hello ht i been trying do get my car runing good but its stil idle like crap every once in a while.i have been told that 1 3 piston arent working.idk.i switch fuel injectors around still tha same.it throws sparks.wen im at a stop.it will idle good then drops and wants to shut down.is it really the pistons or sumthing stupid.thank!

 

wow check your timing

 

tried that twice.still nothing

 

Check the valve clearances. You may have valves not seating properly. If there is damage, you may be able to get away with bolting on a good used head.

 

ok.i re did my timing today and it runs better.jus wondering piston 2 4 wen i take off the spark plug wires it stays tha same.is that normal?it did it b4 too.1 3 it dies of course.

 

Gimme advice on wut could be wrong

 

You have been given some advise. Pull the cover off the head, grab a set of feeler gauges and check your valve clearances. Do this with the engine COLD. Let us know the results.
