Oh wow.....I've got a 13K car that I'm gonna have to do valve job on because it has a sticking valve. Bent valves aren't usually a problem because the B series engines are non-interference engines.

Yeah, I ran some compression tests and was getting 80-90PSI on all cylinders. My grandpa taught me that if you put a little oil in the spark plug hole and run compression tests again, if it's better then it's bottom end but if its the same then its top end. Well, when I ran the tests again with oil I got 120-130PSI which according to the FSM those numbers are still within the operating range. So I'm going to re-ring the pistons, do a head gasket and maybe get the block resurfaced. but so far, those are the plans for the capri. I hope I can get this thing running again, these little cars are so much fun and addicting.

By the way, is there anything on the FSM about torque specs and how to remove the head? I’m gonna need at least the torque specs.

Warm or cold engine?

[CapriManxr2]

The engine was cold when I ran the compression tests

[Rocketman]

Those numbers should pick up significantly on a warm engine, probably closer to the oil'd numbers

As I recall my healthy XR2 engines also comp'd ~90psi cold
XR2 engine is stupid low compression from the factory, 7.9:1

Geez, then what could my problem be? The mechanic said compression, I’ve done a new coil pack, got rid of all vacuum and boost leaks, new distributor cap, new engine coolant temp sensor, cleaned out the IAC, new MAF, tested the alternator and my problem still persists. The throttle response is still very bad, and it eats up a ton fuel. What else could this be?

Did you ever check fuel pressure? How about the injectors?

[CapriManxr2]

Yeah, I’ve done so many things it’s hard to write them down, when I ran fuel pressure it would idle at 39PSI and when I gave it throttle it jumped up to 43 and right after letting off the throttle it drops to ~28PSI. I cleaned and tested the injectors as well. I also checked to make sure the timing marks lined up on the crank pulley to make sure it didn’t slip out of the correct timing.
