You have to treat it like any other car that won't start.....check for fuel pressure, check for spark, check for injector pulse... It's coincidence that you JUST changed the oil, and cleaned the engine. I see it alllllll the time at work. Half of the cars that come in.....they're there for one thing...then two days later something else breaks. This is especially common on cars ten years old and more. Sad, true, GW

Very true. You fix one thing, the vehicle gains back some lost performance causing a marginal part to fail. I think that's one reason that folks get upset over tune-up prices these days. Anything that even tests as marginal gets put on the estimate and rather than view it a preventing future problems people see it as padding the bill.

We tell anyone with drivability problems and NO service records that we can't even begin to diagnose it without the $100 fuel injector and upper intake cleaning first....then plugs and wires...THEN we will scope it....but it never needs the scope after all that. GW

I shouldn't have said never....once or twice the computer was failing to ground an injector or something crazy like that. GW
