Thread: Cyl #4 No Go...

Alright did another compression test, this time with throttle at WOT... same numbers.



Now I found one thing interesting, Cylinders 1-3 were dry after compression tests, but cylinder #4 was starting to fill up with fuel. Looks like you are right on the leaky injector too...

try another tester hopefully its not reading the right numbers

Eh, that means I gotta buy another one

rent one at autozone

I was gonna ask if they allowed people to rent them hehe

Don't be discouraged. My compression tester from autozone said I only had 100psi on my VET. Car runs too good to be that low on compression. The starter was going bad and barely cranking the car over, even without the plugs in. I am sure with the new starter i am about where you are on compression.

Also, you could try a diff compression tester. On my old DET I had 140psi after changing the tester. Before it was only 120 like what you got.

No worries though as long as they are all even and the car runs fine.

That's basically what was mentioned to me, as long as they are not huge differences between cylinders it should be fine. I mean the car runs 10000 times better then it did with my sludge monster. My low end torque is much better then before too

My ECU is coming in on Tuesday, hopefully I can have it running by Wednesday :-D. After that we'll see if Cyl #4 still missfires, if it does then new injector here I come haha.


Off Topic: Coheed, you had a DET? What made you want to go with VE then?

I would not recommend purchasing a rebuilt injector.
If you have one injector failing, normally the others are not far behind. Get a good used OEM set.
You could probably find a set of injectors in the forum Classified section.
Heres a nice set for $100.

Purchase a set & have them sent directly to a injector cleaning/testing shop.
I use Tim @ Clean Injectors. They are fast and the price is reasonable.
That way, you can start out with a dependable set of injectors with all new seals & pintals.
Then use your old 3 remaining injectors as backups for future failures.
Just my .02

I might just do that hehe, well I'm about to pull the fuel rail off again and see if it's leaking again (could be a bent fuel rail)

pics of your motor in your car of ban... escuse me if you already posted them lol
