hmmm...that damn check engine light!!

[turbo98eclipse]

welp...the c.e. light recently came on and ive been noticing a few strange things. ive noticed that the turbo doesn't spool up to full boost like it used to and when i floor it the rpm will get to around 5000 and you can start to feel the engine studder/spudder (same thing) but if i let off the gas for a sec and floor it again, itll just pick up where it left off with no problem. when i look on the dash at the stock "boost gauge", by the oil temp readout, the needle says the turbo is at full boost, but then the aftermarket gauge says its still in vaccum. i dont remember how it was before, but is your gauge supposed to read out vaccum if you are crusing on the highway giving it verry little gas? i can still get it to like 13 psi (t25) but thats only when i floor it and get to higher rpms, but i thought i should be at full boost at like 3000 rpms not 5...any ideas? and sorry for the essay..

I had my c.e. light on once but it was for a miss fire in cylinder 2. I am in an automotive class and we use a computer for when a check engine light is on. If you can get your hands on one of these it will tell you what's wrong or what's goin on. You can prob get this done at a local mechanics shop. That's about all i can tell ya good luck with it.

You said there's a CEL on, what is the code? Take it to AutoZone and have them slap it on the ODBII scanner.
