sounds like the timing is off
crankshaft sensor going.
check for vaccum leaks.
On my Chevy truck it idles high when its low on antifreeze but if its not that more than likely its usually a vacuum line loose or cracked. good luck.
check make sure the firing order is correct.
may have plug wire crossed
whats the first step on repairing my 1993 Toyota truck 22re with a high idling problem thanks Brian
Starts hard then it rough idles for a short time then smooths out but when you give it gas it miss fires and bucks and does not smooth out.
I believe it is in the casting on the intake manifold. I would have thought 1432. It backfires or stumbles or idles poorly when it is wrong, so you know immediately.
its most likely your idle control sensor. if you replace it the truck should run fine.
I filled 1/4 gas it was almost emty. I drove 3 miles when my truck just died. sounds there somethig wrong with the gas because is has power but wont start.
Factory pressure is 75psi. However, the book says that the truck will run fine as long as the psi > 50. Mine is currently 52psi and the truck runs fine....idles a tiny bit rough sometimes.
Ask this question again specifying what the car is.
