how do I check for codes on my 93 t/a?

Beings it's still obd1 do I still jump the terminals?

thought 93's weren't obd1 and you had to jump them to get codes to flash the SES light.

don't know. That's why I'm asking. Kind of confused on the whole deal. They still run off prom chips right? IF they do I would think you could still jump terminals

http://www.fastbird93.com/Diagnostics.htm check ur codes there

I publicly thank you shoebox! I know this isn't the first time I've got info from you or your site:cheers:

Can't wait to see what that pesky code is tomorrow:LS1LT1flag:

There are also code descriptions on my site. Just make sure you scroll to the right to see the ones for 1993. (link in sig)

I was thinking beings my air pump is unplugged it could be the cause of it, but I've had that unplugged for over a year and haven't had the ses light pop on until now, it comes on every time I drive it. I find it hard to believe it would be a wire or the ecm. possibly a relay?

according to the diagnostic aids on the link, it's most likely emissions related. I have no scan tool to activate commands to check for these. I'm guessing by the time I take it to a shop and have it fixed I could probably find an aftermarket pcm tune for the same price with this crap deleted out of it???? I read somewhere the stock tune is way off for these cars, too much timing or something like that. ANy truth to this?

wait I forgot, don't the 93s still have a chip?

Yeah we use chips, there are 2 people that know who burn tunes for us.

I would like to know who to go through to get one. Would be cool to score a used one!

Well there is pcm4less.com and madtuner.com

They burn chips for us oddball 93 guys.
