Wife's pickup

Question: Does the check engine light work? It sounds like you have a severe miss on one or more cylinders—it could be an ignition coil or many other things. Normally this would turn on the check engine light immediately. If it’s under warranty, take it to the dealer. If it’s out of warranty, find an independent mechanic. (not a chain like Midas)

Does the problem happen some times more than others? For example after the engine warms up but not when cold? You may need to leave it with the mechanic to be tested/driven until they can find the problem if it is intermittent.
