hey guys i have no throllte response over 1/2 throttle and and i have to keep it to the floor for it to stay running have no codes.i have no idea what else it could be.timing is good i set timing and it got better.i cleaned plugs and gapped them.

 

what is your compression?

 

what does compression have to with this?

 

when my head was cracked i had the same issue compression would tell you if its cracked

 

my dad checked the compression and said it was fine.i mean it runs and then its really choppy almost like a misfire or running on like 3 cylenders.put there all fireing i checked for spark on all the plugs and checked all the injectors and there all working.but ill have it idleing for a minute or to and it will shut off and when i have it to the floor it idles at like 800 rpms.but if i move the throttle on the t/b it wont go more then 1/2 way or it will bog out like its getting to much or to little fuel

 

headgasket? what does your oil or coolant look like

 

i just put a head gasket on it.and then this started happening.i didnt disconnect anything i had the cherry picker there and just lifted the head cleaned the gasket off it and the block cleaned the chambers and put it back together.i can stick a screw driver in the chamber and its dry so i know i didnt blow it again or have a cracked or warped head

 

any other ideas like any sensors or vacum lines that would cause this

 

wait you just put a headgasket? are you sure that the timing is right? you can try and check the tps by getting a volt meter and checking it at closed throttle and WOT.
