For what ever reason, those engine go through cap and rotors, I don't know the actual reason why.
I like to use castle hydroblast. You spray it into a vacuum line such as the brake booster line if nothing else is accessible. Full spray for 3 minutes, stall the engine with it or have somone kill it while your spraying. Let it set for a few hours then take for a short drive in low gear, revving the rpms to help break it up. First use Castle cleansrite to clean the throttle bore. Try to get the throttle plates scrubbed good with a brush, while your spraying. Use a rag to wipe the carbon out between brushngs. Seafoam is another good product, but smokes a lot.
Changing the sender again, may still not tell you the real pressure, saying the gauge is bad or there is a ground problem. If you're going to try a different one, be sure the connector is clean. You may be able to test the gauge with a test light, but being a service writer that like clean hands :wink:, I can't help you on that.
