Question about 1997 Buick LeSabre
Car is idles high i have changed throttle postion sensor and idle air control and still idle high i put a code reader on it reads P0122 = tps/ pedal position sensor A circuit low input also reads P1406 = egr valve car is still idling high
at one time the car run right but it would not shift in to gears and it stalled
do you think it could be the computer????
It sounds like you have a vacuum leak or intake gaskets leaking. Try this. Start the engine and let it reach the idle it want to go to. Get you a can of Brake Clean and spray it around the intake manifold (it on the top center of the engine, you may have to removed a plastic cover) If the engine idle changes up or down then the intake gaskets are leaking hence your vacuum leak. I hope this will help you.

had same problem i would check the Idel Air Valve and also check all of your vaccum hose lines makeing sure there are no cracks or splits in rubber connectors if there is repair immediatelt because over time they start to dammage the internal parts fo the engine and if youve replace tps mass air etc. sounds like a vaccum hose problem
