Question about Mitsubishi Cars & Trucks
Bought a Colt Rodeo. When accelerating the bakkie 'jumps' as if it loses power and gets it again. This happens heavily at 4000RPM. Both heads were redone to fix the problem - no use. Checked the plugs - all fine Checked the plug wires - all fine Checked the electricals - all fine Replaced fuel pump - no luck. Also has a ping on the valves. PLEASE HELP - this is only costing me money now.

My was doing the same thing, it was an EGR valve and a misfire on the #2 cylinder which required a new spark plug and a coil pack

before you drop tank again, check fuses & relay.then disconnect fuel line @ filter turn key to on position should hear fuel pump run and get gas stream out of line. if no flow from line new pump faulty be sure & remove negative battery cable first good luck.

sounds like a clogged fuel filter. you need to have the engine pressure checked for leaks, you can rent the pressure checker at autozone, it connects to ur radiator and u pump pressure into the cooling system if u find water leaking around the head u know u have a blown head gasket. if ok then check the cylinder compression should beable to rent this also. it screws into the spark plug holes has a gauge on it. alternator problem w/ the light is probaly you need to tighten the belt.hope this helps!!!

Testimonial: "thanks very much. i'll check that out."
This is kind of a long shot but if it is difficult to start after sitting all night but then starts just fine during the rest of the day then you may be just a pound or two low on fuel pressure. This engine needs a minimum of 60 psi of fuel to start properly. If you have only 59 psi it will crank and crank and finally start but will behave all day long as if nothing was ever wrong. You could also have a leaky fuel regulator or injector that is causing it to be partially flooded when you attempt to start it but usually those problems bothers more after the engine is warmed up. Even some new fuel pumps won't put out the needed 60+ psi and sometimes the fuel pressure regulator can go bad and not allow the pressure to build up to the 60+ psi range. The only true way to know for certain what the actual pressure is to have someone test it with a very accurate test gauge. Hope this helps out a bit and good luck.
