Hello everyone, the '85-85 FB's had a CPU is there a way to hook up an OBD sensor to diagnose a problem on these models?

 

Nope it is not OBD compatable.

 

Does anyone or you, have a diagram for the homemade throttle position sensor adjuster for the 1984-85 GSL-SE. Or know where I can get one?

 

I've found the two light method to be very unhelpful. Look up the S4 FSM and follow the voltmeter procedure.

The Factory Service Manuals for all years of RX-7 (and many other rotary cars) can be downloaded for free here: http://foxed.ca/foxed/index.php?page=rx7manual . They contain all common service information and more, and are an essential tool for any sort of service work that needs to be performed on these cars.

Additionally, the Haynes service manual for the 1986 thru 1991 RX-7 (both turbo and NA) can be found at most local auto parts stores or purchased from any good bookstore (ISBN number 1 56392 007 7). It is only about $25 and is a great quick reference for things like this. Not only does it contain most of the information in the FSM condensed into an easy to read format, but it includes full wiring diagrams as well.

These manuals will answer 99% of service related questions for the car and if you intend to do your own repair work, you will need at least one of them. Preferably both, since the FSM is a free download. The Haynes is a good quick reference covering 99% of questions, while the FSMs show complete and detailed procedures.

 

Thank you. I will look for the FSM.; since I already have the Haynes 1979-1985 1ST gen. manual with the sopplement for the GSL-SE model years.

 

Thanks
