I have had my 91 laser turbo (fwd) for about 2 months. when i bought it the guy sold it for 600 saying the turbo was "bad" . it was actualy a blown computer which i figured out and swaped withen the first few days. well the car ran like it should for about a week and then started on a new problem. Now it has an idel problem while sitting still jumping from 1k to around 600 rpms. also the real problem is that i cant go wot , if i ease on the gas just a little it is fine but when its floored and the boost is up it will go and then stutter and the boost drops back to vacum and the car acts like its choking out. this only happans when its floored or not easily accelorating, when easing on the gas it runs fine boost presure and all. I replaced the injectors, fuel rail , plugs , wires , of cours oil and filter. i cant figure out if there is maby a boost leak in one of the hoses maby intercooler piping (all of which is stock) or a vaccum leak perhaps? Iv worked on cars for awhile but this is my first turbo so i was hoping i could get some feed back even a few suggestions. My girlfriend also just got a 90 exclipse gsx thats in my garrage. it needs some tlc. the turbo on it is indeed bad and we already have a replacement td05 sitting next to it , just need the time to work on it. Any advice is much apricated. Thanks
