1997 Dodge Intrepid P0137

Capacitor is located about 6" up the harness toward the firewall from the coil. It's shrink wrapped into the harness and is rectangular in shape.

I replaced it with a condenser from an old point type Chevy. My car has run fine since.

Cleared the code and it has not come back.

Good Luck!

The capacitor is, in fact, built into the wiring harness. The Dodge dlr told me that the harness had to be replaced to fix the problem.

To verify the cap as bad, I took the car out and got it warmed up. I then got the car in the garage, and took a hair drier and concentrated heat on the cap with the engine idling. As the cap got hot, the engine misfired and eventually died and would not restart. I cooled the cap off with compressed air and the engine restarted and ran smoothly. Just to be sure, I repeated it. Then I had to figure out what to do about it since I wasn't about to replace the engine harness.

I tried to get a matching cap from the local electronics suppliers. None had one with matching specs. Then I thought about a condenser from a point ign. A condenser is nothing but a capacitor under another name. Spent the $3 to get one, soldered it in and problem is solved.

The 137 code is a drop in primary voltage to the coil under "full dwell." This means that the primary wire from the pcm has a drop in voltage under acceleration.

My car started with a hiccup under acceleration, then gradually worsened until it shut down under accelearation, then just shut down period when I heated the cap.

Follow the green hot wire from the coil pack. It will lead you right to the cap.
