Thanks for the info. My truck is a '90 Trooper with the 2.8 and manual tranny. New development last night, one of the fuel injector probes caught on fire last night and melted and belched a lot of smoke out. I have never had any sort of problem with the fuel injectors until this dealership laid hands on my Trooper to "diagnose" a high idle. I'm really upset.

Additional info, the tech said I needed a new Throttle Body, cost $1,416.60, a new EGR Valve (has one that is less than 6 months old and is working fine) cost $53.00, a new Distributor (says it has excessive play in it) cost ???, says he can't even order one. And of course the new PCM.

After asking him if he guaranteed that this would fix my problem (although I wasn't really considering the work since my Trooper cost me $1,300 total), he said "it should", but he couldn't guarantee it.
