So i got my 92 stealth rttt this summer and it has been quite the project for me. This is my first project car and I am deffinitley learning alot. I have fixed alot of the little problems and now as far as I can tell it has one last problem to be fixed and im hoping to have it going before winter.
So, the problem: It looks and smells like it is running rich at idle. I can drive just fine at lower rpms, but as soon as i make boost, it bogs down and if i continue to give it gas it dies and has trouble starting again (because its flooded?). Im also not sure about my turbo situation. Without the car in gear, i can rev it up just fine but im not making boost (im not sure if that is normal or not). I remember when i first got the car i could rev it up to 4k and here the bov woosh but not anymore. It doesnt smoke or make sounds like a blown turbo though.
My thoughts are the fuel to air ratio is being thrown of by a bad sensor, either tps or maf. I havent been able to find info on how to diagnose either of those though.
Additional info:
Fuel pressure is fine, I installed a ninja performance guage on the fuel rail which i highly recommend.
The ECU is new
It had a very unproffesional engine swap and the wiring is kind of a mess so that could be an issue but im not sure.
Thanks for reading, let me know if you have any helpful ideas or need more info. I plan on actually posting pics once I get the thing running right.
