need to know what other computers will interchange with a 1988 dak v6 tpi motor with A500 trans? checked the search maybe not asking right, if someone knows can you help? thanks

 

My guess is possibly 88-91 V6, they all had the same TBI injection. But I don't know if there were any changes in wires ect. Best place is go to your local dodge dealer they can look up the part numbers. Look up those years and see if it is the same. Autozone or Napa may even have the part numbers listed on their sites.

Also most junkyards have an interchange list, check with them.

 

autozone has one for $109, but of course if that isnt the problem can't just return it. I found a salvage yard with one,they want $60 and if it doesnt work i can take it back. salvage yard is from a late 87 with the v6/a500 2wheel. this thing fires up goes to high idle for about 5 seconds then idles down runs for about 20 to 30 seconds then dies if i rev it it will run but with a surge. I'm thinking that the plastic bucket type thing that the fuel pump sits in may have a blockage in the bottom and it just can't keep up with the pump. I'm going to jump the relay to get the pump to run and see if it's just running out of fuel if the tanks not full.

 

Sounds like maybe a vacuum leak. As far as I know 87 is carbureted, so the PCM for it probably controls timing.

 

the 87 had a carb and the 88-91 was injected at the throttlebody, that may be the problem. just make sure the computer is off an 88-91.

the 87 computer does not control mixture,the needle valves are factory set, then they put plugs in the carb so there not adjustable (i used to drill out the plugs and adjust them) but on the 88-91 the computer does control fuel/air.

the reason all car companies plugged the needle valve ports when they had carbs was because mechanics where screwing them in too tight during adjustment, there only made of soft metal so it was easy to deform them and that would effect the fuel/air.
