1994 Mitsubishi Mighty Max Repair Question
Runs rough need help
Lets see what we can do.Is the check engine light on also I saw all the things you replaced and still doing the same thing.So it could be allot of different things when it is an power problem as you know you just have to try and eliminate things.I would start with checking your vacuum lines and make sure you don't have a leak. It is strange you keep seeing the spark jumping also would check all grounds to engine.The other thing is does it idle ok or is it seem like it is missing. I will look up your car and see if there is anything in Mitchell.
no the check engine light is not on . i just cranked it up a hour ago and its a warm day so it stayed idleing. when its cold it takes a while to get it warmed up enough to keep cranked .yes it fells like its missing when you try to drive it you go faster by not pressing the gas pedal.
I just want to make sure I got it all, so it is hard to start and when it is running it has no power and runs rough.I will look up on Mitchell and see if there are any tsb,s for it. If you have access to a scanner you could check the sensors it sounds like it could poss be the idle air control or something with the fuel system seen how you have fix the ignition problems, also have you check the fuel pressure.I know it is hard if you don't have access to a scanner but that is the best way to see what the motor is doing.
it doesnt have a place to attach a tester. how can i check the tps and ips could it be the fuel regulator and how would i check that
I will send you the chart for testing let me load it in.
will you be able to load it here or do you need my email
Send me your email tried to put it here but wont go thru
I am working on it trying to import it wont let me copy it so just give me a minute
It wont let me copy the text so I will give it to you the best I can also here is pic of it hooked in make sure to check for leaks
1 Connect fuel pressure gauge with adaptor between fuel delivery pipe and high pressure hose.
2 Start engine and let idle. measure fuel pressure with vacuum hose connected to fuel pressure regulator.record fuel pressure readings
see if this helps
