So, I could write a book about what all has happened since the DOD / AFR delete. Went to a new tuner because of the persistent hot hard start issue. He thought he fixed it but has not. however he found thing in tune that were wrong and fixed them and the truck now idles smooth and runs better. since the hard start issue started right after delete and first tune they thought is was connected. Since then the purge solenoid has been changed,(i know new doesn't mean good) and vent valve has been change neither helped.
Is there a way to test solenoid?
any ideas?
THanks
Interesting. I have the BTR Stage 2 (v2) truck cam in my 6.2 since the winter, and it has stalled once and been a little hard to start when hot a couple of times (cranks an extra second or two), but it's very rare. Idle is definitely a little choppy but I like it. Is your stage 2 cam a v2 or a v1 version? I'm wondering if maybe they had some drivability issues with the v1 version that led to the v2. Just thinking out loud. Also, I had Black Bear do my cam tune and they did a great job so I wonder if it's worth having Black Bear do a tune for you. I know it's pricey, but might help solve your issue. You could always revert back if you need to.
The only other thing rolling around in my head is the possibility that the fuel pump is on its way out. When they start to fail, stalling and hard starting, as well as throwing the stabilitrak code are some of the ways that they start talking. How many miles on your rig?
What else have you experienced since your cam swap that might be significant that's not already mentioned in this thread. Anything else I should be on the lookout for? We're fixin' to pull our camper 4500 miles in the next 3 weeks, so it's gonna get a good shakedown.
