I got my car back form my tranny shop a little over a week ago. I was having the transmission rebuilt and a clutch and flywheel put in. When I picked the car up, they told me to check the electrical connections on the nitrous system to make sure everything was re-assembled correctly and securely. I gave it a once-over and didn't notice anything wrong. It opened, closed, heated, purged, and sprayed at the WOT switch (checked the WOT with the engine off). So once I had a touch over 500 miles on the odometer, I decided to give it a test run. I went in 3rd gear and rolled into it once I was past 3.5K. When I hit it, the thing surged forward very hard, then slowed about a 1/2 second later, and then started bucking a little bit. I figured that the new clutch was just slipping a little and I needed to wait another 200 miles before hitting it again. I hit my 200+ mile mark today so I tried it again tonight and the same thing happened. Afterward, I checked my bottle and it was only about 70% open. I figured that theoretically, that could cause problems. I then opened it up all the way and went back out to try again. Same thing again, complete with a monstrous initial surge. But then the bucking got worse and the engine stopped and my dashboard lit up. I put it in neutral and coasted into a closed gas station. Right there I'm thinking how I was going to have to get a rental to make out to my accounts tomorrow, seeing as I was sure I just had a major internal-engine FUBAR. So I just sat there shocked, angry, and depressed. So I figured, what the hell, I'll try and start it. To my surprise, it cranked over a couple of times then started. Everything even seemed normal. So I drove it home real easy and didn't have any problems. Now I had to start troubleshooting this thing. First thing I was going to look at was the nozzle/jet area. I was going to remove the nozzle and spray it into the atmosphere just to see if it was working right. While taking the fuel and nitrous lines off, I noticed that the shop didn't put any of the jets back in!!! I was probably spraying a 300-shot or something utterly ridiculous. I'm thinking that the only reason my engine didn't have a serious failure is that all the fuel made the A/F ratio so rich that it kinda cancelled out the nitrous. I only babied it home about a mile, so I guess there could be problems I'm unaware of, but everything seemed to be fine. I'll post back if anything develops.

 

Wow, thats some crazy ****. Thats why I never let shops touch anything from my nitrous setup when I have to take my vehical in for repairs. I hope you didn't hurt the engine too bad, but I am 90% sure you have a major FUBAR on your hands and the engine might need to be replaced.

 

Yeah, I definitely wasn't too crazy about them messing with it, but I had no choice

I guess we'll find out about the FUBAR pretty soon. I have to leave to drive 300 miles to and from one of my accounts at 10:00.

 

wow, thats nuts. sorry about your troubles. but if the shop only worked on your tranny, why would they be messing with the nitrous\fuel jets inside the nozzel? Good luck, hope nothin broke.

 

Must of been one heck of a shot!!!

My guess is that you may be ok, remember that the nitrous jet is approx twice the size of the fuel jet so if both jets are missing you should be putting in almost twice the amount of fuel for the amount of nitrous you are injecting. Of course that theory only works if the pressure stayed up. Your nitrous would drop fairly quickly but the fuel pressure probably dropped immediately with no fuel jet.

Do a compression check you will soon know.

 

Hind: They had to remoze the intake for the job and that's where the shark nozzle is. Since the nitrous and fuel lines don't have much slack in them, they had to be removed to remove the intake.

Jime: Yes, it was scary fast for about a 1/2 of a second. Traction was a problem in 3rd gear!

I wish I had time to do a compression check before this trip.

 

I made it there and home without incident. It was fine so I started beating on it a little and it held up. So, towards the end of the trip I decided to spray (50-shot) and it felt and held fine. God bless the VQ.

 

what clutch and flywheel company did you purchace?

 

SPEC flywheel and SPEC stage 2 clutch.

 

Happy to hear another VQ story. What prompted you to rebuild your tranny?
I think the 99's can fix themeselves sometimes..

 

Center diff bearing went bad. 2nd gear was pretty worn too.

However, why in the hell would they touch/remove the jets from the nossle?

Forgive my ignorance, but that doesn't make sense.

 

They needed to remove the intake tract, and the lines are plumbed into it. If they completely unbolted the intake tract, the nitrous line only has about 6" of slack, and would somewhat hold the tract in place. And when you undo the lines, the jets just sit there in the end of the lines, with nothing to hold them in.
