Thread: Turbo gurus look; Stumped- help please

Tell us then, what have you not tried?

good luck finding your problem man.
i read the whole thread but I would not be any help to you.
Id just go get the car retuned, install that wideband and go from there.

Its funny, all that time spent rewiring, installing/removing/re-installing injectors, new ecus, etc. You could have installed 7-10 widebands already at a snail pace..........

And the excuse about widebands being sensitive is non-sense!! That "sensitivity" you speak about ties with with accuracy from a certain stand point.

Also, if you heard they were sensitive, why bother buying one in the first place?

Your argument against installing a wideband and dancing around this issue makes no damn sense...........

Good luck either way!

I would check to see if your injectors are high or low impedance. If they are low put some resistors in there and see how it performs.

have you pulled the plugs after trying to start to check their appearance?

Have you done a boost leak test?

have you tried a voltage drop test on the ground wire at the MAF? should be as low as you can get, less than .2-.020v. hopefully you can get it down to or under .008v...

I tried everything. This is why I posted up here.

what was the maf voltage at idle?

EXCEPT installing a wideband..............

1 bar = 14.5psi. So at idle with the vacuum hose disconnected your FP should be 45psi.

Since you have a Consult cable, you've verified that there are no fault codes? Have you tried turning off individual cylinders to see if perhaps you have a dead one? How do the maf, tps and cts readings look? Is the o2 sensor oscillating?

What Consult programs do you have? If you'd post a log of it idling, and then throwing some revs at it, we may be able to help more.
