I went to advance my timing. I hooked up the jumper wires and the timing light sensor to the cylinder furthest away from the distributor(usdm driver side). I turned the distributor towards the firewall. The timing marks a lil to the right. Did I advance the timing or retard it? (It sounded like the rpm went up about 100rpm at idle)

 

advanced. you forgot to warm up the engine and jumper the ecu service plug

 

koo..yeh it warmed up till the fan came on..i did the jumper on the driver side wheel well.. thanks man

 

why do you need to do that jumper thing ? what exactly do you do ?

 

it sends the computer into limp mode. If you don't jump it, the computer will keep correcting as you turn it. It is a little blue socket above the ecu on the passenger side. Jam a paper clip in both sides (connection), and it sends the computer impotent mode.

 

on 88-89 its in the engine compartment..driver side white and brown wire i think

 

gaw i need to check mine b/c when we did it a long time ago i don't think we did the jumper wire. i though that was just for obd-1's

so i'm at 17 * advanced according to the timing light

stock 15* + or - 2 right?
