I have a 98 Honda CRV that had P0104 and P0103 and P1399 codes. I replaced the plugs and wires with no change. I performed a compression test on all four cylinders and results seemed fine.

Compression Test Results:
Cylinder 4 - 160(Dry)/200(Wet)
Cylinder 3 - 150(Dry)/185(Wet)
Cylinder 2 - 145(Dry)/190(Wet)
Cylinder 1 - 150(Dry)/160(Wet) I think i used less oil in this test then the rest

I just replaced the Distributor Cap and Rotor and have yet to see it throw the P0103 and P0104, though when i pulled my Codes i got a Pending P1399. The timing is spot on. I also did a spark test and i do see spark on the wires.

I dont think the valves have been adjusted so i might need to do that.

I also tested the resistance on all four injectors im getting about 12 ohms on all of them.

Any suggestions?

 

Does it run poorly? Have you ever had a valve adjustment?

 

It runs good, it does not stutter at all, i dont think the valves have ever been adjusted but im not totally sure.

 

You need a scanner with datastream. Then lets take a look at the data stream. A 98 is early obd2, but there may still be some data that we can use.....

 

Cylinder 1 exhaust valve(s) burnt up. Common issue.
