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 ****. 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 **** when it starts back up

 

bump to help the man out

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

what kind of smoke, like kind of white or what?? Cause if it is a little white is is probably your head gasket

those are the classic symptoms of a bad main relay.

it's strange that you can get it to run under those conditions at all if in fact it is the main relay, on bad MRs I've dealt with either it will run or not. I've seen them cut the car right off while driving down the street too.
