Hesitation, jolting, and missing?
Asked by Shurmantine Jun 10, 2018 at 08:33 PM about the 1999 Ford F-150 Lariat 4WD Extended Cab LB
Question type: Maintenance & Repair
My trucks been hesitating, jolting, and just feels like a
misfire but I've already changed the plugs wires, fuel
filter, I clean the throttle body and my mass airflow
sensor but I'm not sure what it is and the engine
check engine light turned off by itself so now I'm
stumped...

Do you know the codes?

It's not throwing any codes anymore but in the past something was running lean? And a random missfire
Sounds like a vacuum leak.

I've been doing a lot of reading and I've come to the conclusion that it is most likely one of the coils. I'll do the work and let everyone know what the outcome is.
