I had just changed the head on a 90 turbo and now that i got it all together cylinder 3 and 4 are not working. i checked the fuel injectors and it seemed like the two from 3 and 4 were not working so i switched it with another cylinder. than i checked to see if it made a difference, but it didn't. Cylinders 1 and 2 are the only ones working . So i did a compression test on it and these are the results
cylinder 1 - 114
cylinder 2 - 120
cylinder 3 - 155
cylinder 4 - 160

When i had taken the plug wires off of 3 and 4 the engine didn't even flutter. I have spent some time trying to figure out what the problem could be, but i am out of guesses for now. I would appreciate any help.
 
Its about time for a rebuild. Those numbers are pretty low. Get a leakdown test to see exactly where its leaking from.
