My civic has not been started for about 3 months (due to the fact that it was stolen and the f***ing thieves stole my obd2a vtec engine wiring harness which is super hard to find). I put everything together and decided to crank it up finally. It started and it had a problem keeping idle and it sounded like it was misfiring... i checked the distributor and checked if all the wires were leading to the right pistons... and they were all correct. Afterwards i decided it may be a fuel problem. So i went to discount auto parts to get some carb cleaner and spray it in my throttle body while the car was running and it revved great! As a result, i discounected the vaccum line to my stock fuel pressure regulator and it did not run great but ran better than before. Do u think this could be my fuel pressure regulator or fuel pump?

 

No opinions?

 

clean your Fuel pressure regulator out and throw some gas treatment in it I also know how hard it is to find that dam harness lol

 

how would i clean the regulator?

 

Use some brake cleaner and soak that thing in it....

 

huh interesting... i will try that and let u guys know

 

ok... it is definetly not a fuel problem... the motor is still not running right. It still sounds like the engine is misfiring so i think it has to do with the electronics. Any suggestions???
