i have a 90 civic hatch. put a 90 ls motor in it. when i floor it, it does not go anywhere. it is like it is dragging. also the damn thing overheats. dont no if it has anything to do with exhaust. all i have on it is header a downpipe. i think it could possibly be a fuel problem why it is not running right. put a new thermostat on it. on the top radiator hose, when u squeeze it, aint it suppose to be like there is fluid in it. if so, i a not getting flow thru the radiator. maybe overheating problem. need opinoins, please help.

 

is your water pump working? as for the performance I would try cleaning out the injectors also check your O2 sensors. Does the car idle fine or is it rough?

 

lol

 

check ur spark, if its hesitating i dont have enuff info to diagnose it i seriously doubt its ur heads/downpipe,did u rehook ur o2 sensor? i forgot to do that one time on a supra i owned and im like wtf whys it running like this, CEL came on..

 

check ur belts too. and idiot check the fluid level

 

my dizzys fucked up in my hatch, so it throws a CEL and wont let you go past 3000 rpm, bogs out after that...

 

what the hell. i made this thread in June 2003. look at date before u post please!!!!!!!!!!!!!!!!!!!!
