When I start my '92 SC there is sputter at idle. It is not constant, or a back to back sputter, but a put....put, put.....put.....put, put, put. I did this before I pulled replaced the headgaskets and stopped afterward. I pulled it down to the heads to retorque my lifters and after putting it back together it is back. Initially it idled like crap and I pulled a lean left bank code. I resealed the upper intercooler tube and most of the issue went away. I have also checked all my vac lines and connections. I ran codes again and it passed. My local shop kept it a day and found nothing. Suggestions? Comments? Sympathy?

Thanks!
Raymond

I would go over your all your plugs and wires. It could be something as small is that.
