I have a 1995 Chevy Lumina Van, 3.1 (S) on the vin. I have had numerous problems with it and have ran out of ideas to get it running again, other than replacing the engine. I have replaced the hoses, thermostat, temperature censor, pressure tested it, there is no blue smoke, no antifreeze in the radiator, the oil is fine. we had a problem with it over heating and it went away as soon as I replaced the bypass hose. Now the last time I drove it it started to stall, then even with my foot to the floor it would not go over 15 MPH, and went threw 1/2 a tank of fuel in less than 5 miles. I have tried to get it to start since it acted like it may if I gave it some gas, then it just started to click. I cut of the cat.converter, hoping that may solve my problems, no luck. The spark plugs where rusted in so bad that they broke off and we had to use an easy out and a vacuum. I have the front three out, and am almost afraid to get the rear three. Any ideas or suggestions would be greatly appreciated.
Thank you.
