ok, long story short.. I put a new ported plenum and TB from amazon on my car, reset the pcm.. took the car out and hit the rev limiter which blew my fuel pressure sensor. Car started to miss bad at a stop light, it would dip down to about 400 rpm, then back up, back down, etc, etc. I changed the plugs after it started missing thinking I had a bad plug but found out it was the fuel pressure sensor.. So I then got a new sensor, installed that, changed oil, reset the pcm and it's still missing. It's fine when I first start the car but after it runs for a few minutes, it will start missing when stopped at a light. I'm going to try and put new plugs in this week to see if that will fix it.. Any other ideas?
Thanks
John
