Question about 1992 GMC Yukon
Usually starts up fine, not the fuel pump or filter as we checked that. Has holes in cat so not clogged up. Driveable but sputters and wants to die if we step on the gas. Idles fine.
Is this a missfire? have you replaced the MAF sensor which is a common cause of this, if over 100,000 miles replace plugs and plug wires as well.
