Very cool!! Congratulations!

Thanks, a pretty big day. It was quite a rattle trap with no rubber anywhere. Seemed to shift ok. Power steering wasn't working, not sure what's up there. Engine feels like it's missing, I'm going to have to do some diagnosing, ran some codes but want to run again since I ran it out of gas that might have influenced the lean bank 1 and maf codes.
Almost ran through the neighbors fence because my throttle is too close to the brake, I'm changing that today!

Even with the minor hiccups I'd wager that was a tremendous buzz to get it out on the road and running.
After all this time of thought and labour you've thoroughly deserved getting it out on the road and having the thrill of it actually running.
To use a Kiwi praise phrase: 'She's beauty like a tip-truck!'

And you'll get it even better...

Always a milestone when you go for that first ride! Well Done, good for you! It was good to see the smile on your face. 8-) Congrats

Thanks! I did a re-shape of the throttle pedal arm yesterday so that should be better. I'm going to run it for a while today and try to do some more diagnostic work on the engine, see if it really has trouble codes. it's always felt to me like it has a cylinder not firing, unless LS motors just sound a little choppier I don't know. I don't get any misfire codes though.

Cleared my codes and ran it up to temp and checked for codes again. Just a P0171 lean bank one. Checked the vacuum hoses and sprayed some starting fluid around the intake and various fittings-no change. Seems likely it's a vacuum leak but I'm not finding it. I suppose it could be an injector plugged up but I would think that would give me a misfire code. I checked my fuel pressure a while ago, it's a new pump too, and new fuel filter. Kind of stumped right now.

Do you have a shop around you that can clean and test injectors? There was a place near us that would let you watch each injector run in a clear tube and then they would run a cleaner solution through them and you could see the results for yourself

I don't know about a place to clean them. I did externally clean them when the engine was apart. I ordered a basic smoke tester today, so I will check the intake and exhaust for leaks, should be a handy tool.

I was thinking about your injectors and in a search I found this. I agree with the host that having this done professionally is a better choice - but still.. the "bad"side of me thinks this looks like fun! HAHAHA.. Anyway- have a look - I couldn't help myself.. And this is cheap entertainment!

I think you left out a link.

Awesome, congrats. I thought the site had died it's been down so long. It was a pleasant surprise to find it and your Stude up and running.

I got my smoke machine today. I wish I had always had one of these, it is so cool. Didn't find any vacuum leaks but did find a couple exhaust leaks, one right above the O2 sensor, so that is probably my lean bank one code. I put ultra high heat silicone on the joints and will recheck with smoke again tomorrow. These new fangled cars with O2 sensors don't tolerate exhaust leaks like the ole carb did.

Well I fixed the exhaust leaks but the lean code remains. Really thought I had found the problem. Next plan is to switch injectors from left to right and see if the code bank follows.

Took the injectors off yesterday and found one on the lean bank with a chunk of debris in it. They all looked dirty so I ordered a remanufactured set. Hoping this will do it, fingers crossed.
