Sup,
I have a 90 GT and its running really rich as of late. When I say rich I mean you can walk behind the car and pass out at idle or for those unlucky people driving behind me at a stop light. Anyways, what could the problems be?
I thinking I may have to replace the O2 Sensors. Anyone know a sure way to fix a rich running car?
Thanks in advance

Im tryin to get the car smogged in the next week or 2

Dump the codes and see what the computer says is wrong…

Here's the link to dump the computer codes with only a jumper wire or paper clip and the check engine light, or test light or voltmeter. I’ve used it for years, and it works great.

Lok for codes 41 & 91 for bad O2 Sensors

Ok I pulled the codes....but im having trouble reading them. Luckily I taped the codes being dumped with my digital camra. So if anyone is willing to peep at a 7Meg video of my codes being dumped it would be helpful.
Thanks

do you know where the fuel regulator is? if you do, pull the vacuum line off of it when it is off and smell the line. if the line smells like gas then you nedd to change the regulator.

OK guys
here are what I think are the codes

22 and 12

22 MAP (vacuum) or BARO signal out of range - MAP
12 Idle Speed Control motor or Air Bypass not controlling idle properly (generally idle too low) - ISC


any advice?

If you have a code that says map sensor that is your problem.Fix it fix your problem with the idle code too.You always fix 1st code 1st and follow oder given.The 1st usually fixes the rest.They are the result of the 1st code usually.When my sensor like that went it ran so rich the car would barely idle and ran super rich.Make sure it isn't vacuum to the map sensor 1st.Its on the firewall next to the vacuum tree.
