my car (85 gs stock 12a) was running smooth befor i added the header and dlidfs and now it has a little miss. at idle. sounds kinda like its running retarded. do i need to change the timing after doing the dlidfs??

 

Hello??

 

Is the engine shaking or are you hearing a popping noise?
Their should be no need to change the timing.

 

its not shaking. i hear kinda a deep poping sound at the header. the engine starts smooth and after afew sec. it wil miss and abuot every sec and a half it will miss. at first it was missing bad and i found a bad ignitor to L1 i changed that and every thing is geting spark. butt it has a small miss still. i'll re check all the vac. lines when i get home

 

Check for exhaust leaks also. A small amount of popping is normal. That is unburned fuel in the header.

 

ok thanks. if the unburnt gas popping in the header is normal thats fine with me. eney ideas on the miss??

 

Did you replace the plugs or are you still running the old ones?
