94 Dakota stalling/performance issue

[stealtharsenal]

Hello all,

I have a 94 Dakota with a 318 and 61,000 original miles and I am currently experiencing two problems that I can’t seem to get a straight answer on. My first and foremost problem is a stalling issue that comes and goes and a performance decrease. Basically what occurs is the truck will idle fine for a while, and then all of the sudden it will start sucking in a lot of air through the intake which is coming from the idle air control valve, smells very rich and stall out. I have changed out my Idle Air Control Valve, but that hasn’t solved the problem. I have changed out the MAP sensor with a MAP sensor from another Dakota without any avail. I have also installed a new EGR Valve. Now, I believe my performance decrease may also be related to the stalling issue. In reference to my performance decrease, the truck has an erratic acceleration meaning the truck will accelerate quickly and then there will be times when acceleration is very hard to acquire. I do not have any check engine codes except for code 37 which is part throttle unlock solenoid driver circuit. (Could someone shed any light on what that is as I have no idea what that is?) The truck is getting 15.3 mpg.
