car is a little sluggish on acceleration, smells rich, and wants to almost die when i come to a stop. i'm thinking regulator, but not sure. any ideas?

 

any codes? last time car was tuned up? what's under the hood?

 

no codes, plugs, wires, CAI, battery relocation, SOHC, new o2 sensors, temp sensor, timing belt, water pump, headgasket, seems like it runs rich too. would a bad fuel pressure regulator give a rich o2 sensor reading???

 

maybe, i'd think that the pcm would take the o2 sensor info and adj fuel amount though. did it do this befor the t-belt was changed? it's easy to mess up the timming and they run like crap if off. what type of plugs you got?

 

it did, but not as bad as it is right now. i'm running copper champions.
