Hi i have a 1989 supra 7mgte. I got the car running after putting a new hg and putting in new valve guide seals and cam shaft seal. Also i put i new turbo set up on. Now the thing is that i got it running but when i cold start it it runs fine revs fine idles fine but as soon as it starts to get warm it wont idle. I can still rev it fine but i have to feather the gas to get it to stay running. It does have the maft pro in it and i dont really know anything about them it was in the car when i bought it. It does smell like its running super rich. You can smell the gas. Also was wandering i dont have the exhaust put on its just straight downpipe from the turbo would that make a big difference or not. Anything would be anything would be greatly appreciated thank!
