What have you done to your square lately??

[mxer147]

Rust oleum hood underside and some associated parts. Used some enamel hardener this time.

Replaced the passenger side power window regulator. Hooked it to the newish motor and newish rewired switch.
Goes down like a rocket, won't come up without help. Worse than before.
May be time to replace the cheap LMC window track felt with the Precision ones.

Two things come to mind. Either your vacuum leak was bad enough that it affected your throttle position in relation to rpm (your trans uses rpm and throttle angle to determine shift points) or they moved the throttle bracket when tightening your intake bolts and then re-adjusted your T.V. cable.

Thanks Andy. Could this have anything to do with TPS sensor and/or IAC valve? I replaced these early on in the dive in to this all, before the TBI was rebuilt. Do I need to set base idle? Should I do the A-B port jump trick on OBD1 to get the IAC valve needle where it needs to go?...or is it too late for that? @Redfish Andrew, I know you must have a thought of what could be next here maybe? I will be checking Brian Harris' website. Think I
it's possible I could get in touch with him on the phone somehow?

I have...thoughts.
1. If it started after the shop fixed your biggest problem (it didn't run!) then it is related to either the fix or some adjustment they made. That adjustment was either accidental or intentional.
2. You were just singing the praises for this shop (as well you should) so if I were you I would start with them. If they found something that none of the very knowledgeable folks on this forum suspected, they must be pretty good. Bring it back to them, let them ride with you or drive it themselves. See what they think. It may be something simple, it may be something expensive. But if they can make it run correctly they can probably make it shift correctly.
3. I am still just super happy you got that beautiful truck running again so I have not focused on your shifting issues as a priority. Sorry for that.

@Redfish Andrew, https://harristuning.com/Tbi/recommended-350-tbi-mods/ does have a lot of info on these systems as you have told me. Maybe this goes back to my exhaust as well...
@bucket Andy, have you ever seen Brian Harris' harristuning.com website?

I am stoked it is running for sure don't get me wrong. Sound advice as always. I'm sure they would oblige a ride along to experience and go from there. Thanks Andrew!

Sorry, @JamesSam forgot to answer that part. I don't know about getting him on the phone. He and I communicated by email. He sure knows a lot and he helped me out big time...but he seems like he doesn't enjoy communication. I may be wrong on that but that was my impression. Again, my experience with him was very positive.

TPS position only affects TCC lockup on a 4L60 with TBI. Shifts are very much controlled by the TV cable. I'd ask the shop if they made any adjustments to it when they tightened the intake manifold.

It's been 10+ years but yeah, I remember he had a bunch of info on his website. I had actually found Brian on ebay, back in the early days of it. He burned a custom chip for my TPI engine. He also updated it for me a few times to get some bugs worked out. He seems to be a real nice guy, but I think all my correspondence with him was via email as well.

 

[JamesSam]

I am away from my truck right now unfortunately, but from the research I have done last night and this morning, if this is from an adjustment to the TV cable, shifting hard in to 2nd gear is not bad for the transmission necessarily.

Was it stuff you bake for high heat? VHT has you do that at 200° for an hour.

Last night I finished chopping up a rollbar meant for a long bed to fit into my short bed. Just gotta finish welding and cleaning now.

Last week I finally put in the new cluster relay board and switched all the bulbs to LED. Everything works on my dash now!

No, it’s an isocyanate activator mixed 8:1 which hardens the oil based enamel paint.
