Car is 89 2.8 V6, Just wondering if this is normal? Not sure how much the ecm/esc bumps the timing up but my car has been running off key since checking/setting the timing. Set it base at 10, clean, markings/lineup didn't move. Symptons include loss of power and occasional ping/pop from the intake... ANy help is much appreciated, did some searches but came up with no results.

 

Did you use the mark that lines up when #1 is TDC ?

 

Ignore where the ECM puts the timing. If the base timing is set properly, the ECM will adjust the timing to where it feels is the best.

 

gotcha on the ecm advance adjustments! looked for a while for ranges on here, thanks! - so rotate the flywheel or I believe it's actually the crankshaft, the bottom pulley bolt? and when the rotor faces the #1 cyl. its tdc right? explain the mark part to me a bit i've never heard of the that, thanks. also fuel press. is at 40 (should b 45...) at idle. will do a prime check real quick and also change the fuel filter also. after about 3 hours press. drops to 20. pretty sure injectors are good, about 5 yrs. old accel. fuel pump 6/7 yrs old walbro 255lph. the info is definately appreciated towards solving my problem..

 

On the marks , you should have two or three slots in your harmonic balancer the widest mark is #1 and you want it on TDC #1 , the other marks are not needed for a timeing light .

 

So just make sure the widest slot is marked white right?

 

Yes .

 

Have you got it yet ?

 

I have the timing set right now, thanks for the help on that. Had two slots with white and I corrected that issue. Set it to 12*. Still has a random pop on acceleration though which I think is related to the number 3 plug arching through the boot onto the egr heat shield...

 

Glad you got it now get some new wires and you should be OK .
