ok, im having problems with my hatch. the single cam ZC i have isnt idling like its suppose to. it ran fine up until yesterday. its idling well below 500rpms, and when i get it throttle it like bogs out like hell, then i get this *plump plump* sound...and once its gets going to around 1000rpms its revs up, but not like it used to. and if i hold it steady at 1000rpms, then push the throttle all the way down it bogs then revs up. IDK what the problem is could it be a warpped head??...i cant see any leaks coming out...and theres no check engine light. HELP!!!!

check your timing and check your tps. better yet check your ecu to see if its throwing any codes. i think you should check those things i stand corrected.

ecu isnt throwing any codes, and my tps sensor is fine. ahhh...im getting frustrated with this!

 

check your timing if it aint none of thy above and you cant figure it out. i dont no whatelse to tell you. but to take it in somewhere to get it checked the sooner you get your car back up and running.

 

anybody else can help this guy out if im wrong.

 

What about all your Vac lines ?
Map ?

 

a buddy of mine and i checked all the vac lines, they are all hooked up right, no leaks in any lines...map sensor is good. still not throwing any codes...but i did find a massive head leak like 10 mins ago...im thinking its a warpped head?? any other suggestions?...im think im gonna take the head off and have it re-surfaced....would that help?

 

it might help but it would be cheaper i think if you come up on a head on the classifieds there dirt cheap.
