it's one short flash, then it stays on....

 

If no codes are being displayed when you jump the A & B terminals then it's possible that your vehicle requires a scanner in order to retreive any trouble codes. You are jumping them prior to turning the ignition ON, correct?

 

yep...i put a paperclip between A and B...then i turn the ignition...it goes on, and goes off, then comes back on and stays on...i'll have to check a couple local mechanics and see if they have a scanner that would work on this year...my normal mechanic, for my daily driver has already told me he won't work ont he car because it's too old...he did the same with my 84 Bronco and has never worked on it...so i have to find someone new i gues...thanks....

 

i installed a new MAP sensor...let it run for a while to get used to it...tried to drive and it's still giving the same problem...i have to floor it to get it moving...if i don't feather it and i just slam on it, it stalls out and pops under the hood...once i get up to speed it cruises fine...so pulled it back into the driveway and did a seafoam treatment...started it up after 5 minutes, it smoked, then stopped, but still same problem...so i tried the paperclip to see if any codes came in and i'm getting this one...21 TPS voltage was above 2.5 volts for 8 seconds when the MAP sensor signal showed manifold vacuum to be 15 pounds or more

 

i got code 21 for the TPS as i mentioned...i broke down and bought the TPS...found one at autozone for 28.00 in comparison to 70 at NAPA...disconnected the battery, changed the TPS and started it up...i still have the problem of now power until it gets rolling...pulled it back into the drive way, and checked for codes again, and i'm still getting code 21 for TPS...what's going on?...should i just change over to carb and be done with it?....

 

If you're still getting the code after replacing the TPS I would double check installation to insure it was done correctly and check the wiring for the TPS to make sure the circuit is functioning properly. It's also possible that there is carbon build up in the throttle bore that is causing the throttle plate to not operate smoothly and hang up.

 

thanks...i'm leaning towards the carbon...i cheked the connection and it looks good to me...little tight fit, but i can push it down to click into the lock...maybe i'll try some seafoam to help with the carbon....
