Ok, my engine is back to running on 2 cylinders.

A month ago, I had the same issue: very weak spark on 2 of the cylinders, then cleaned the grounds & the problem was solved.

Last week, same thing. Car ran on 4, then on a restart (after I stopped off at the gym), only runson 2 cyl.

Re-cleaned all of the grounds, verified no voltage (noid light) on the two suspect injector harness connectors.

From a diagram I saw online this weekend, I suspect one of the injector drivers as if one of them failed (there are two), it would take out the two cylinders I"m having issues with.

How do I test to see if this driver is indeed dead? I plan to check resistance from the driver through the harness to the connector too (this week).
