914World.com _ 914World Garage _ A really bad experience in traffic Friday PM

Posted by: DNHunt May 28 2005, 08:11 AM

I broke down on highway 16 (freeway to the Narrows Bridge) yesterday. Traffic was a a crawl so I got out and pushed it to the shoulder. Awful embarrassing, but no harm to the car. After some messing around I found I had spark and way too much fuel. It turns out the manifold air pressure sensor went out and the ECU thought the engine was at wide open throttle so, it flooded and died. I'm not sure if the diaphram broke or some dirt got in it or if the electronics busted.

Luckily, I had my laptop with me so I reprogrammed the fuel map to lean out the lower RPMs. In the time it took to do that the plugs must have dried out cause it started right up and I made it home (still awfully rich). Thank you programmable FI. A first for me, I ran speed fuel injection instead of speed density fuel injection.

After I got home I found out I broke a solder joint in a connector. Repaired and ready to roll.

You scared me with your title. I thought it went off a cliff!

But glad you made it home safe and glad you had an interesting learning experience today.

Glad to see ya again. It's been awhile since I seen you post last.

Somewhat similar happened to me yesterday !

Took the car out during lunch time for an errand. On the way back, i was progressively losing power. At the end, it would'nt even idle. The real problem is that it finally died in the middle of a fairly busy downtown street . . . right in front of the office !
There's a university a block away, and two college kids I asked helped me push the car around the corner and I was then able to coast down a slight hill to the building's indoor garage.

I had filled the tank in the morning on the way to work.

Got CAA to flatbed it home after work.

This morning, I crawled under the car and sure enough I found a rubber fuel line that was twisted and obviously would'nt let gas through. I re-routed it, and it now runs fine. And I now remember that when I originally connected the fuel line, when I swapped engines, that I had fussed with it and was'nt completely sure it was going to be ok.

The joys of modifying and fixing old cars !

Thank God you weren't ON the bridge, or everyone behind you would have picked it up and thrown it off the side!

Glad it's running again Dave. Sounds like you need a copilot to work the laptop for you while you drive.

love to hear self repair stories. sorry about the break-down but think it's an incredible credit to the owner/driver/mechanic for understanding the whole car. i also learn a little and hope to remember things when it happens to me. do you think the ricer crowd can do this?

Got red flagged on my first run...AUGGH.

Had to go begging duct tape....AUGGH 3.

& worst of all, I was slow

but you (the car) looked good jp. speed is relative. i didn't get a chance to ask how you handled the trim delete on the rear of the targa bar. sure looked clean. it was a tough course. even the locals were getting lost in the sea of cones down at the far end. 96(?) cars, what time did you get out of there, 6pm?

Yep, that was Gerry driving. He got about 6 hours of seat time this weekend. We were on our way to Eugene for family stuff. He did most of the driving. Fortunately, I have a new clutch and 1st gear waiting.

Chris the 2270 didn't make it through break in. The rings never seated and the cam went flat. Parts are coming back to me this week for round 2. Jake and Charles have been really good to me and everything has been repaired or replaced. Neither of them had to do that as the original contract said it would be on me.
