guys i got this problem on a car im working on. the car has a built motor and a 35r with 1000cc rc injectors! the car idles fine sometimes but then starts sounding like a subaru with a exhaust and feels sluggish, then it will clear up when i take off then come back while driving normally! the car pulls fine throught the gear and builds boost fine then a 7k it starts to do it again. we have changed the coils, plugs, injectors, maf, tune, and also the air fuels are good! all though one thing catchs my attention, when we unp-lug the front o2 sensor it acts the same all the time. at full throttle and part throttle! i dont know what the car is suppose to do when the o2 sensor is unplug? but it does make me think that it should run worse, but it doesnt. i could use any help possible! it does break up farther than 7k also. this is on 93 octane and 22psi, and when it does it on low throttle, it does it when your out of boost but clears up as soon as you get into boost!

ps thanks for anyones time and help!

 

come on anyone!!!!!!!

It's probably related to your tune. Get with Jestr to help figure out whats wrong with it.

 

its not in the tune, we have reflashed the stock image and nothing changed. im thinking something with the o2 sensor, but im not sure?

Well if you flashed it back to stock with 1000cc injectors that didnt make it run rich at all ? And if you unplug the o2 censor did you get a cel ? Normally dont you get one seeing the car reads of it ? Im not absolutely sure just tryin to help maybe you'll realize something thinking it over. lol.
