My 1994 Chevrolet C1500 with a 4.3L V6 is really loping and getting bad gas mileage. Not the EGR valve.?
Starting Saturday, my truck has been idling very roughly and making about 8mpg (compared to 16 earlier that day). It doesn't vibrate when you give it throttle though. I cleaned the throttle body, changed the oil (to Royal Purple), replaced the spark plugs with Bosch Platinum 4, checked the plug wires, distributor car and rotor, replaced the coolant temperature sensor, put cleaner in the gas, checked and cleaned the EGR valve, checked vaccuum lines, and everything else I can think of. It's still making plenty of power like it used to but it's getting about half the gas mileage and idling very rough (shaking the whole truck like a 454). It sounds like it's running on about 4 cylinders at idle. I'm thinking it might be an exhaust valve or two because the tailpipe sucks in air about every stroke (if you hold a dollar or piece of paper at the end, it sucks it in) If you have any ideas I would really appreciate it.
P.S. I recently replaced the fuel filter too.

i own a repair shop and you need to run a compression check on it and see what the compression is,it may have burnt a valve on It,or its possible it might have jumped a tooth or two on timing,all you can do is check it and see but i have found with the 4.3 engines that they usually will jump a notch on the timing chain and gears and this causes it to run rough and idle poorly but check it real good it may have slipped a notch out,,good luck,i hope this help,s.
