Does a bad fuel regulator cause the engine to have a rough idle? It feels like the injectors are clogged when starting up. So the car would have a hard start. And when started up, the car would have a rough low idle. Feels like the engine would just die. I already changed the fuel pump, fuel filter, and even added some of those fuel injector cleaners in the gas tank and the problem still presist.

 

could be a misfire. did you do a tune up

 

exhaust putter??? sounds like a lean condition, are you chipped on bigger injectors for that HMT setup???

 

no actually this car is completely stock to the bone. no mods or anything.
