With the 86/87 ECM you need an 86/87 MAF or Translator. Also the car will throw a code (turn the SES light on) if the IAT sensor wire was not ran or hooked up.

X2 . . . Unless he specifically asked not to have it installed in the chip.
(Still unsure why anyone would not want to read temp )

Can you explain what you mean when you say throw a code?

"Throwing a code" means that it will set the ses light on.

o ok got it i thought they ment it will blink a certain amount of times. So a 84/85 maf will be good as long as i use the translator correct?

If you use the stock MAF, you can not use the translator.
The translator is only used with the newer style MAF's.

You can make the service engine soon light flash and tell you the faults codes the ecm has stored, you have to trip the computer into diagnostic mode and it will flash the codes, give me a minute I have to find the link to the page that tells you how to do it, all you need is a metal paper clip or 3 inch piece of wire to jump the proper terminals on the analog hook up thats on the left of your radio under the dash and the page I'm gonna find u the link to shows u a picture of it too. hang on.

ok here it is

diagnostic mode / trouble codes
