I changed the intake gasket the other day in order to fix aa antifreeze leak. After all was completewd and everything hooked back up, it seemeed to run fine, though the timing was off. After trying to adgust out the timing by the "test Drive technique" It seemed to get worse when idling. I'd had a problem with the idle geting really low (stumbling) after reving it in drive with the brake on. Anay way It has gotten worse to the point where it will not idle without your foot on the gas. I replaced the Idle air control motor last night and it didn't do a thing. This morning it gave me a 22 engine code. That means something like wide open throttle circut grounded. Is this my problem? Would this mean the TPS is bad or something elyse? Is it possible that my distribuor is off a tooth? Please help as I am ruining my brakes by keeping my foot on the gass!!!
