I know you get what you pay for so I'm looking for an OBDI code reader that will work on my 1994 Trans Am. Not necessarily cheap but a good price as I can't shell out $300 for one. I can't seem to find any OBDI scanners?

I finally decided to get one because last week I paid my mechanic $182 to replace my TPS! My car wouldn't start and I couldn't figure it out, so after a couple weeks of me messing with it I took it to the shop. The SES light never came on either which is why I found it funny that he was able to pull codes? Anyway it turned out my TPS was reading over 4 volts or "flood mode" so it wouldn't spray fuel at startup. The sensor was $40, labor $20, and diagnostics was a whopping $120! Now you see why I want my own code reader?

Rather then buying a code reader, just connect terminals A and B in this picture:

The SES light will flash so many times, pause, then flash again like this:

* * * (pause) * * * * * that would be a code 35 and so forth.
Then get online and find out what that code means.

I believe jumping the terminals only works on the 93's.

That works for 93 but not 94. Trust me I have tried. Plus shbox.com also verifies this.

Do you have a laptop?

If yes just buy a cable (you can get usb or serial) for like $50-$75 and then use freescan(free) or datamaster(free for first 20 scans).

go to kragen's, $30 and comes with book to decode. the only thing is that with obd1 reader, the codes give u multipule answers to what it could be!!

I just did a little searching and found this. http://www.autoshoppingcenter.com/te.../obd_3123.html

EDIT: I guess that's the same thing that Kragens has. Kragens has it for cheaper, though. http://www.partsamerica.com/productd...egoryCode=3389

If you have a computer it doesn't really make sense to get that imo b/c with a cable you can do a complete datalog, not just a code scan.

So all you'd need is a laptop and one of these? http://www.aldlcable.com/sc/details.asp?item=aldlobd1u

that's correct.

I really wish I wouldn't have sold my laptop then. I could save a ton of money by getting a cable and just doing an email tune for MadZ28. Because, all I'd need is a laptop and that cable to do this right? http://www.madtuner.com/index.php?pa...mart&Itemid=26. That'd save me a ton of money as opposed to ordering a new PCM and having to do the core charge and worry about all that crap. Maybe I should just try and find some old laptop and get a cable then.

I use an Auto Xray that works really well. I got it off ebay for like $125. It tells you what the code means and not just the number plus you can view sensors in real time.

Would the cable/laptop way allow me to delete codes also? Ever since I got my car back from the mechanic the SES light is on. He said its a MAF code and thats probably because its descreened. It would just make me more comfortable to have that light off so I want to delete those codes.

You can clear codes with datamaster. You can program them out with a tuning program such as Tunercat. Although, you should not have a MAF code because it is descreened. Plenty of people have done that including myself and I've never heard of that throwing a code.

im in the same boat as u are pork my car runs shitty and im throwin a check engine and my buddy hasnt brought his down in over a month so im thinkin about just buy this http://cgi.ebay.com/ebaymotors/Actro...spagenameZWDVW if any one has one or any comments about it id like to hear about it

Yeah, you shouldn't be getting a code for descreening it. I don't have a code after descreening mine lastnight. I only occasionally get a code for my damn drivers side o2 sensor which is bad.

Well my car runs fine, it just idles high...like 1500 rpm's high. It comes down to about 1000 after I drive for about 5 minutes. The tune from madz28 has it tuned for 700 rpm's though. He just said my car is throwing a MAF code but every car I know who's MAF is goin out their car runs like crap. When I unplug my MAF the car runs like crap so I assume its working.

^^ yea, our cars are cool for checking MAF function. we have SD option!

Have you tried cleaning your MAF to see how that goes? My car ran a ton better lastnight after I gave the MAF a good cleaning and descreened it.

porksoda

Well it doesn't run bad at all. No stumbles or anything...ever. Just the SES light is on and I wanna find out why. Maybe has something to do with the high idle? Plus if I'm able to scan my car in the future myself then I don't have to go to the mechanic for it.
