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.:think: I cleaned the Air Filter and sprayed the MAF with cleaner, cleared the codes and they were back within a block.

Replaced the failed MAF on my Impala. I only found out because of an error code. It wasnt causing me any problems...

Needs the MAF. MAF can cause 02 codes. Try a different MAF and see what codes return
