hey guys! my pile of crap started acting up.. its hard to start the car.. i have to give it gas while cranking ..when it starts it misfires and dont keep the idle. No codes are showing.

here is all the engine mods: front mount, hard piling, hks bov, air intake and exhaust just basic bolt ons. running stock boost.

i replaced the plugs and gaped them (.24-.26) like the guide says got new coils and wires.. and its still doing it

any ideas???

 

If it has a mis-fire, more than likely it will throw a code.

check vacuum lines to see if you have a leak, or if maybe, one might have popped off.

double check to see if you gapped the plugs correctly and the new coils are installed correctly.

 

I see that you have the HKS Bov. Are you recirculating?

 

sounds like a boost leak. Go to home depot and make your own boost leak tester, even if you dont have a leak its nice to have one

 

no im not ..but i didnt really had a problem wit it before

 

not too sound like a noob but wuts all do i need for that? i haved had to do it again before

 

anyone got any other ideas??

 

that wouldnt matter at idle.

 

dang it true that... but i think its something wrong wit valves...im ganna do leak down test and see wut happens

 

ok so everything started after i took my optima out to get it tested...so come to find out the car has Works ECU P2 Flash is there special way you have to reset it ?? because once i start the car and keep the rmps up it runs find but once they drop it misfires and dies but if i keep them up for a while and gradually let off it idles...once i give it some gas it dies...

i did boost leak test and i did leak down test to check the valve... everything seems fine. also i am ganan order recirculating kit for my BOV may be that do anything ..
