Question about Cars & Trucks
My mitsubishi L300 van is 13 years old and the fuel pump has never been serviced manually. recently the exhaust is excessively smoking especially at high speeds and uphill driving also during shift in gears as i accelerate. ive noticed also my fuel consumption is higher than usual. i would like to scrap, service and rebuild my fuel pump in hopes my problem would be solved.
What color smoke is your diesel tractor making if you see heavy white smoke tractor injection timing off.see black smoke injection pump too far advanced or injectors nozzles need cleaning.diesel engine has excessive fuel consumption injector nozzles need cleaning or fuel return line restricted.injection pump could need to be retimed.

If it's carburetor & has automatic choke, then there is probably a screw at side of carb, by step cam that moves with choke . Back it of a little at a time until you get desired cold idle speed. Make sure you turn step cam to setting it would normally be when cold, and choke on, then turn screw out to lower rpm's. Look for a little rod from choke shaft, down to base or side of carb area, to step cam.

SOURCE: For a 1989 Corvette L98,
have you checked the EGR Valve for leakage? if it is leaking the valve will get very hot at idle right away after a cold start, also the intake manifold gaskets leak on these, it can leak under the manifold and on the top do a propane enrichment to see if engine smooths out at idle. I will bet the EGR or the intake gaskets are the problem, u also never mentioned the all important electronic engine control fault code test, go to the link for instructions on how to do this test without a scanner.
