I know that won't happen as I'm sure the wife has plans for me. Car was acting goofy again last night. It randomly/intermittently develops a stumble like it has a vacuum leak. When this happens if I put it from park to reverse, the rpms drop 400-500 and it stalls. Had to brake hard last night to avoid a car and she stalled out in traffic. Started right back up, but every time I tried to put it in drive without extra gas it stalled until I got moving again. It has been doing this off and on for 2 years. The new setup has a new intake and new throttle body so it's not that. It has a new IAC, did the same with the old one. Thought the booster might be leaking internally, so I removed and capped the line, but it stalled the same way in reverse as when connected. Checked for vacuum leaks with propane the other night, nothing. So now I'm thinking one of three things could be causing it - intermittent TPS, intermittent maf problem, something strange in tune related to IAC. Timing was good last time I set it, but I'll recheck it. I think I have an extra TPS in my parts box and I have an extra MAF I will try. I just want to sort this out, it's annoying. Hope everyone has a great day! Matthew |
