Ses Light On And Off
Could be alot of things, When I removed my air, egr, and cats I got 8-10 codes. Take the car and have it scaned or if you know anyone with hp tuner to get the codes out. That will tell you exactly whats wrong.
Go to Autozone or find someone who has HP Tuners, etc. and get it scanned. My car did the same exact thing when my driver's side o2 sensor started going bad. If you get it scanned you'll know for sure though.
