I will look at the marks soon, as for the EGR, it can be disabled, but I don't have the download to let me get rid of that yet. But even if it is disabled the EGR can be stuck open, so it doesn't matter what the circuit is telling it to do.

I hope something will get figured out tonight, ill look at testing the MAF too.


EGR checked out good, we even took it off, and plugged both ports in the intake manifold with no change in results.

 

I took all the spark plugs out and checked them, they look brand new, not hard carbon built up on them, the car actually get the same gas mileage I did forget I didn't fill the tank up all the way one day, which most the time I do fill it up all the way. The previous owner, (he owned it 5 years) said all maintenance was done at around 88,000 miles.

I put all the plugs back in and started doing compression testing.

[Test results/Done cold, engine was not run for 15 hours/WOT/throttle plate open]

Cylinder #1 -148 PSI

Cylinder #2 - 150 PSI

Cylinder #3 - 146 PSI

Cylinder #4 - 149 PSI

All those look pretty good for 119,427 miles on the motor, so that is good to know. I am currently going to look at the top marks, followed by the crank mark to see if they're aligned correctly. After I am done with that I want to test the MAF for spec, and MAP sensor for spec. I do not have any weird noises when I drive, and boost seems to stay where it should.

Hope this helps anyone with my issue, I am still searching.

 

Also, I am trying to line up the lower crank pulley notch with the numbers on the lower timing cover, I cannot read those numbers though.. I think there is a 10 degree and a 0 degree? Any help would be great!


UPDATE:::::

to me if you're looking at the 10 degree you go to the right and the long line is 0 degrees, I lined that up and the top marks align as well, so it looks like the timing is now in spec too.

time to look else where now...

 

I took the IAC off, and turned it and stuff started the car and it idled perfect, then turned the car off same problem. I am sure it is the IAC.

 

did the iac move when you had it off and turned the ignition?

 

I think I can hear it, like when you turn the key off. But the car actually idled perfect after I took it off and back on, but after turning the car off.. and restarted it, the problem was back...

ideas?

 

Got a IAC (used) but lower mileage from an '05 EVO. I guess these are a lot more reliable problem 100% fixed.
