It sounds and looks amazing! Great work! Have you figured out the idle situation yet?

It sounds and looks amazing! Great work! Have you figured out the idle situation yet?
Thanks! Yeah, I'm pretty sure it's either a dirty or bad MAF sensor. Everything else is testing good. I'm sure it'll run better once it's tuned, too. I'm still torn between sending the ECM off and having someone do it, or buying one of the J3 port tuners and giving it a go myself.
If you go the port tuner way, at least you have the option to change it if you like later.
That's what I'm thinking. I never tried using one but there seem to be plenty of resources to help figure it out.
I got my fenderwells finished and installed, lots and lots of 1/4 x 20 bolts in the front clip, and the forward wiring harness put back together. I used one of those GM weatherproof 6 pin molex plugs to connect it to the firewall harness; pretty cool stuff. I should have been using those a long time ago. I hope to knock out a big list of little stuff the coming week and then concentrate on driveshaft/exhaust after payday.
Lots more done this week; exhaust is on except for the tailpipes, clutch is hooked up and working, front bumper is on, hood hinges are on, pulled the MAF apart and cleaned it, figured out the tach wiring and got it working, plus several other small jobs. The front is sitting about 1 1/2" lower; the front shocks were too long and bottomed all the way out so I pulled them off and will get new ones. I started it this afternoon and let it run about 30 minutes. After stumbling for a few minutes it settled down; idles really nice and throttle reponse seems good. Vital signs all look good. Still need to get a programmer but this is pretty promising. For exhaust I just went with a couple of Summit's house brand of glass packs and 2 1/4" pipe. It has a really interesting tone especially when you rev it.
Bitchin'!!!!!
I love all these cars that we never would have thought about hot-rodding back in the day. Great project.
That is really looking good.
.
A lot of work BUT a lot of fun
Car is really looking good! When all is done and the tune up complete I think you'll be pleasantly surprised at the performance the little engine has---and the mileage!
Thanks, all. I'm really looking forward to test drive to see how it does. Still hoping for a May maiden voyage.
It's looking really good and you're getting really close. I know how ya feel for sure on the budget thing. My car is suffering really bad because of that right now. Haha
No pictures but I bit the bullet and ordered the programming module from TWEECER today. They are going to preprogram it so it should be plug and play if all goes well. Also finalized all the temporary wiring I had ran and wrapped all the wire bundles.
Sometimes the big bullet needs biting Good for you
Sounds like you're about set up then!
Pretty close; need to spring for a driveshaft next payday and that should get me on the road as long as everything works like it should.
Randy has a good thought.:) In my younger wrecking yard cruising days I often found just the right length drive shaft in the yards pile of them.;)
Jack.
It seems like when you're getting near the end of a project the small task list is endless. Spent the last few days putting on the front shocks, bleeding brakes, zip tying wire bundles & hoses away from hot items, finished the drivers side fenderwell, found wiring diagram for stereo amps & sub and got them mounted, put some tailpipes on, and several other things I probably forgot. My computer module should be here this week along with a few other parts. Man, I need a couple weeks garage break when this is over.
Keep up the great work!
It looks dang nice, keep at it! Nice score on the drive shaft too.
I finished up the tailpipes and man, this thing sounds bizzare. Doesn't even sound like a car engine, it sounds like a hopped up crotch rocket. Which, for a high compression Yamaha engine, I guess that's what it is!
:LOL: Very cool!
Well, good news, bad news. The good news is I got the chip in, chased down a bad TPS and the car started right up and ran beautifully......for about 20 minutes. All of a sudden it started smoking like a dog and blowing raw oil out the passenger side exhaust.:CRY::CRY: Its not missing so Im guessing a broken ring?? Whatever it was, it's got to come back out this weekend. And I was so close.......
At least all the fab work is done so it should just be pulling the motor, fixing it, and dropping it back in. Or getting another SHO motor if something is really broke bad. Ive got too much time invested in the setup and dont want to back up and do something else now.:mad:
Aaarrgghhh..:(:(
Oh so close... well, roll up the shirt sleeves and get after it right? I'll be crossing my fingers and keeping good thoughts that it's something simple! :)
Sorry to hear this Falcon, so close! Hang in there and don't let it stop you!
Ahhh Man.....that sucks.
Could it be something simple like it sucked an intake gasket?
.
That sucks.. Have been watching this build,,and,,yes,,a lot of headscratchin,,gone into it.. Hope it's nuthin too serious for you falcon.. You have done a nice job..
Hang in there Falcon, I bet it turns out to be something simple involving a minor tear down.;):)
Jack.
Sorry to hear this. That is definitely a bummer. I had some similar issues with a project this year and it is a bit of a set back. But, at least all the fab is done and it really looks great in there. I'm not familiar with these engines, but do any oil feed ports go through the block to the head using the head gasket to seal it? On 5.9 cummins it's that way and if the head gasket blows out near the oil feed passage you get oil blowing out the side. Could it be a bad valve seal or seals as well? Hopefully you'll get lucky and it'll be something simple! Good luck sir!
Fixed! The valve cover vent tube was supposed to be hooked to a fresh air tube on the throttle body but I had it hooked to manifold vacuum. It was sucking oil right out of the valve cover into the intake. Great news but I am going to have to pull the trans back out as the throwout bearing is not disengaging the clutch. But compared to what I though I was going to have to do, that's pretty minor.
That is good news! Well, most of it is!
Well that's a good deal!
Best news we could hear. Nice fix.:)
Jack.
At least you have peace of mind regarding the engine now! Sorry to hear about the transmission. I would agree with everyone else that this is good news indeed, vs. an engine tear down!
