sup yall...checked my timing last night.. cuzz i havent done it in a while.. and the engine was runnin kinda rough.... so it was runnin at 8-9deg which is quite bad (???) i tried adjusting it: When I jumped the service plug and check the timing changed to 12-13deg... tried adjusting it with the distributor...made no difference... still 12-13deg... when i pulled the paper clip from service plug, the timing jumped back to 9-10 ... .
what an I doing wrong??.... the ECU wont recognise the movement of the dist.. with the service plug umped// hELP!!!! do i have to reset the ECU with plug jumped or something...??? kinda wierd... cuzz right now im driving with it jumped... lol.. just in case...


thanks... please tell me something...

 

the timing is off or something, your not supposed to be able to adjust the timing on those cars if its obd2 and has a crank sensor

 

Ecu controls timing for obd2 ludes

 

yeh i know that... but the thing is that, why does the timing change from 9deg to 13deg once I jump the service plug... its kinda wierd...

and I thought that If i do jump the plug... ill be able to adjust the timing by turning the dizzy.... clear it up for me...please...

 

anyone??

 

When you jump the plug the car goes into limp mode which advances the timing and alters the fuel and spark maps. You cannot adjust the timing. It is ecu controlled.

 

ohh... ait thats what i thought... finaly an answear.
thanks bro.

ok ok .. but then how would you time it..after replacing the timing belt...???
or is it not necessary...??? im not used to that ..im used to timing it..... hahaha

 

When you replace the T-belt you have to make sure the valve timing is dead on by lining up the cam gears etc...once this is done the ecu controls the ignition timing of the vehicle when its running. No other adjustments are needed. I fyou just replaced the belt and the car is running bad you may want to recheck the valve timing.

 

...nuhh man.. the cams are dead on..everything lined up.... i checked .... ive done this more then once before ... but never thought to time it with a light..
but then I read all these threads about clippin the service plug... and timing it like that more precisely.. but i guess thats for OBD1?? then... cuz I timed OBD1 without clippin the service plug.....im confused...

why would you clip the plug then??
uhh..

but thanks for tryin to clear it up for me cb7-R....
