May be a fueling issue, sounds alot like a fuel cut, does it jerk real bad when you try to accelerate or just stutter and stumble?

I had a similar problem right before I sold my car. Turns out it was my crank shaft pulley. Do you hear a clicking noise coming from your engine bay? My RPMS would jump around a lot at random times, my car wouldn't accelerate, and sometimes it would just die until I jump started it. Not only was the pulley bad, which caused the clicking noise, my belt barely had any teeth left on it. I couldn't believe that my car lasted as long as it did with the issues I had in that respect.

Ran like brand new after replacing the pulley and the belt.

that problem stop..now i can accelerate pass 20mph ..reset the ecu..back to normal for now. took off the throttle body clean the carbon, wow it was dirty..also remove the TPS and i couldnt find a way to clean it..so i put it back on ..now my rpms are back to normal. the idle use to be so rough..now it idles normal.

now my last problem is this right side cv axle, is so freaking annoying i just replaced this shit...and its pissing me off.. the boots aint even broken ..i think i got a broken axle..it clicks but not torn..what you guys think?
