98 pontiac grand prix gtp short or bad tps
I have 98 pontiac grand prix gtp series in throwing
a 5v reference 1 code and a tps code I have
replaced the tps 3 times done coil packs ecm and
maf. It will start up fine but my gas guage wont
read and dont want to shift until 4 to 5000 rpm I'm
at lost with the car so anything will help!
