When we are supposed to be getting more air flow we get less


have u had the computer scanned? any emissions codes? That could be anything from throttle pressure, throttle positioning sensor, mass air flow sensor.Step 1 would be scanning the PC & checking the emissions. Good luck.

P0122 code comes up but we replaced the sensor and it is still coming up


Code 122 means the signal coming from the throttle position sensor to the engine computer is low or out of range. If you have replaced the sensor and it is calibrated, the problem could be in the wiring back to the computer. The sensor is telling the computer the throttle is not in the correct position, or not sending a signal at all.

My 1996 chevy tahoe has rougha rough idle and low r.p.m's in drive what can i do to solve this problem


I would do a full tune up first. Plugs, wires, rotor, cap and coil. If your idle is still rough consider MAP sensor, idle position sensor, or any other emissions sensors maybe suspect. They usually set codes that would trigger your "check engine" light. On the other hand check belts and tension pully if you have one. Lastley, change the fuel filter put in some injector cleaner. A good shop can test the fuel pressure from the fuel pump. I hope this can help.
