I ran a compression test on my engine (KA24DE) and the results showed I had low compression, which would explain my poor gas millage and acceleration.
Cyl#1 145 PSI
Cyl#2 140 PSI
Cyl#3 140 PSI
Cyl#4 125 PSI (A 20 PSI drop scares me)
The specification for this engine showed min of 149 PSI and a max of 179PSI. My first thought would be worn compression rings, but I want to hear what you guys think? The engine only has 70,000 miles on it. I did forget to press down the gas pedal when I did the test (Was in a time crunch and forgot) would this cause false readings?
