timing issue
hey everyone. I was working on my 87 4 runner with the 22re today and was trying to time it to get the miss out of it. The timing was way out but when I got it tuned by ear I hooked the timing lite and it wasn't even on the little gauge. When I tuned it to 5 degree BTDC and took it for a ride it It would barley go. I tuned it back by ear and it runs good but sill by the lite way off! What could be the problem.

If you short the plug and the engine RPM does not drop then your TPS idle -E1 switch (idle switch inside TPS) is not closing on throttle plate closure. You will have to adjust your TPS per FSM. If that contact does not close you will not go into base timing mode and your timing will be advanced to 20+ degrees because the ECU thinks that the throttle plate is not closed.

Generally on these older engines. the more tming advance the more efficent the engine runs. More timing the better i say. but if your just going for OEM which is what like to do. Then jump terminals to base timing and set accordingly. If timing is correct and there is still a miss then you may have a prob... tps... distributor..... wrong grade of fuel... jump timing....
