ok, i got my 96 rs twin turbo, with frontmount and aftermarket blowoff valve.
SOMETIMES (usually hot) under very light throttle, just about to come on boost, the car splutters and loses power, runs rich (can see black smoke from exhaust) then takes off and is sweet. this only happens as its about to come on boost on the primary turbo. happend the other day, got really bad on the motorway so i pulled over to inspect all my hoses.
seemed ok. so i went to take off, and it ran like absolute ****e, then died at 4 grand, so i grabbed 2nd and floored it, same thing, 4 grand power cut. then got third and it died, so i got off the gas and tried again, then it took off and didnt have another problem the whole trip. yes i will check for codes tomorrow, it didnt have any last time i checked bout a month ago, anyone got any ideas what this problem is?
to me it sounds like an air leak after the turbos or the afm or even some of the symptoms of code 66? just looking for a second or third opinion from people that have a bit more experience with these cars then me haha
