Possible bad spark plugs or plug wires. Might also be dirty injectors. When last change of fuel filter? Less likely--bad coil pack.

My 1994 buick lesabre misses out


Check the fuel pressure. It will tell you if the pump, fuel filter, and fuel pressure regulator are all good. Fuel pressure is critical on fuel injected engines.

Check your spark plugs for wear or the wrong gap.

Another possibility is a vacuum or air leak. Check all vacuum hoses and the intake manifold gasket. The GM 3.8L engine is prone to lower intake manifold gasket failures. Sometimes the upper intake gasket, too.

Low oil pressure, trucks runs rough after it warms up, can not drive highway speeds it jumps and spits


Have you tried to replace the oil pressure sensor - it helps regulate your oil pressure in your vehicle. Not an expensive part but they do go out from time to time.

05 Impala missfire code 301 have changed


check intake for vaccum leaks,the gasket also and egr valve, thats alot of parts to have replaced without diagnosing first, if there are no fuel leaks and you said all injectors were replaced then you have a defective fuel pump, also these engines had misfire problem because of dirty injector but you replaced them so count that out. good luck.

Car would not start so replaced battery, then alternator; Ran great for roadtrip then shut down on the freeway. Can hear the fuel pump, so replaced the fuel filter; has spark. Has fuel. Wires are in good...


WHEN A CAR SHUT DOWN ON HIGHWAY OR FREEWAY.YOU CAN STILL HAVE FAULTY FUEL PUMP.IT COULD BE RUNNING BUT THE FUEL PRESSURE CAN BE TOO WEAK.THE 2.5 ENGINE FUEL PRESSURE IS 6.0 TO 7.0 PSI AND THE 3.3 ENGINE FUEL PRESSURE IS 37 TO 43 PSI. ANOTHER THING CHECK TO MAKE YOUR COOLANT IS NOT LOW.LOW COOLANT CAUSES ENGINE GET TOO HOT SHUT OFF.CHECK PVC VALVE AND EGR VALVE MAKE SURE THEY ARE NOT STUCK OPEN OR DISCONNECTED.AND MAKE SURE IDLE SPEED IS NOT TOO LOW YOU IDLE SPEED IS ON THE FACTORY STICKER UNDER THE HOOD.

95 GMC Jimmy 4.3l W vin rough idle


My problem was solved when I repaired my 4 wd activation dash switch. The switch was contacting on 2WD & 4HI at the same time. The front differential activation is vacuum activated possibly creating a tug of war that didn't actually engage it but drained off vacuum from the engine? A theory at best but stumbbled across it because I knew the switch wasn't working properly I repaired it and low and behold rough idle disappeared and all is good for 3 weeks running.
