Hey all. Any help here would be greatly appreciated. I have a '92 Dakota with the 318 that misfires on acceleration when the motor is cold. The problem seems to fade once the motor warms up.

So far I have replaced the air filter, computer, crank sensor, distributor cap/rotor, PCV valve, plenum gasket, spark plugs, thermostat, and wires. Could it be a clogged fuel injector? The spark plugs are brand new, so I would doubt there's any oil in there. Any suggestions? Thank you!

 

Check for codes. Look at the FAQ page if you don't have a code reader there is a manual method with the key and link to the code meanings.

 

Thank you for the suggestion. I threw a code 12 and a 14. The 12 makes sense since the truck was recently worked on.

I guess I'll be purchasing a new MAP sensor!
