Ford - Explorer :: 2003 4X4 - Very Rough Idle - Stalling If Let Off The Gas
Bought a used 2003 Explorer 4X4 that runs like crap.... All I know is it has new upper and lower radiator hoses, new battery, new brakes, 2 new tires and new belts... suspension seems great and body is nice too. It obviously needed a new radiator and complete exhaust, so I did those. Now it is running better ( I can actually get the RPMs over 1500) but still running rough and will stall if I let off the gas. It will surge and dip in RPMs. Very suspicious of vacuum leak.
Unplugged the MAFS and it roared upon start but within a minute started the sputtering etc. Currently pulled the IAC and check continuity between pins and it was 10 ohms so that passed but there is no continuity between either pin and the case. So this seems to indicate I need to replace the IAC which I will do tomorrow. I would love to find a diagram that displays the vacuum system so I can make a thorough check of it. Also seems to have an oil leak on drivers side valve cover gasket.
Ford Ranger / B-Series :: 2003 XLT 4.0 Stalling At Stops / Low Idle
My 2003 ranger xlt 4.0 has a stalling problem. The engine light came on in aug and I had it coded at AutoZ and there was a code for the oxy sensor, changed that and didn't work so I took it back. In oct I had it coded and it said the air int temp sensor which i was informed was part of the mas airflow sensor, changed that the beginning of nov, got the computer to reset and it still didn't fix it.
Took that part back and had it coded again a few days later and several codes came up AutoZ code 1732 and the the OEM number to cross for them were: P2195 , P0300 , P0316 , P0174 , P0171 , P2197 . Reset the comp yesterday and as soon as the light came on had them code it again and it came up AutoZ code 1732 OEM # to cross P2195. I guess my next step will be to take it to the dealers to get diagnosed..
Dodge - Stratus :: 2003 2.7L - Stalling At Idle / Engine Suddenly Drops RPM When Hot
I have a 2.7L flex fuel Dodge Stratus with 120K+ miles on it and a problem local mechanics and the Dodge dealership cannot seem to locate. When the engine is hot, and only when it's hot, the car will jerk suddenly while driving for a split second, then resume normal operations. It feels almost like you hit something and is scaring the bejeesus out of my wife. It also sometimes stalls out when at a light after sitting at idle for a few seconds. It idles down from 600 RPM like the air conditioning compressor is cutting on and then dies completely.
The car shows no error codes and the check engine light does not come on when this happens. I have replaced the spark plugs, and the transmission solenoid, which is what the Dodge dealer said "fixed" the car for almost $900, and it did it again on the way home from the dealership. My next idea was to change the fuel filter, or maybe the cam position sensor or timing belt or chain. I wonder if I am just trowing money down a hole at this point though, since Kelly Blue Book on this car is under 2K anyway.
Elantra XD (2001-06) :: 2003 - Stalling / Loss Of Power When Idle And Press The Gas To Go
I got a problem with my 03 elantra, recently the car had a problem of stalling. I replaced the crank shaft sensor and that fix the problem, but the car always when idle and then press the gas to go feels like it has no power at all then all the sudden all power kicks in it only does that for a second when i press the gas. What I did was to replace the fuel filter that actually was extremely dirty,but no change i guess it could be the fuel pressure regulator.

2003 Limited with 4.6, 89K miles. Just started doing this last night. Checked codes, had the DPFE one pop up. Replaced that, no luck. Cleaned the IAC, MAF, throttle body, EGR, PCV, no luck. Used carb cleaner and sprayed around intake & vacuum hoses, no luck there. Checked vacuum, steady 20in even when it lopes. Battery unhooked for 15 minutes. It hovers around 300-400rpm's, sometimes will stall but drives fine. Tested the IAC and it is functioning normally. Nothing above has worked.

A couple weeks ago my 01 7.3 with 265,xxx started ideling rough and stalling. I had driven in all day Sunday and the next day it started out of the blue! It would barely start idle rough and stall out no CEL. I have singed changed the icp, fuel filter and I have checked oil level. Also used fuel cleaner. Still had no luck. When I changed the icp sensor the check engine light came on and was no change I then got a ford oem camshaft sensor and my truck fired right up but still sounded like it had a little miss here and there drove it for a few weeks fine now back to the same thing it will start up and idle fine for 10 seconds then start the rough idle but won't stall out anymore just idle rough. I am stumped I can't get any codes to pull up and if oriellys uses there scan tool while the truck was running it would shut the truck off! I can't find any answers.
View 8 RepliesFord 7.3L Power Stroke (1999-2003) :: Engine Just Started Stalling Off Idle And Restarts Easily
Truck has been driving great for a long time and this afternoon after driving fine to work just died 3-4 times while trying to accelerate from idle. Engine restarts easily but the power is soft off idle, the injectors sound noisier and then quiet down and will accelerate decently once rolling but something is off I can tell.
Fuel pressure is read post filter and is good. Truck is well maintained with all the basics replaced in the last couple years. Could this be CPS going out even if it is only a couple years old? IPR is new in the last year, ICP sensor isn't leaking. Most recent change was a full tank of fuel yesterday afternoon and on a whim performing a boost leak check which was all good.
Ford Super Duty (1999-2016) :: 2003 F250 Keeps Stalling / No Power And Rough Idle
The 2003 F250 5.4 Superduty has no power and keeps stalling. If I floor the gas it just stalls. I've replaced the pcv valve and line, the fuel pump relay, the fuel pump, and cleaned the tank, changed out the gas, added Lucas, and it just won't run right. Desperate, and no codes are coming up...

My truck has been having idle surge, low engine power, says stable tracks is off, computer said TPS pedal sensor. I replaced it. Within 3-4 days my truck does the same thing. I turn it off and eventually my truck runs fine with the exception of my engine light is on truck runs good. I put the computer on it again while the truck running bad and it continues to say it is the TPS sensor.

1996 GMC Sierra SL V6. Owned since new. 100,000 miles, never tuned up. I decided to get a tune up in hopes of increasing mpg, and it was overdue really. New plugs, wires, cap, rotor. Got truck back and it runs rough, knocking, skipping, hesitating, bogging down when trying to accelerate, rough idle. Went from 15.5 mpg, down to about 14 mpg. They said they put in all AC Delco parts. Brought it back to them twice now and they cannot figure out the problem. It ran PERFECTLY before I send it in for a tune up. No problems whatsoever.
View 2 RepliesSierra :: 2000 - Rough Idle When Start During Cold Weather
2000 Sierra 1500, 5.3L engine. When he starts it in the cold (below 40 degrees) at first hits 1000rpm, then immediately drops to 400-500rpm. The idle is rough and wants to die if he tries to drive it. However after 10-15 minutes and the eng warms up, its fine no problems at all. There is no codes, so the scanner we had didn't tell us anything. He had cleaned the TB and intake system with cleaner, no dice. He also disconnected the IAC while it was idling rough, that didn't change the way it ran at all. We would like to toubleshoot it more before we start throwing parts at it.

My truck out of nowhere will start to idle low and die when put in reverse or drive then on other days sometimes it will start and run right. I got the code 44 witch it could be a o2 sensor but tomorrow I'm getting my catalytic converter took off and run straight pipe do I still need a o2 sensor without a catalytic converter or what's causing lean exhaust?
View 9 RepliesSierra :: 2000 5.3 Sierra Suddenly Overheated In Cold Weather Then Fine
A friend of mine has had this 2000 Sierra since new. It has just over 100K and never had any cooling issues before. Last week when it was about 10 below zero she drove it home and it overheated and pumped a couple quarts of antifreeze overboard.
She refilled it the next day and it was fine but got it looked at by a local independent mechanic. I had told her that it was likely a sticky thermostat and it ought to be changed out anyways due to its age. The mechanic thought I was wrong and that she had driven it off to quickly in the super cold weather.
Sierra :: 02 Dies As Idle Drops When Slow Down To Park Or At A Stop Sign
I got a 2002 sierra 1500 with a 5.3l. I just replaced both catalytic converters and y pipe. After I did this, I am having a few problems. First, when slow down to park or at a stop sign the idle drops way down and it dies. I cleaned the throttle body, maf sensor, and ran a can of seafoam and a can of b12 chemtool through it. It did this for a couple of days and now when the idle slows down the "check oil pressure" light comes on before it dies. Then yesterday the "check oil level" light started coming on. Is this all related, would the low idle cause low oil pressure, where to start?
View 1 RepliesSierra GMC :: 1998 - Engine Misses At Idle And During Driving Speed Range
I recently had intake manifold gaskets replaced in my 98 gmc sierra 4x4 pickup 5.7 . The day I drove it home from the shop it ran fine, even day after but the next day I noticed it seem to idle a little rough and even at normal driving, sometimes seems worse than others. No service engine light has yet to come on. Could there be vacuum leak, trash in intake or bad wires and plugs. Plugs, wires, rotor button and distributor cap are only year and half old.
View 1 RepliesGmc - Sierra :: 2000 - Heavy Sound Of Marbles Banging Around Near Front Of Engine At Idle
2000 GMC Sierra 2500 6.0L gas engine 150K miles. After returning home from a 150 mile drive, I notice a very heavy sound of marbles banging around near the front of the engine at idle. The noise is a much like heavy detonation where timing is badly off kilter. Used my stethoscope to determine this is loudest at the water pump housing. The belt runs smoothly with no sign of unusual resistance. The engine does not overheat, and there is no sign of a coolant leak.Can a bad water pump shaft bearing make such a tremendous "cackling" noise? What else could it be?
View 8 RepliesSierra :: 2003 - No Fuel Pressure At Cold Start
I have an 03 Sierra Half Ton when the engine is warm it runs fine but at cold start, half the time it doesn't have the fuel pressure to start, i have to turn the key a couple times to build it up. Idk if the fuel pump is weak for if it would be more the regulator. I started having this problem after i replaced the fuel pump. The fuel pressure gauge shows 50-55 lbs, but every now and then when its cold it will only jump to around 5 lbs (but this is only when the engine is cold... why?) What should i go after first? Regulator, new pump, Replace the fuel filter again?
View 2 RepliesGmc - Sierra :: 2003 - No Cranks Or Clicks / Just Complete Silence
I own a 2003 Sierra 1500 SLT Extended (4-Door) Cab which I bought brand new. It currently has 120k+/- miles on it, but the problem I'm about to describe started about 5 years ago. Here's the issue: Whenever I first attempt to start my truck, I know the odds are 50/50 that it will actually start. When I turn the key, it will either crank right up like it's brand new or it will do nothing at all--no cranks, no clicks, just complete silence. When the weather is colder, the chances it will start are slightly better.
Those chances go downhill as the weather improves--the frequency of "non-starts" increases. I have had a whole lot of mechanics--both physical and virtual--try to diagnose this problem. I even left my truck at a GMC dealership for 4 days so they could replicate the problem and diagnose it. Unfortunately, my truck started on every attempt they made which was 2 or 3 times per day. The only hint of where the problem my lie came from an automotive electronics technician. He said he can't be sure unless he replicates the scenario, but he said the factory installed alarm system is most likely the cause.
