What was the problem? I'm trying to get my own -16 to run smoother. Trying to rig up gauges to confirm pressure regulator pressure.

It was the most bizzare problem. If I started it and never turned it off it didn’t surge at idle. If I turned engine off and restarted it while hot, it surged and stalled. So a hot start problem. Get yourself the electrical flow chart and run through it. It’s the only way you will know for sure and how I found my problem

@@robgimenez5031 Thanks for sharing. What was the final fix? A temperature sensor or new ecm?

@@ebutuoyebutouy what I found was a partially broken wire leading to the EHA unit. I thought I was so dumb that I couldn’t read an multi meter (reading zero) when I bumped it and saw it spike up in ma The wire was super brittle and when I stripped it back, most of the copper wire strands were broken with only a single strand unbroken. So I had a donor car and used the plug which gave me a bit of extra lead to enable a fix. Soldered and shrink wrapped. Solid fix. It was amazing to finally see the cause of the problem. I swear I turned the car on and off 20 times before I was convinced that I’d fixed the problem.

@@robgimenez5031 Gotcha! Nice find. Thanks for sharing. Enjoy your -16.

close enough if this is the key on engine off test
