Bringing My AP1 Back to Life
Alright guys I haven’t been on here in a long time, and I’m trying to get my s2000 back to 100%. Here is the rundown, I took my car to InlinePro in 2017 with 99k to get my head rebuilt due to low compression with bent intake valves. They did the following:
-Installed used F22C cylinder head, intake valve set, exhaust valve set, springs, retainers, and bases
-New AP2 OEM keeper set
-New valve guide seal set
-Clean, inspect, hot tank, soda blast, install valves, springs/retainers, bases, keepers, and seals on used AP2 cylinder head
-New OEM headgasket
-InlinePro TCT modification
-Valve adjustment
The car starting having trouble again at 134k, I am dealing with low compression once again on cylinder 1, never mis shifted the car and always change the oil regularly. The car currently shows misfires on all cylinders, and has a rough idle. When driving and coming to a stop putting the car in neutral, the RPMs will drop down and the car will shut off. Constantly have to restart the car at every stoplight unless I give it some throttle to prevent it from shutting off. I am going to post every step I do to the car from here on out and hopefully get the car back up and running at 100% like an S2000 should

To try to fix the idle shutting off issue so I can drive the car to my Honda mechanic without shutting off at every stoplight, I cleaned the IACV and made sure it can spin freely.
I took out my MAP sensor and used some MAF cleaner, resecured with zip tie.
I also cleaned out the throttle body butterfly with some carb cleaner, although I will have to fill remove it to get inside the manifold since there was a ton of carbon in there
before clean
I did the idle relearn procedure by starting the car with all electronics off and holding the RPMs at 3000 until the engine got to operating temp then letting it idle for 15 mins. If I give the car a rev, the RPMs still drop down and the car just shuts off without holding idle.

Idle relearn procedure should be be 5minutes on a warm motor.

have pulled codes and diagnosed the misfire? maybe it is your coils?
can you quantify the low compression in cylinder 1?

Your profile says you are in Virginia...if that's the case PM user Billman250, setup an appointment and get your car to him.
Then enjoy worry free driving for the life of your vehicle.

Yes I’m located in Northern VA. I believe Billman is in NY? Based on my leakdown results tomorrow I’ll give him a PM

So we did a compression test earlier today.
cylinder 1- 160
cylinder 2- 60
cylinder 3- 160
cylinder 4- 160
Did a leakdown on cylinder 2 and it’s around 16psi leakdown
My mechanic is telling me it’s a dead cylinder and rings are the culprit. Note that the car has not been burning any oil, and no smoke coming out the exhaust. I’m waiting on a rebuild list from him, and would like to hear of some rebuild lists/kits from you guys as well
