Question about Cars & Trucks
It sounds like its running on three cylinders and uses 10 times the gas its suppose to but the leads are fine and plugs are fine, ive been told it may be a worn valve could it be anything else?. it still drives but is slow and sounds like a lawnmower please help.... thanks.
It could be distributor cap they get electric arking on inside terminals and probably need good scrape of. Or a new cap and the rotor probably needs a sandpaper. To check if valve is stuffed borrow compression tester it will tell new straight away if its a internal engine problem chances are its your dizzy 9 times out of ten its electrical and just needs agood sand paper

You can try cleaning the EGR valve and passages with Seafoam. A bottle costs just a few dollars at any auto parts store or discount store. With the engine running, squirt/spray it in through the brake booster hose, or through the PCV hose. This will cause smoke to come out the exhaust. This is normal and will disappear after a few minutes. If Seafoam does not do the trick, then you can still disassemble the EGR valve from the throttle body and clean it with throttle body cleaner.

Sounds like you are pretty knowledgeable with the maintenance. With that said do you know if the Engine Coolant Temperature Sensor (ECTS) has been replaced? I'd put that at the TOP of the list of parts to replace next. If it hasn't been replaced it is the cause of a lot of problems.
The factory one is plastic and cracks. When it cracks it sends the PCM a signal that the engine is -40F below zero. The PCM will compensate by dumping A LOT of fuel into the engine to try and warm it up. It will cause all kinds of starting and idling problems.
Autozone or the dealer sells the better brass tipped one. The ECTS is located just under and behind the upper radiator hose. You'll need to remove the air intake tubing to see it or get to it. It has two wires going to it and goes into a connector. Squeeze the connector at the "ears" and it will come off. A 10MM DEEP well socket will take it out. Swap it quickly because some coolant will come out (a couple of ounces). Hand tighten it and snug it with the socket (not too much because it will strip out). Connector back on (either direction it's non polar). Put the intake back on and enjoy better starting and idling.
