Don't even get me started about posting without telling the problem. Not being mean but give us a break... People can't troubleshoot anything if you don't give them a problem, with information.

Find out what the codes are for by Jumping E1 & TE1 in a diagnostic port. Read the code the CEL flashes & look the code up.

 

He can do this at Autozone for free right? When I was at school at U of I in Champaign/Urbana those guys are just begging to come outside and help since they had nothing to do

 

No.
It's OBD-I Toyota.

 

Check the air filter? Once I had a REALLY dirty air filter and my light came on, I bought a K&N replacement and it was alright afterwards.

 

lol cuz of broke college students. dont want to fix or maintain their car. friend of mine goes to niu. and i chewed her out because she hasnt changed her oil since shes been in school

 

DUH that's what dad is for... Seriously...

 

It can be your gas cap. Maybe it's off or not on right. Check it, unplug your battery for a few minutes, then see if the check engine light comes back on. It happened to me once.

 

Not on a '93.
troubleshoot before throwing random things around guys LoL!

 

OK... here are some things that could be a possibility...

Bad O2 sensor.
Bad Knock sensor.
Bad Catalyctic converter.
Low coolant, Over heating.

The 'check engine' light is reserved only for powertrain problems that could have an impact on the emissions systems.

 

if he wnat us to help. he needs to jump the wire and get the code...
