OK who was it, who drives a 94ish grey Z28 with a SS hood and an aftermarket spoiler?? Come on you know who you are, you backed in right next to my purple 92 camaro and didn't even have the deciency to come find me. huh!

John

That would be Jason aka Daddy. JC you pimpin the 94 yet?

Silas, you snitch!

Yes, I got ya. Just didn't know who you are. I was there visiting a friend. And didn't want to ask a bunch of people who's car this is. My bad

There is also a red LS1 Z28/A4 up there. You know who owns that one. I ran out of flyers so I couldn't tag him as well.

Of course I know who that is your in my territory now pal!! J/k yea hes one of my best friends and unfornutately he leaves in june (well good for him)

Yea John the 94 is up and running but not pimping it yet. I am having idling issues in closed loop. it keeps on stalling, It runs fine until it gets out of open loop and then as soon as I come to a stop it stalls. Do you have any experience with that if so I could use your help. I'll tell you what I'll get up with you soon.

John

JC what cam are you running? Hotcam or 306? If it's the 306 YOU WILL need a custom program w/ it no bones about it. As far as your problems if it's the hotcam check all the vacuum lines, your 02's may need swapping out if they're old (unlikely them but still very possible). You are running pig rich and if anything clean the IAC and also check your MAP sensor as well. You shouldn't have to drill the IAC for the hotcam but if no custom program and a 306 you just might.

You also may want to readjust your rockers they may be too tight from what it sounds like. Worse case scenario is your timing is off from the cam install that would blow chunks.
You got Hooker LT's on there too don't you?

I got the 306 in it, I don't think the timing is off cuz it runs great above idle. I got a custom program from pcmforless.com. I don't think the rockers are too tight, I adjusted them twice so far and was very carefull when doing it. Just about everything is brand new on it to include the O2's. The only things stock are the injectors (I know i am working on new ones) the TB and the MAF. And yes I do got LT's

I am going to run a datamaster on it probably sunday to see what the computer is doing and take it from there.

Give me your number and I'll give you a call if you want, ohh and I don't live way out in the boonies anymore. I live in Steinwenden now. 1 town over from ramstein village.

John

Have you looked at the TPS? May need slotting if anything. Something definetly sounds fishy though if it'll run initally then cut off. I personally never had the problem but several of my friends did w/ various symtops. Could very well be the timing not being lined up.

I'm tdy right now in Turkey and should be back the 1st or 2nd wk of May if not sooner but I doubt it.

Steinwenden? You not far from where I live. About 6mns. I'm in Oberstaufenbach village.

dont want to butt in too much

The TPS should run on a minimal setting, meaning that the computer will average it out. As long as you dont bust the max voltage at WOT, the computer will just reset the low values as closed throttle so it can actuate the idle speed motor. I had a problem with mine (damn that BBK T body)

If you guys come up with a cool way of setting the rockers let me know. If I dont set them with the engine running I cant even get close. WILL SOMEONE DEFINE 0 LASH!!!!

We kinda got a up on the 93 in that our Map sensor is on the 4th or 5th thing the 'puter will check, but it is important nonetheless and worth checking.

I got basically a 306 as far as lift, but my lsa and duration are differant and I suffer from the "so you want to lift throttle and idle, then I'm gonna die syndrome" as well. You pretty much diagnosed yours, if it runs good in open loop thats standard data, if it wants to die out in closed loop, the left hand is telling the right hand differant stuff (basically its a tuning issue traced back to the program.)

If you come up with a magic bullet for the idle let me know. Its still kinda funny when I come to a stop light and it dies, you see the guy in the next lane kinda giggle, then you fire it back up, his jaw hits the floorboard, and he lets you go on your way *laugh*

Just maybe the idle needs to be set higher. I know those BBk's are junk I don't care what no one says. They tend to stick when cold and then change altogether when warm. Him having the stk TB he should be good.

Rob what you mean you can't adjust w/ the car running? Why not? That's the only way I'll do it because I suck doing it w/ the #1 tdc method.
What a little hot oil got ya scurred?

no, thats what i mean. The only way i can do it is with it running.

That crap about #1 TDC then do the intake of this one, the exhaust of that one stuff never works for my car

Oh ok. I know what ya mean. Ryan he's got that crap down pat w/ #1 tdc. All I know is when he goes to 0 lash he just basically does a 1/4 turn and then twirls the pushrod. If you can barely turn it that's where he stops. How accurate it is I don't know but his car runs w/out a hiccup and the valvetrain is quieter than stk. Makes me sick sometimes cuz he's so damn good w/ that.

The way I do my valves is probably the way your talking about. I disconnect the coil and bump the ignition until I see the exhaust valve start to come open and tighten the intake and then I keep bumping the ignition until I see the intake start to close from wide open and then tighten the intake.

As far as tightening the rockers I tighten them until all the wiggle (sideways and up,down motion) is out of them and then go another 3/8 turn and lock them down. I don't use the twist the push rod till it stops turning method cuz you do that and give it another 1/2 turn and they are for sure too tight. just my opinion.

With my problem I think it's a tuning issue, everything I read points in that direction. Tomorrow I am going to datamaster my car and see what all the sensors are reading.

I'll let you know how it turns out.

John

Ihad the same issue when my car was cold . Iended up drilling the the bleed hole in the throttle plate slightly larger .
