1989 Mitsubishi Mighty Max 2.0 from North America
Great workhorse that never dies
I bought it from a garage that was selling it for the work they had done on it. It had previously been owned by a cabinet company that used it for deliveries. It is a five speed manual transmission, and had 220,000 miles when I bought it.
At about 265,000 miles I dropped a used Japanese engine in it because it always kept getting an oil leak at the rear engine seal. I keep watching the odometer and can't believe how well it keeps on running.
At 330,000 miles I was still getting 28 MPG and decided to give it a pat on the shoulders and change out all the old rotting vacuum hoses, thinking a professional garage would ensure everything routed correctly. Now it runs perfectly fine, but now gets 2 MPG. What to do and what is wrong?
It has needed a bench seat ever since I first bought it, and is so much worse now, but I'm not giving up on it. Anybody know where I can find a seat?
Other than that, the only expense I've ever had with it is I replaced the water pump at about 290,000 miles and the radiator at about 320,000 miles.
It never wants to die. I see so many on the road, and never find 'em in the salvage yard.
Can anyone advise me on the mileage problem or locating a bench seat?
Would you buy another car from this manufacturer? Yes

My husband purchased our used 1989 Mitsubishi Mighty Max, and it has been old faithful. He also dropped a low mileage engine in it. It also leaked at the rear seal. We found a Dodge Colt with the same engine at Pick a Part.
When servicing it, he has added Lucas oil with the new oil. The other advice is don't get cheap spark plugs, change the fuel filter, and check the timing.
And recently my husband was reminded of the product Sea Foam, which he added to the fuel tank, following the instructions. It now picks up speed without hesitation.
And one last note, check the gap on your spark plug, and check for fouling out of your plugs. Hope you still have your truck.

There was a vacuum hose schematic online that might helped you solve your hose problem. When you find it, try tracing the hoses. You'll probably solve your fuel economy problem that way. Some shops can get them mixed up. Check for broken water temp. vacuum sensor (underneath the thermostat housing water jacket). Sometimes there is a sticker on the bottom of the hood that has some information on it. Every 50,000 miles you have to change the timing, balance belts and tensioners. Hope this helps.
P.S. Mine had 205,000 on it when it went through a flood. I drained the engine, transmission, diff., and put a new clutch in it (didn't really need it, but the pilot bearing was bad). Greased everything. I get 25 MPG all around town. Very reliable. Got 207,000 and runs great. I'm never getting rid if it. Too good of a vehicle to let go!
