Just completed a DEK swap in my 96. The car takes about 4 to 5 cranks to start up, then I have to keep my foot on the gas for about a minute to prevent a stall. It also stalls out after releasing the gas while driving. I'm using my 4th gen IACV with a 5th gen throttle body and block off plate. the hose between the block plate and iacv adaptor is about 4 inches. I'm also using a 5th gen TPS since my 4th gen tps broke. I'm using an Injen intake for the 96 and the hose that goes to the valve cover is a bit loose (need a clamp).

I'm having a weird issue with my innovate wideband...its been installed and working well for over a year, but after the swap it stays on full lean and barely moves at all. Does it have to be recalibrated?

I have an idea about the starting issue being that I need more and better grounds. How can I fix the idle issue? Also, whats the best way to check the manifold itself for vacuum leaks?

BTW, I don't have evap or egr in my setup and any vacuum nipple that wasn't used was capped off.
Would it be odd if the idling issue wasn't vacuum related, but instead related to bad grounds and bad CPS (flywheel side)?

if the car will idle you can use carb/choke cleaner to find vacuum leaks. Spray it where you think it may be leaking and if any of it is sucked in the rpms will increase. Make sure you don't have vacuum leaks first and then try to figure out what else is going on. The starting problem sounds like typical IACV stuff but if you have vacuum leaks it's hard to tell.

I checked for vacuum leaks using starter fluid (i know its dangerous, but thats all I had). No vacuum leaks, just gotta check the factory egr block off tomorrow.
I also added 3 or 4, 8-awg and 6-awg grounds to the front head, throttle body, and the two grounds near the front of the intake manifold.
I eventually got the idle pretty good by adjusting the set screw (even though I bought the 5th gen block off and 4th gen iacv adaptor).

I discovered yet another issue. I loaded up a DEK basemap with 2-step launch on my emanage ultimate and the 2-step doesnt activate, even though it used to work before the swap. I know the 5th gen tps works because I recalibrated in the EMU software and the volts are 0.52v = 0% throttle and 4.13v = 100% throttle.

Once I get the car started, it seems to run fine (just needs a good EMU tune), but I'm pulling my hair out with the starting issue. It still randomly needs a couple of cranks to get going.

Most likely you do have vac leaks, take the IM off and reseal everything and use some new hoses, because most likely that Wideband isnt lying and stalling sounds like a vac leak issue.

Stalling issue has pretty much gone away, but I'll recheck the vacuum this weekend. The only issue I have now is a hard start. I even tried to prevent this by wire brushing the mating surface of the tranny to block prior to going in the car.
I recalibrated my wideband this morning, but I think the O2 gauge is still out of wack for now because of a minor exhaust leak.

I may have found my lean condition...
I unplugged all three rear coil packs at the same time and it made no difference whatsoever to the idle...here's the thing though, one of the rear coil packs is brand new...

btw, I have a CKPS (Ref) code (due to a used UDP with a bent timing ring). Could that cause the coils to not fire? I'm going to put in my stock pulley this weekend.

so whats going on with this did you find the problem

ya the DEK is now running like it came from the factory. No starting issues, no idling issues, everything is perfect. I accidentally left the rear subharness unplugged. I never thought the engine could run on 3 cylinders, but I drove like 5 miles like that.

Its just part of working out the bugs after a swap.
