005 Truck At Partial Throttle Will Shake When Going Up Slight Incline
.Here is a run down of my truck 05 5.4L Screw has 130K on it. Sometime when going up a slight incline the truck at partial throttle will shake very very little. if I put my foot into it the shake goes away and the truck response just fine. It only does this when going uphill on the freeway and on the streets here in Dallas that have slight inclines.
The truck is not throwing any codes nor does it stall at lights. Starts right up in the morning and runs good. Nothing done to the truck except I have an Edge programmer and Magnaflow exhaust. I have pulled the programmer off and returned the truck to stock and it still does the same thing.
I bought the truck used in 07 had 40K miles on it. I'm thinking spark plugs or maybe a coil is going bad. But this doesn't happen all the time just here and there.
Ford Transmission :: 2000 F250 Engine Bogs Down In Reverse And 1st
So last weekend I installed a transgo kit for my 4R100 transmission in my 2000 F250 diesel. I didn't really care about getting a shift kit, but I had problems with delayed shifts and figured the accumulator springs had broken. It turns out that was correct, the 2nd gear spring came out in 8 pieces.
Anyway, the transmission shifts great now, but when I put it in reverse it the engine jumps up 200 rpm and then it bogs down as it engages reverse forcefully. It also does this while selecting 1st from Park.
From what I'm reading it's the TC not unlocking and/or a fluid pressure/volume issue. I've also read the filter might have fallen off, I had a hell of a time keeping it in place. I've checked the the fluid level and everything is good there. My question is when I drop the pan, aside from the filter, what should I look for?
Golf IV R32 :: Car Bogs Down On Throttle
With normal driving or semi spirited, once i change gears the car seems to bog down initially then pick up slowly but then it seems fine, but if I am actually getting on it threw the gears it doesn't seem to happen. its very noticeable sense the throttle response is now and it used to be great. If I let off the gas then get back on it at a lower rpm it seems to happen as well. it just feels like it dips down then picks up. i first noticed it when i down shifted to 5th the car seemed to hiccup and then went on, now its seems to be in every gear, I am not getting any codes or lights what so ever and the car drives fine other than that....
Mods: C2 flash, eip exhaust, intake.
Ford Super Duty (1999-2016) :: 2000 - When AV Engages At Idle The Engine Bogs Down
I am having an issue with a Ford f250, 5.4L, granted this problem existed before and after new A/C compressor, dryer, evaporator, vent door switch, blower motor resistor, new evac and recharge, good pressures no leaks.........Now my problem is the truck runs perfect but when the ac engages at idle the engine bogs down and it seems the clutch is constantly engaging and disengaging........AC blows cold, no issues there, does this sound like an IAC valve problem????
View 2 RepliesAccent LC (2000-05) :: How To Reset A Throttle Position Sensor
I was reading the car's settings using the Torque app and an OBDII bluetooth dongle and I realize that at WOT the ECU is only seeing 85% from the TPS. O know on some vehicles there is an actual procedure like turn the key forward, hold the gas pedal at WOT, turn the key all the way forward w/o starting while pulling the turn signal stalk down or something crazy like that to force the ECU to re-measure while you keep the gas pedal pinned to the floor. I know on other cars when it doesn't read a full 100% you miss out on a small amount of power and MPG so if it's an easy procedure with these cars I'd like to reset it. I did some searching but mostly came up with info on how to replace it and a few related subjects but noting on this specifically for this car specifically.

1986 Ranger 2.3 inline 4
I just recently bought an 86 Ranger from a friend. It had recently stopped working and had no desire to fix it. So here I am. The truck will sit in park and rev all day long, once its in drive it idols fine and moves its self down the street. The problem occurs when I apply throttle. It begins to bog down and I cannot get past 20mph. I have replaced the fuel regulator and also I took the tank down and replaced the fuel pump. The fuel filter is two months old, and the throttle response sensor is two weeks old.
