Great fourm,lots of usefull info here.Here it is,1989 350 TBI that gives me a MAP sensor code,when i jump A/B on the data link under the dash.?a blinking lite,stoneage but it works.ive picked up a HAYNES Manual with the error codes for the blinking dash lite?i get a MAP code or so i think it is after replaceing that sensor 2 x its not the MAP switch i dont think.so replace the O2 sensor-coolnt sensor-IAC-ect.i still have a prob.this what the ENG does,when hot and i pull up to a lite it well chug like it has a hirise cam in it(diesle) untill i just touch the pedal and and it will smooth out,idle.the code i keep getting from the ECM is 3blinks x 3blinks and in the HAYNES manual it says for 87 only MAP switch,so any one know just what that code is? i just get the one code from the ECM
THANKS
