As some of you may know I'm new to Toyotas and I have a couple of questions. I purchased a 1985 4runner from a man who thought he was a mechanic and tried to fix the truck, to make a long story short the truck ended up worse than it was. Well I have worked my way around the truck and got to the point where I realized the computer was bad, after opening the computer up I realized that it was the root of my problems. The 4runner has a 22R-E engine with the EFI system, the computer that is on the truck is marked as a 22R, that was a concern to me as I dont think this is the computer that belongs in the truck. I read some where that there is two types of computers a 22r a 22r-s that is a california emissions friendly version and that one of them has two plugs and the other has three. Mine is marked 22r and it has 3 plugs, I belive that this is a california truck and I dont think the computer belongs here, am I correct or am I way off?
Thank you in advanced for any help you may provide and excuse my noobness.
