Truck died while at the stop sign. 88 Dakota 3.9 V6 automatic
On the way to work this morning, my 88 Dakota 2WD 3.9 V6 automatic died on me. Got it cranked back up and going. Sounded like it was idling high. I had to slow down to make a left hand turn at the green light and the truck died again, so I coasted off to the side of the road. Put it park and fired it back up & it sounded like it was idling high again.
The gas gauge showed between 1/2 and 3/4 of a tank of gas.
The last thing I done to this truck was install a new fuel filter and replaced the two rubber hoses on the fuel filter.
Any suggestions?
I did need up replacing a missing vacuum line from the front of the throttle body to the air filter. A friend & I replaced the IAC last year & used a tachometer to set the screw. While in idle, the truck revs up & goes back down as if it’s about to die, but if I push the gas pedal, the truck makes a loud shrill noise.
My next concern is, should I replace the intake manifold gasket?
ECT - sorry. Engine Coolant Temperature sensor. You're supposed to disconnect it, which causes the ECU to pull all timing. There's a sequence to it, covered in the FSM.
I figured that's what you meant. Here are two pictures from the 1988 Dakota Service Manual from Chrysler Motors says:
