The truck has 196,000 miles. (I am the original owner). It starts to surge/stumble upon rapid acceleration.
Gentle acceleration seems not to be a problem. It has stalled once or twice and had difficulty restarting. Two shops have not found the problem. The last shop recommended a scattershot approach (replace the coils and igniters, replace the distributor and the electronic carburetor. As these are not inexpensive parts, I am trying to narrow down the problem area. One of the coils has a very small spark compared to the other. Could this be the issue? This problem started several months ago and has become worse over time. Any ideas?
