TOP END REFINISHING

[5ABI VT]

Schrade Awesome thread especially with all the pics. I wish I could contribute but I haven't pulled my plenum off yet. I plan to and Ill be eliminating the coolant in the plenum and tb as well as the secondaries when I do mine. Your pics and all the little steps you've gone through are a huge help =D>

Thank you Sir! The thread hits were plenty encouraging, so you helped I'm sure. And
if I can get it done, anyone can (of course, it ain't done yet [NEVER is], but nothing got broken, and no 'problems')...

I could not get the 90' plenum fitting tight in the correct position, for the TB / coolant by-pass. The fabbed by-pass line is still in place, not obstructing anything (see in the video), so I won't have to yank the top to re-reroute it at a later date.

I tried Teflon tape on the fitting threads, and then thread sealant, without the tape, but didn't feel comfy with that. So for now, it's still running through the TB.

First post edited for Cliff's links info...
DEFINITELY read Cliff's links when he posts them. They're not always directly to the pertinent information - you'll have to read it ALL to get to the info, but it's ALL there, and you HAVE to go through it. (Thanks a ton for that stuff Cliff). Use your bookmarks tool in your browser for it, and note that sometimes you'll run across info that's IMPORTANT at a later point...

Is it running yet? If so how well?

Sounds good have you had it on the street yet? Curious how the auto will do in the car?

What's it idling at?

Still idling at 1k, with TPS calibrated.

And, it's not steady - about a 75 RPM swing, so I can't tell if it's a vacuum leak lope, or what...

To boot, I don't know about the hesitation gig.

New DataMaster uploading now; called Jon B / FIC, for new injectors, which I think are indicated by the DM vid...

Have you set the Min Air adjustment? When you get DM connected, what is IAC doing at "idle"? How many IAC counts? What does "TPS calibrated"mean? What is the coolant temp as it's idling? Why do you think you need new injectors?

[mike100]

All you need to do is make sure your TPS is set to the indicated voltage at zero percent opening (about .54v if i recall). The IAC counts are probably 0 if it can't make it run slower than 1k rpm.

you either had a line pop off during reinstallation (or a mistake in tube routing), or your throttle body blade redo got messed up a little. Just seems like too much air. maybe you should double check the throttle angle and not the electrics.

Minimum air adjustment? You mean the throttle stop screw? Haven't played with that just yet...

TPS calibration - set TPS at .54V with adjustment screws.
