Egr, tps, maf o2, starter battery the computer but I'm having problems still with my Acceleration. The computer is only getting 2.9 volts but needs 5 so it won't read when I come to a stop light the battery Gage goes down then has slow speed but it also sounds like the idle speed goes down I think it could be a wire but I don't have a clue some good info would really help thanks

Well when ever I take one of the grounds off the voltage goes up one thing I forgot to mention is that it will back fire or miss fire I can't tell but I don't think it's the alt but seeing is how the comp will not read it's hard to figure what the problem is

Springer Spaniels Rule
It might work but without the proper voltages they wont work right and kill the engine. The harness plugs are around the steering column, its either round or rectangle, and reading again if your batt gauge goes down, could also be the voltage regulator going bad,
