What is the proceedure for setting the timing on a 94 accord 2.2 non v-tec engine ? I was looking in a haynes manual and they were talking about plugging vacuum lines and running a jumper wire on the diagnostic wire before you put the timing light on it. Is all this really necessary ? When I replaced my timing belt I was a few teeth off and a shop charged me $23. to check the timing. They said I would have to take the belt off again and put it on in the correct timing. They adjusted my distributor all the way to one side to compensate as much as possable. I have since redone the timing belt and now need to set the timing correctly. I could use a timing light also for my camaro so thought I would buy one and time it myself.

 

you need to jump that connector or else the computer will "undo" any adjustment you make, since it will modify timing so the engine runs stable, this sets the "base" timing, which is the actual mechanical advance of the distributor itself, which is why you turn it to adjust timing. Once base timing is set, the computer will add/remove timing depending on running conditions. Too much timing and it will knock. Too little timing and it will stumble.

 

Make sure your car is fully warmed up as you need the car at regular running rpms.

 

I think you need to take that haynes manual and use it the next time you build a camp fire.
Simply, you start the car, let it idle til the cooling fan kicks on.
Turn car off.
Behind the glovebox are a couple of blue connectors, one will have two wires, pull that connector out of its storage socket, with the car turned to ON jump that connector.
With the timing light, aim the light at the front cover, you will want the RED marks to line up with the pointer. The white is TDC, RED is correct base timing.
Set timing, turn off car, pull jumper wire, reinsert blue connector into its storage receptacle, and drive on.
