Try changing your pcv valve. if that dont work it could be your mass air flow senscer or throtle pasistion senscer
yes, of course there is. if the cylinder head gasket is burnet through, one cylinder fills with water and then the car runs on only 4 cylindres and the compression is too low
Also, the Toyota Tacoma 4X4 SR5, without Keys, parked, no one in it?
If your 4 Runner shakes when it is idle, it is in definite need of a tune up. The shaking could be from a variety of things, including the fuel filter being clogged or even a cylinder misfire.
Have it checked for codes. There will be a misfire code that will let you know what cylinder has the problem.
my idling on my 2001 ford focus is not idling correct, tried to adjust idling but there is no screw or way to adjust why?
You most likely have cylinder misfire. Check your ignition coils and spark plugs.
Knowing the year would make a difference. A good STOCK 350 should have at least 150 PSI per cylinder. You CAN'T have any more then a 20 LB difference in any giving cylinder are you will have idling problems.
Because even idling engines use fuel.
Mine is between 500 and 600 rpm's after the engine is warmed up.
you have one or more cylinders not firing causing imbalance. check for spark at each cylinder.
I had the same problem on my car. turned out to be a blown head gasket. the no. 1 cylinder was pushing hot gasses into the coolant jacket.
I sat in my car in the driveway with the car idling, waiting for the kids to come out.
