ok so i just bought a 95 ex coupe w/ 198,xxx miles on motor n body...it doesnt run...so i did a compression test...cold engine and @ WOT....cyl. 1 has about 80 psi, cyl. 2 has about 80 psi, cyl. 3 has about 150psi, and cyl. 4 has about 150 psi...so wat do u guys think...bad motor...ill do a cylinder leak down test tommarow

 

Sounds like a bad head gasket between cyl 1 and 2 but it would still run with this problem. When u do the leakdwn listen for air escaping from cyl 2 when u do cyl 1 and vise versa.

 

so wat are the compression specs for a good healthy d16z6 motor

 

150 sound kinda high for an old motor but it should be around 140-150 maybe a bit more.

 

ok so i did a cylinder leak down test on all cylinder....and find out theres no leakage...kinda werid since cyl. 1 and 2 only has about 80 psi...then i decided to redo the compression test...and cyl. 1 is now @ 100 psi...and i didnt do a wet compression test yet...aniwais back to tryin to start the car...it has compression(enough to start and run)...it has spark...but i think theres no fuel....fuel pressure is there around 35-40 psi...so wat do u guys think...injectors??

 

ok finaly got the damn car started...and it runs fine....i found out that the ignitor module was goin out...spark was weak...then the cap bolts broke...freakin rust...ahha aniwais i was lookin around my garage...i knew i had one somewhere....then 45 mins later...i found it...and slap it on...try crankin it...it wants to start but damn it doesnt...took spark plugs out and they were fouled/flooded...so i took them out n clean them w/ brake cleaner...put it back in crank....crank....crank.....crank...about to start...its coming....bammmmmm it started...smoke like krazy for a bit but o well it started.....

 

I think my ignitor or coil is going out too...at times my tach will swing wildly from like 2k to 8k. Mostly happens at steady acceleration...

GJ!
