OK so i got the SR in and did a compression test. 90.90.90.30 wot and coils off. before i did the compression test, i started it up and it was missing. #1 coil was missing so i swapped with #2 coil, but #1 was still missing.wtf then i did a compression test. 90.90.90.30 wtfff??? is it possible for the sr to start with these #'s? and when i swapped coils #4 started missing. i guess the next thing i need to do is leak down. i didnt do it cuz i was too pissed off. any suggestions. o yea i put a cap full of oil in each cylinder the cylinder with 30 jumped to 60..im guessing my rings are done. but MY question.. is it possible for the sr to even start with these numbers??? after i put oil in the cylinders i drove it about 20 miles to get home. it ran rough. but it did get me home. is there something im overlooking?

Yes it is possible for it run with 90psi across the board. A friend of mine had a similar problem like this with low compression on all 4 cylinders and the motor ran pretty decent.
