Well not quite the weekend I had hoped for. Finally got around to installing my Accufab SBTB and plenum this weekend and now the car is out of commission.
When I first fired up the car after install it sounded like it ingested a cat. Very odd sucking/wheezing noise from the engine, followed by a very rough idle, stalling and a strong gas smell in the engine bay. I triple checked all my vacuum lines and sensor connections and couldn't find a smoking gun. After some research I found I needed to adjust my TPS voltage. Accufab recommends between .98 and 1.0v at idle, was able to get this set right in the middle at .99. This helped somewhat, but still odd noises and won't idle.
I began to wonder if the idle set screw on the Accufab piece was out of adjustment and starving the engine of air, so I put the stock throttle body back on to see what would happen. Same thing, rough idle, stalling, odd noise around the intake. Absolutely no idea what the hell is going on. I have a friend coming by with a spare FRPS tomorrow to try that out as I saw some threads saying those can go out without warning. But I'm not convinced it's my issue. It honestly sounds like it pulled something into the intake and is choking on it, but there was no packing material on or near anything and the filter and MAF are both clean. I also checked the IAC passageways and cleaned the IAC valve.
At this point I am very out of ideas and incredibly frustrated. Any ideas / thoughts / suggestions are appreciated. I tried to get some video but I didn't have anyone around to hold the phone and couldn't find anywhere to prop it up.
Thanks all.
