I have posted this under Unhappy CJ7, but would like to re-iterate my help needed. History - 70s 350 with TBI installed in 2014. .195 intake heads, 30 over pistons, mainly stock, but whole assembly balanced with TH400. Ran great, but now lacking power under acceleration. I got the Tunerpro so I can read more than a key turn for the OBDI. I attached a log file. Idled, went down the road with mild accelerations, WOT a couple times to feel/show the stutter. Idled at a turn, geared down and WOT through 1-3. Once home, I put it in park, and idle went through the roof!
Any help of what to look at, or try next, my wife and I would really appreciate it. We love driving this Jeep, but have not been able to enjoy it for most of the summer.
Diagnosing by wallet, and some manual reading diagnosis has not panned out. I'm savvy with engines, some electronics. New to the Tunerpro, I am asking for support! Moral support if any.
Thank you for your time!!
