86 GMC engine question
OK. The engine in my 86 is acting up a little. It deisels or pings alot when under a load. I'm pretty sure my problem is mostly in the smog equipment. The truck only has 48,000 miles, but the PO only drove 7 miles at a time, which isn't enough to clean out any carbon. It probably did more harm than good. The truck ran great for the first 2 months or so, but seems to be getting worse everyday.
My questions are: Is my engine computer controlled? It has an electronic carb, but there is no oxygen sensor. Can I remove my smog equipment, install a new intake, carb, dizzy, and exhaust and still work well with the stock cam? The laws will not effect me here. Please help me. I don't want to spend a small fortune replacing outdated smog equipment.
