i am having problems with my 96 t/a it's been the shop over a week now and still don't know what wrong the car runs not very well though it idles up and down constantly and the car is not communicating with any sort of diagnostic equipment at all but the crazy this is it's sending a engine code for the rear O2 sensor and all it is saying is there is a communication error and he said that they tested all the pins on the diagnostic port and all postives and grounds for the pcm and still nothing what do you guys think may be the matter with the car??? a while back i recently added that piece of junk gms maf!!!(if someone is looking to buy one i'll give it away dirt cheap!!!) and it ran fine for a while and then it started the idle problem even after i took it off it continued to run as if it was still on the car did it posibly do something to the pcm if anyone has had the same problem any advise would be greatful thx
