Having problems with your 1991 Toyota Tercel ?
Low compression cylinder - 1991 Toyota Tercel
Time for a new car, unless you want to spend the big bucks to repair your engine. Low compression, below 100 psi, means the cylinder will not fire, will miss, have low power. The reason could be a blown head gasket, worn rings, valves not seating properly-at the very least, the cylinder head will have to come off. Before doing that, though, do a leak down test to pinpoint the cause of low compression in that cylinder. If just one cylinder is low, and you have good compression otherwise, it may be worth fixing. Tercels are low value beaters, but I owned a '94 tercel, and I loved it, till the engine went south, just like yours-body was too banged up to make it worth fixing, though.
