Need Help, Car's computer messed up

Hey everyone I jsut recently took my 1994 V6 Firebird to have it's fuel injectors cleaned because I sometimes smell gasoline and the car acted like it wanted to stall sometimes at red lights, well I had them cleaned and the guy at the dealership liked my car so he ran some simple tests on my car. He founbd out the computer in ym car has 6 different codes somehow and he said that is what is attributing to lal the backfiring I get when trying to stay at a steady speed, as well as my transmission shifting dumbly sometimes. I was wondering if I can have my computer reset rather than going and buying a new one and having it put in, any help would be greatly appreciated, thanks.

Yea you can get the codes cleared and if thier is any updates for your computer have them put them in too. not to mention the gasy smell might have been the O-rings(2) around the injectors goin bad and leakin gas. also the updates might take care of your tranny problems. it helps when u kno what the codes are for also.

Also my car backfires a ton when i try to go a steady speed, and it idles real bad when i try to just og at a steady speed rpessing on the pedal, but when cruise control is on it backfires less and it doesnt idle real abd at that speed, I'm thinking the O rings prolyl are goin bad but I wonder how many of these prob;lems can be caused by my car's computer and the O rings, hopefully all of them but I don't know.

I just went today to autozone to have it tested and get the codes, and they said they couldn't because they codes didn't flash, so I will jsut have to wait until tomorrow and call brandon (the guy who originally said those codes were there) and see how he got those codes or what he did to get them.

The reason Autozone cannot get the codes, is more than likely, that the codereader is an ODBII, 1994 vehicles are not. You need a professional code reader like a Snap-On or the like, or you may be able to get the codes by shorting out the test plug wherethe code reader goes. I don't know about GM, but shorting the test wire on a Ford will give you a flashing code on the MIL light.

Actually they had an OBI but it was just this little piece of metal they used and they said it should flash the code but it didn't doesn't really matter at the moment because I am going to maryland to work with ym dad for the rest of the summer, should come abck with around 600 dollars and I will just get a full diagnostic on the car and find and fix all the problems then run it through e-check and get the plates and all.

i didn't think of that... the 94's were a weird crossover year where they had the obdI plug, but not the self diagnostic capability... (just dealt w/ that on a 94 century) once again, check your fuel pressure...
