eco giving 19mpg

[clutch1]

I would think autozone would rent out oscilloscopes... it's such an integral tool I'd be a lil disappointed if they didn't.

But hey, I did indeed get like.. 4-5mpg better when I changed plugs. Went from just barely making 20 to just barely making 24.

Can't really comment on the catback/ low backpressure... but did ya mess with the manifold at all that would make it leak pre-o2?

If it's a decent shop they should be able to give you a pretty good estimate of what's wrong after maybe.. 30 minutes of diagnosis. I would make sure they do that first off. Cleaning injectors is a good thing for sure, and won't hurt a bit, but if I were you I would make sure they find the exact, instead of just good guesses.

Also, does their injector clean include decarboning the intake? Good ones do, and it helps a lot!

I never touched the manifold. I had a shop weld everything up, and I don't see why they would have gone that far up the exhaust.

i'm using the gm/gmgoodwrench dealer here, so they should know...

ok, o2 sensor checks out ok.

having the injectors flushed.

injectors been flushed, car seems smoother and accelerates faster. will keep track of miles and update.

window mounts broken, fixing would cost 700+, but they told me to take it to an auto glass place that could do it cheaper, am doing that tomorrow.

[darksobsession]

window was fixed for 150.

o2 sensor ok.

flushed injectors, now the car is accelerating faster, is smoother.

still getting only 18mpg.

what's up w/this?

[cherrington17]

you car is possessed.

your tires aren't completely flat? hmm... gotta get ion to check this out.

[darksobsession]

[heineck]

Any fuel trim numbers for me yet?
