I have a 96 silverado. Truck is bucking and shaking and I have a code for a multiple cylinder misfire. I am not sure but when starting I think I smell gas.
December I replaced spider injectors, new distributor cap in January. Plugs and wires are about three years old. Truck has been running fine until on my way home last night. So it seemed kind of sudden.
I used my scanner and on face value ETC, IAT, TP all seem to be working and fluctuate as they should.
Any ideas on what to check next?
