99 dodge dakota, intermittent problem. Goes in and out. Starts to bog down to 500-400 RPMS at idle, and loses power under acceleration. Pop in nuetral shut off, and turn the key back on and it runs fine until it does it again a few miles later. Threw codes P0123 and P132 which are TPS and Bank 1 02. I replaced the TPS and no luck. Still have a code for a TPS. Then i went to a salvage yard and threw an IAC at it, which seemed to help last night, the codes are gone, but this morning did it again. Really getting frustrating, any help would be great.

MAP and MAF sensors would suggested, but Im tired of throwing parts at it, guessing.

 

Sounds like a vacume leak in the system cracked vacume hose bad connector so on.

Check all vacume lines for leaks

 

Right but if it was a vacuum leak why would it shut off and start perfect everytime? Wouldn't it constantly run like crap?

 

Some leaks take time as you drive it screws up your emission controls.

You may have a fuel pump going bad low pressure in fuel line check fuel pressure.

Bad fuel pumps are very common problem on older Dakotas

 

Hay at least it cost nothing to check that's what you wanted correct.

Either its

1 ignition, coil, plugs, wires or cap

2 Fuel pump, fuel problem

3 vacume leak or emission controls

4 mechanical timing chain, heads, valves so on

Miracles we can’t perform

 

Cost is no problem i just want to know for sure what it is and if anyones had the same problem. I have an electronic fuel pump thatll fit the dakota lying around. Might throw that in and see what happens. I can cross off ignition because it has a perfect start everytime and even when it starts doing it, if you shut it off, it fires right back up and drives.

Are you able to do a trap door for the fuel pump on dakotas? (Cut a hole in the bed)

 

Most shops will look at your truck for free get them to dignose the problem take it home and fix it.

Now beware shops can be wrong on the problem just like you.

 

Shops i took it to called the tps and the map sensor. Im not too sure they know what theyre talking about.

 

try another shop Moe is headed their now!
