Ok so I got this OBD1 nightmare in the shop as a failed transmission problem. Which turned out to be the first of many problems. So to start with, the engine will not idle, you can hold the accelerator giving a slight load and it will stay running, (very poorly) with obvious misfires. The low oil light remains illuminated during this despite having the correct volume of oil. So I pulled the covers to get to the plugs and inspect them, low and behold #5 plug was fouled. Replaced and tested, no fix. Now I started looking to other ignition issues PCV valve hose removed and it would idle fine but still misfire. Wires look new, the insulators look fine. Should I check for plugged exsaust next or injector issues? Or even fuel pressure regulator. I got to admit, pre OBD 2 stuff is a mother to diagnois and I'm just going in circles here lol. Any tips?
have the same problem?
