Have Transmission Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose).
Is this a single buck/jerk or can multiple ones occur like the engine has the hiccups?
What liter engine?
Thanks, ***** ***** fit a weak ignition coil that is not getting the spark plug to spark intense enough to ignite all the fuel under this particular load. If you can make it occur enough the check engine light will eventually come on and tell you which cylinder is to blame. Another option is a scan tool that can run a power balance test when the issue occurs to see which cylinder drops out. Another option is mode 6 data to see misfire history. I am 99% sure its a subtle intermittent misfire. Normally on this engine that is a coil to blame. If it is in need of a tune up I would do that at the same time.
Now that I have posted a partial or complete answer, you will see you can rate me. The deposit you have already paid is not transferred to me until you rate me. I would like to receive nothing less than 5 star excellent ratings. So if we are not there yet, please reply and let me help more. If you're not pleased, let me know because rating bad does not result in a refund, there are better options. Rating now will not close this post nor prevent replying. Thanks Chris
