Belt Snapped Update + New Issue Missing?
Well, after a 2 hr wrestling match I got the belt on.
I would say now I have a new problem, but it's not really new.
Noticed it just after I got the car home.
Car doesnt seam to "coast" well. By that I mean, roll at about 35-45 mph, and it kinda jerks. forward and backward.
I decided to take some time and rev the engin in neutral.
Car runs smooth up to about 1500 rpm. Then it fells like its missing on a cylinder or something. Just doesnt rev smooth.
Any ideas?
Looks like I'm headed back to FLP.

The rough running was evident before the belt snapped.
So although I will look, I'm thinking a bad wire or plug. What does it run like when you blow the #7 cylinder? With my luck, I already did it....

When I put my blower on I used the ngk plugs. Well for some reason it ran good first 2 hours. After killing the car and it cooled I cranked it again and it was missing like you say I thought it was running out of gas.
Turns out 2 of the spark plug heads cracked and were arking ect. check that out

Looks like I'm headed back to FLP.THAT really SUCKS and I feel your pain BRO. Bring the car back to DAN at FLP and he will get you squared away and running reliably for sure, as he stands behind his work 1000% and takes great pride in his work (and is a an excellent forum tuner)!!

Torque converter lock up and was my first thought, so I didn’t worry about it.
But later I put the car in neutral, and reved the engine up to 1400 rpm. It no longer ran smooth.
In fact, this morning I dropped it off at Dans.
Pulled it out of the garage. reved the engine. Smooth as can be.
I figured "Why drop it off...it's running good".
Got 4 miles down the road, and felt the jerking. Put it in neutral at the light and reved the engine. Still feels like its missing on a cylinder or something. We'll see what he comes up with.
Thanks for the idea!

Possible Vac leak somewhere. Start up would have the choke on but once you warm up it may be leaning out.

Since you drove it without the belt on it might be something as basic as a fouled plug. The car would still be tuned for alot more incoming air, without the belt, hitting power enrichment at all would flood the motor out.
Vac leaks are possible, but being that the only vac lines are the booster, (you would know from hard pedal) interior vent in back of intake (to small to make a difference) and the two obvious ones at the T/B, it is unlikely. Dan will get you squared away.

Well Dan gave the car a good check over.
The coasting issue is a combination of what I called missing, and the torque converter lock up at low speeds. Dan changed the converter settings.
The missing issue is not being recorder on the cars computer as a miss. Or as anything for that matter. Everything seems to be running ok. It only shows up between 1400 and ~2200 rpm as kind of a skip in the smooth running sound and a short bounce on the tack. Over 200 it's smooth again.
Dan indicated maybe some better wires would eliminate the occasional bump in smoothness, but he’s not seeing anything really wrong.
He put a smaller belt on it, ~1/2” smaller, and I should be good to go.
Only time will tell, but so far Dan has been right on the money. The lack of smoothness was evident prior to the belt coming off, so maybe a plug is performing less than perfect, but not bad enough to show a problem. I’ll keep a close eye on it, and maybe over time the issue will be more discernable.
Thanks to Dan for the extra effort on making it run well.

I'm interested in this 1400-2200 skip/miss you are talking about. My MN6 has a slight 'skip' at 2000K when shifting under light load. This is recorded on my wideband as a lean spike/bump. I wonder if yours is doing the same thing...and more importantly why?

The skip/miss is kinda a smooth run with a burp every 3 seconds or so..
The tack drops a tick, and then goes right back to where it was.
It bugs me, but I’m not sure what if anything to do about it.
I was thinking maybe I would buys some new plugs and wires down the road and see if that fixes it.
What’s a wideband? Maybe I could get one and check…..

YOU should be good to go now and I knew DAN would get you up and running in no time!

You'd be suprised how small changes to AFR are tranmitted through the car. Typically this is felt as surging, hesitation, etc.
