Dark Ride Posted December 9, 2012 Report Posted December 9, 2012 My 98 GTP has been running rough lately, it doesn't always like to stay running when you first start it, and it completely falls on its face on take-offs. Reminds me of a cold 454. The SES light was on so I scanned the codes and got P0102 MAF low voltage, P0135 O2 Sensor Malfunction, and P1676 EVAP malfunction? Any ideas, seems bizzarre to have these three show up together. I cleaned the Air Filter and sprayed the MAF with cleaner, cleared the codes and they were back within a block. Quote
vyper144 Posted December 9, 2012 Report Posted December 9, 2012 Replaced the failed MAF on my Impala. I only found out because of an error code. It wasnt causing me any problems... Quote
95 vert Posted December 9, 2012 Report Posted December 9, 2012 Needs the MAF. MAF can cause 02 codes. Try a different MAF and see what codes return Quote
