Thats the only way to find out the problem.

Gee, All I did was flooring my car. I did a mod recently maybe 2 weeks ago I have AEM Intake put on. And Nope I didn't get gas that day, My gas is full. Thanks Virgil, I was thinking about taking it to the dealer already to get it check. Where is ECU located in celica though? Do I need to take out a bunch of stuff to get to it?

you dont need to get to your ecu to run a diagnostics, just the little port above the hood latch release. you plug a scanner to that to run the code check. go to an autozone and they will check it for free.

if its your Intake, check your vacuum lines, you may have crossed them. clean your MAF.

if it comes to your gas tank, make sure it clicks a couple of time when you put it back on. then, unplug the negative from the battery and let it sit for 10 min then plug it back to to reset it.

otherwise, just do a scan.

no need to pull the battery, just pull the 15amp ecu fuse in the engine bay junction block

if its because of the fuel cap, it takes about a day or 2 for the cel to pop up

1) Unbolt negative terminal of battery
2) clean mass air flow sensor (search for instructions)
3) recheck to see if Intake hoses are where they should be
4) bolt on the negative terminal

yea for sho...Hey the Autozone here near my house doesn't do free OBII scans...hopefully you find a Autozone that does...because at the dealers they will charge you $80bucks just to check it.
