Does an 1989 Power Ram have a MAF sensor or equivalent sensor ?
No mass airflow sensors back then on hardly anything. You got a pre-Magnum 318 with a throttle body so its basically an electronic carburetor. You getting any codes on that?
it is more than a electronic carburetor by 89. you are probably thinking map sensor.
no check engine light but I haven't check the codes yet... just getting what feels like a miss fire when I accelerate...
Yeah, the truck is new to me, and im getting a miss fire when I accelerate... trying to poke around at what could be the issue
Usually not a bad map doing that.
Look at spark first.
Couldn't hurt to run some Techron fuel injection cleaner through it either.
have you done a basic tune up on the truck?
it sounds like it could be a map sensor
If you haven't done a tune up yet.
Personally, I only ever used and prefer the factory Mopar cap and rotor - the clearances are always correct and the vent is correct. Some people like the brass inserts but they don't work well in the humid area where I live - I can't tell you how many cars I have fixed by just putting the factory cap and rotor back on back when I was a Chry. tech.
Spark plug wires - the best bang for the buck are the Summit 8 mm wires, high quality, durable, great price.
Plugs - I prefer the factory spec Champions, maybe NGK's, not an autolite fan.
I also liked running either a higher output coil or a msd 6A with a stock or aftermarket coil.
Cap and plugs seemed to last longer with the MSD/stock coil combo.
You are welcome.
By Summit spark plug wires, I mean the Summit Racing branded wires they sell.
