Hoping the wealth of knowledge I have seen on this site so far can help me with my problems. I'll start with some information about my car. I own a 1988 automatic Conquest, I'm unsure about how many miles the car has because the odometer has been stuck ever since i bought it. The only modifications done to the car are 2.5" exhaust from the turbo back, a blow off valve, all vacuum lines deleted except for the line running to the vac advance and the line for the fpr. I have also removed everything in the engine bay related to the air conditioning system (condenser, compressor etc...) The only problem I'm having right now is when I go into boost I hear a loud crackling (misfire?) and the car feels very sluggish. When I bought the car the owner gave me a set of injectors that i was told had just been professionally cleaned so installed them right away. I have also replaced the distributor, vacuum advance, plugs and wires trying to chase this problem but I'm stumped. The car was running great for about 3 months after replacing the injectors,plugs and wires but crapped out just recently. Any help will be greatly appreciated.
