New Owner with Q's

[scottfab]

Yes indeed welcome to the party. Lots to learn.

One way to learn bunches is to use the "search" feature of the forum.
Go to the Technical section for instance and search for "clear codes".
Read up. You might also try "read codes". There is a cumbersome but effective way to do it with just a shorting strap(wire). Or you can buy that appropriate scanner to do it for you.

How does she run with the power key off? No need to trouble shoot the secondary system if you've got issues when they are not engaged.
If all runs fine with the power key off then assume, as has been mentioned, fuel pump and/or injectors and/or vacuum leak issues.
The leak you've described does sound like the check valve.
If you're going to pull the plenum consider cutting some gaskets yourself out of rubber. They can be used over and over without coming apart. Regular inner tube rubber works but you can find large sheets of the stuff on line. When the plenum is off you can use it as a guide for cutting the new gaskets.

One thing at a time. I'd suggest a separate thread per issue. It's not only easier to focus on the task at hand but can also be reused/found in searches by future forum users.

Plug the end of the hose and if the secondary pump stops, the culprit is more than likely a little check valve on the secondary hose under there. I believe they are still available at the dealers. Part number 460734.

Another item to replace if you go under the plenum is the secondary vacuum tank, it is probably the biggest cause of the check valve not working correctly. That’s available from NAPA, Part #21013, it's only about $10.

Get some gaskets from Jerry and the parts above and I'll bet your problems are over.

I was actually wrong about the pump running all the tie when you pull the hose. It will be the same as when the car is normally running or not running. Just turn the key on, don't have to start it. If the pump is cycling as you mentioned, plug the hose, if it stops, then the check valve IS the culprit.

I would change the coolant also, especially if it sat a lot.

Agreed. Burnt oil smell after WOT runs sounds like crankcase pressurization. Check for oil leaks but the cause will be venting of crankcase or actually not venting crankcase.
So PCV first, if not, then cam cover vents.

Ok, thanks for all the replys and suggestions. Hammer, I'll try the tip you mentioned tomorrow.

Regarding the smell, I have to admit what was determined.... a little embarassing.... it would help if I didn't slip the cluth at high rpms. That problem is solved!

Took it to the track, today. Wow, what a blast to drive! This car is awesome and can really pull. It really is a beast. At some point, I'll write up a comparison of how this car drives compared to my '04 Z06. They really are very different. Handling goes to the Z06, fun award goes to the ZR-1, and since I'm not trying to win an award on the track; I like the ZR-1!
Its funny, I had a decent amount of comments on it being a ZR-1 and a few people seems agast that I was willing to risk tearing up the ZR-1 on a track versus keeping it in my garage clean & safe. Other than the wheel bearings, this car seems to be very well put together and feels really solid on the track.

The motor is bulletproof. You can't kill it accidentally. So u can drive the p*ss out of it. More so than an LSx. Something else will give out before the motor.
