Car's going into limp mode..

[Herblenny]

Well, before I got the car, it had the latest flashes and such. And its so out of warrantee

regarding gas, I drove from Bham to MS without an issue (190 miles from fill up).

once I reset the ECU, everything seemed fine.. and filled up again and drove total of about 300 miles. It wasn't until third fill up and 150 miles later that it went into this limp mode.

This time I watched the cluster to see if any lights were blinking and such... NONE!

I thought it might be something to do with ignition but after reset, everything is back to normal. I could get up to 90+ mph without an issue... So, I don't think its injector..

I've heard something about gas cap issues but don't know what that does??
