1990 Mazda B2200 Base 4 Cyl 2.2L
What could make the truck run so badly?
The truck idles real low. Has no power and when I finally get to 50 on the freeway after 3 miles. If I give it gas it will slow but the engine sounds like it wants to go. Help please.
Not enough to go on, too many possibilities. Clogged cat, bad distributor. The Mazda 2.2 back then had a common fault. Inspect for a worn crank shaft keyway that causes retarded valve timing, Kind of like a jumped timing belt but when you check the belt alignment it will look OK unless you confirm that the keyway did not slip. That may require removing the T-belt and looking at the crankshaft gear play and keyway lineup. The keyway wears and then turns at an angle or even sideways and causes the gear to be off by several degrees. In some cases it cannot be fixed because the crankshaft wears out too much and even with a new keyway the gear fits loose. Heh, at least take a look or suggest this to your mechanic. I dealt with this at least twice on the 2.2
