Yes, it seems to be resolved for now and running well. Other issues are still revelent, but the simple fix did the trick. Thanks for your assistance.

I had a problem with mine the other day. After I got some gas in, it wouldn't start, until I let it sit for a couple minutes ( while checking the connections.) It started up and is fine so far, but I'm going to look over the sensor connections again.

BTW- I put on all new connectors over the winter, except for the TPS one, but I'll get to that soon.

Use a Volvo TPS connector if you can find one. They're quick release like the Volvo and BMW injector/sensor connectors.

I got a whole fuel injection harness from a BMW, and it had several connectors on it to fit the TPS. All the connectors were the quick-release type. The color of the connectors even matched the corresponding injector or the sensor

Only one? I've picked up several BMW and Volvo fuel injection harnesses over the years. Thought about swapping the entire BMW or Volvo harness on to the Z or 810 but it's easier to just do the individual connectors. The color match thing doesn't mean anything to me. I've done both of my cars, sold a few sets of connectors and kept a few for backup. I actually prefer the Volvo connectors over the BMW connectors.

One complete BMW fuel injection harness was enough for me. It had enough connectors to do several Z engines. Inly 25 bux from vinesauto (www.vinesauto.com)

Just an update on my running rough-

I replaced the cracked rubber diaphram from the vapor can, the local Nissan Dealer had it for $5. My car runs a whole lot better now, but still periodically not as smooth as it should be. I think I may have a fuel pump starting to fail. I've noticed that my vehicle has a real tough time running smoothly when the tank is less than 1/3 full. I'm going to check this theory a little more, but I'm pretty sure my 31 year old fuel pump is on its way out. I have not done a fuel pressure test yet, but I'm going to try that next.

Water temp sensor tested ok. I cleaned the connections there, and found my thermostat housing is leaking a bit between the housing and the engine. I have the new gasket, but it looks like its going to be a total b***h pulling it off, cleaning it up, and replacing it.

Be very careful removing that housing. Those bolts break easily. Especially the ones that go into the head.
