Re: 89 gmc lean running condition
My truck had a bad ground. It made the oxygen sensor read lean, really lean. The computer dumped a ton of fuel into the engine, it ran horrible. It's supposed to bounce back and forth between about .3 and .7 volts, mine was in the negative. So I would check the oxygen sensor readings.
