I've been working on a problem for 2 weeks now. I am really frustrated. Okay, I have a 1988 Iroz with the a TBI. The flaps inside the throttle body were sticking to the walls. I took the TB off and had it machined so that the flaps no longer stuck. When I put it all back together, I had a surging idle. It goes from 400-1500 and quite frequently dies. If I hold the TPS open, it idles good. So far, I have checked and cleaned the IAC and TPS. I have checked and rechecked my gaskets and used Carb Cleaner to check for leaks. Its not my Catatlytic, I removed it. I've tried correcting it through various posts, but most posts of a similar problem were never completed. Thank you for any responses.
