Sonoma gt input

Alright I'm gonna try and sum up this whole gig as much as possible. I picked up another GT a couple weeks ago that had been mostly sitting for the last 2 years other than the occasional monthly around the block make sure it runs deal. I get the truck home start in with plugs runs a little better do wires cap and rotor big help there, so move on to fuel filter it was packed full of crud of course so now were running pretty darn good suprisingly! Next trans fluid and filter now a make a few runs out here in the boonies and shes really suprised me shifts good and firm in all gears WOT shifts are about 5200 5300. So it sits for a day or two then drive to work feels like a big turd kinda bogging WOT shifts are now down to about 4700. So replaced both knock sensors same deal poor running! Searched the vac lines yesterday found 2 cracked so replaced those unchanged. So now today gonna recheck all vac lines to verify their all good and check the timing. So what I was hoping for was a little advice from the pros here on where to go next with the goofy thing maybe something simple I'm not sure. Couple things I didn't put in above fuel tank was sucked dry early on like right after I got it home gauge was a tad off imagine that! So it does have fresh gas ran half can seafoam through booster half in tank, also some heet incase their was water. Sorry for the 9 mile post and TIA for any input on this.

Yep, check fuel pressure. Could also be the spyder injector setup. If it is spyder, Al @ Wynjammer is claiming to have a better replacement. :2cents:

Well Jeepruby and I set the timing today was off a little ways big difference! So now on to the above mentioned what is base fuel preasure and how is it set? Still shifting a little early other than that its running really well. This may be something else what is the stock shift rpm's for the 1-2, 2-3, 3-4 shifts at WOT on the Gt's? Thanks for the input guys!

Well put a gauge on it tonight key on engine off 59psi is what I got. So shut off key and let it set for awhile settled at around 50psi and stayed there. So started the truck with the gauge on just to see what it did. Basically stays on 55 or so just fluctuates a little with throttle input. So i would say that looked pretty good. Just don't understand the shifting is that normal? Can't find the rpm's for shift points at WOT. Anybody got any other ideas? Thanks again! :D

Re: Sonoma gt input

That was our thought the other day so adjusted it like normal and didn't get any change. I'm gonna reset it again tonight then try the clamp and see what I get. Thanks Dave.
