hey guys,
i dont know if this was brought up or not but here goes. ok. i got turned on to this site by my buddy. it is a ODBII engine code/monitering system. from what i read it also works with ODBI cars. i dont remember which one our cars are. u can buy it from they dude that runs the web site for 98 bux or u can download the schimatic and the windows/dos based program and build it your self for prob. bout 60 bux (one of the parts u have to order from him. but over all it loox like a worth while investment. http://obddiagnostics.com<----is the website. take a look im def gonna build one. havent had a good challenge in a while.
hope this helps some of you.
