Did you clear the trouble codes with the scanner? OBDII trouble codes must be cleared with a scanning tool. If the codes are not cleared the computer could be in the"limp home mode". Once the codes are cleared, drive the car for at least one day. If there is no improvement, scan the engine again for codes.

2005 Dodge Ram 1500 4.7 Engine. Starts fine, Idles fine, but when engine shifts into high gear and RPM lowers engine runs really rough under load


Have you checked for a broken valve spring. Repaired a dodge engine with the same running issue as you have described and it was a broken intake valve spring.

Why does my saturn sound so bad when idles?


if the car is loud/noisy there is a hole in the exhaust system and this will cause a rough idle because of a loss of back pressure and the vales will not open and close properly resulting in the rough idle it also will make the engine run hotter and this will cause your spark plug gaps to increase and the spark will be less than needed to ignite the fuel in the cylinder for proper combustion which will result in poor gas mileage and lack of power is the check engine light on?

What is causing my 97 mazda pickup to idle rough then die?


2 things could be happening. One, the maf, or map sensore is bad. If there is a check engine light on, have it checked out. Second, it could be the throtle position sensor. Or just crappy gas. Rule the gas out first before changeing sensores.

2000 ford expedition ,,rough idle in park..rough idle in drive,, sometimes dies..rpm's in drive at idle 400...replaced iac


Check the fuel pressure at the rail assembly, there should be a min of 40 lbs at the rails. Do you have any loss of power under a load? You may have an issue with your o2 sensor that is causing the ecm to send an improper signal to the engine ign/fuel map.

Idles okay, runs rough when gas applied


Either a bad MAP sensor, or TPS. What is the code for the check engine light? This will most likely tell you what it is.

1993 olds cutlass supreme 3.1 multi port loading up at idle


Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Engine runs rough after about ten minutes /idles really low


Just trowing some suggestions out there, but, I would check the idle air control valve (solenoid) or the throttle position sensor. If they check out then my last guess would be the map sensor or the vaccuum to the map sensor. Hope I was able to help. Best wishes.
