heres the set up, bult bottom end b18a stock head, stock ign, walbro, 750cc injectors, t3t4 , crome.

having a very intermitent problem, i go to start my car after class, and it it sounds like im running on 2-3 cylinders, black smoke everywhere raw fuel smell is in the air. wont idle for shit. come back couple hours later its fine. so far, have got new plugs, new plug wires, new cap, new rotor, diffrent dizzy from a running car. STILL have this problem can anyone please explain whats going on, i get stranded 4-5 times a week at school and it sucls. took it back to the tuner and says the tune is good, even burned a new chip. im almost ready to throw in the towel call it quits and sell the damn thing.

will do it any time,at cruise(will sound like the car just suts off nothing when i hit the gas pedal but eventualy comes back sounding like a wrx) underload, same what i just mentioned, and when sitting in the heat, starts fine in the am but afternoon, forget it. can anyone help i will PAY some one to do it. i really dont want to sell it.

 

oh yeah and sometimes it will just turn off at idle, no bogging or anyhting just sounds like the key was turned off. then will start running like shit when it starts back up.

 

sounds like the tune to me....flat out just to much fuel.

If I recall you were dyno tuned , but not on the street for driveability.

 

Sounds like you need a partial throttle Street tune ...

how old is your fuel filter?

 

are your injectors high impedience?

 

it was dyno tuned, and when i started having this problem, i took it back to him and did a street tune and rode around awhil then he burned the new chip. says somehow the tune he put in before "changed" and some how i got leaner, which is impossible i havent touched the motor. i called to day and he is saying it could be a mechanical problem

the injectors are precision 750s, not suree on the impedence.

fuel filter is probably 6-10 months old.

 

also it mostly does it when underhood temps are hot. ex. driving for a period of time. sitting in direct sunlight for hours. i parked under a tree today and i had no problems. im taking it into CFT again saturday and see what they can do. but from what they have told me they have no idea whats going on and pretty much said im on my own. so,, yea

 

my buddy with a 94 teg rs has had some probs with what i think he calls "hot starts". the car doesnt even crank over when, just like you said, its hot outside or the car has been sitting in the sun. i dont want to overly generalize your prob, but you may want to look into some sort of electrical fault that was pre-existing in the chassis.

it seems to me, and im not too familiar with the intricacies (sp?) of turbo electronics, that any intermittent type of prob would not indicate hardware malfunction, but rather an electrical or programming issue.

either way, i hope you get it worked out man. GL.

 

well in my old accord the car would start up just fine if it was cold...but as soon as it heated up or sat in the sun...it wouldnt start for anything...it ended up being the ect sensor i believe? engine coolant temperature sensor....and i had changed EVERYTHING else....i was pissed lol
