Another Mopar Off My Bucket List - Barracuda Fastback
Roadrunner update:
We are getting really frustrated. My son (Spencer) took his Roadrunner to Columbus, Nebraska Wednesday morning. His plan was to spend a few days there while I worked on other things.
I talked with him on the phone today and he said he wanted me to drive the Barracuda to Columbus to the opening day of FAST & FURIOUS 7. I suppose I could. He'd like us to have the Roadrunner and Barracuda parked side by side outside the theater.
I asked him how the car was running and he said it's back to it's old tricks.
Despite the fact it shows adequate fuel pressure it behaves as though it isn't increasing supply when you try to accelerate. That means that you have to depress the throttle very slowly to prevent it from stumbling badly. When he reset the ECU it ran great again but gradually the problem came back. He reset again and it worked great for awhile but again, the symptoms returned.
We had believed that our problem was due to the computer control of ignition timing. Now that it's being controlled by the MSD equipment we suspect it may have been failure of the injectors to sync with the throttle. I'm not certain that we can rule out our MSD control box yet. Even when the FAST ECU was controlling ignition timing, we were supplying the signal from the MSD box.
I guess we'll be trying to isolate the problem when we get a chance. The problems only seem to show up when we're under load and driving down the road. Maybe we can try to duplicate the condition inside the garage.
One reason why I hesitate to rule out the MSD box is we had difficulty getting the timing light to pick up a signal at times. I thought we had a faulty wire on the timing light but maybe it was actually indicating an issue with spark.
