Just passing on the fix, picked up a Snap on MGT2500 graphing scanner with software(e-bay) plugged it in. The codes for TPS and MAFS where thrown. went to Rock auto bought the throttle position sensor, mass air flow sensor the TBI gasket, installed the parts, cleared the codes and fixed. after the test drive the check engine light went back on. plugged in the scanner and threw the MAP sensor code. replaced that and fixed. Driven over a thousand miles and no check engine light. oh yeh that shift problem with the trans mission I had. ALSO GONE. The total fix under $220 dollars. scanner priceless.
