Hello. I recommend that you go to any auto parts store and purchase two bottles of dry gas and one bottle of another fuel additive called Seafoam. Pour all three bottles into the gas tank. Then drive for a few miles and you may have solved your problems. Joe

Idle marks 1200rpm but sounds to low


Could be the tach isn't accurate at low rpm, that isn't unusual. Try connecting an external tach for testing.

My 2002 Hyundai Santa Fe with a 2.4 motor (110.000 miles) runs very ruff when the engine is cold. I have to keep the gas pedel pushed down to keep it running. When it runs about 4 minuites it will ru


Could be a problem with the fuel system or a vac leak.
The engine requires more fuel when the engine is cold.
You may need to replace the fuel filter and have the fuel pressure checked with a gauge.

Rpms runnning over 2000 jeep cherokee laredo 1997


Maybe the Throttle Position Sensor (TPS) if the computer thinks it is all the way to the floor then the gears would not shift until the engine RPM is real high. Also would not be able to determine the car is supposed to be idling. Do you have a check engine light? If you do this may come up on a scanner.

MIL light flashing means vehicle running too lean, not enough gas to the cylinders or timing out. Check if the spark plugs are correctly pluged in (firing order)

Ruff idle on my 2001 for taurus. At higher rpms it runs fine.


It is most likely you wheel alignment (costs about 20 bucks to have your wheels aligned) or try checking the tire Pressure to make sure they're all even maybe hope this helps

My integra bogs down at higher rpms


First run a tank of a strong fuel system cleaner like BG-44K. If that doesn't help, clean the throttle body. If that doesn't help, take it to a mechanic.

Rpms drop at high speed, mo matter how much gas applied.


Most times they will attach fuel pressure gauge and tape it to windshield or whatever is necessary, then run it down the road to duplicate conditions when you experience your problem. Perhaps fuel pump is getting weak and cannot supply enough fuel to maintain higher speeds etc. Have had ones that had proper pressure when cool, but after running a while, pressure drops right off. It's going to be a process of elimination right now, as no codes coming up, so If you have good spark at all times, then fuel pressure is most logical thing to confirm next. Can you include which engine as well, it may help narrow things down a bit too.

Have you tried changing your fuel filters or using a diesel fuel injector cleaner. You could check your air filters also. It sound as though it is having trouble with fuel or air flow. If these both check out try your idle management control sensor You may also want to check the injectors for blockage

High RPMs


Check all vacuum lines to make sure they are connected. Your problem may be in the transmission too.
