:eek: Gas isn't a very good lubricant, how many miles did the wife drive before the car ended up dead? The problem with the IP and the injectors is that if they have been scored because of a lack of lube, you won't realize it until 10-20k down the road. And for the amount they charged you, I doubt they did a very thorough inspection of the pump or the injectors.. They probably just hooked it up to the computer and checked the flowrate of the #3 injector (The one with the wiring harness on it)..
The good thing about the engine in your car is that it's a workhorse and *should* be ok... From time to time when you get home, pop the hood and put your hand on the injection pump.. You should be able to rest your hand on it even after a long highway run.. It will be hot, but not searing hot... That's a good indication if the pump is on it's way out...
Some added protection would be to run some PowerService in each tank, or even better 2stroke premix oil...
If you have any other questions, don't hesitate to ask.
