in some need of help

suprakid91 · 04-18-2008, 10:46 PM

my car has been running just fine for a while now and all of the sudden all sorts of stuff goes wrong. just adding more check marks in the bank... ha. but anyways i need some help, whenever i am driving normal or getting on the gas whenever i push in the clutch to the floor and let the RPM's drop it just dies. hard. like no rough idle then die it just goes down. i have no idea what it is. i have pretty new vacuum lines and all of them are connected. i was thinking of just turning up the idle so it stays at like 1000 rpm but i have no idea where the idler screw is at. if anyone knows please share

haha so i dont know what the problem could be. any help from you guys would be great.

gte. i was just wondering if it had one. but i guess not. i was just trying to get it to rev a little higher, so how would i go about doing this?

there is an idle screw but i wouldn't screw with it yet .
i'd check all vacuum lines and read the engine codes

you must throw a code when it dies like that

check vsv values hidden under intake they are about 50 bucks

if faulty they wreck fuel mixture , bad fuel mixture = bad idle

N/A's have idle screws????
I'm all ears.

I have been told enough that they didn't that i just worked around it and never really payed it any mind.

Actually, both GE and GTE have "idle screws" they're NOT considered a serviceable item at all. There's a reason they're not even covered in the TSRM.

As a side note, I've seen people adjust the WAY wrong things before when trying to adjust the idle... and effectively doing so but at the risk of causing damage: dash pots, air regulation screws and my favorite..... over tightening the throttle linkages so the throttle plate is always partly open and the IDL switch is never closed.

Gee..., let me run this buy you sinse I seem to have you here.

Upon start after heat cycle and it idles down. It had a miss. Now it seems the miss has gone after a bit of driving. I'm throwing the 31 or 32 afm code. But my shites new and I think I'm throwing it from a filter that is not dry flow and the old sup had blow by.

I thought this may have been the cause but now I wonder that after driving if things aren't just seeting up propperly.

Thoughts or comments? Sorry to thread jack. Not my intention.

Whoa, try that again... and slower. Sorry, but it reads like a Chinese translation of a Russian stereo that's been translated into a French equivalent of English.

I think I get the jist... same problem that we've spoken about a number of times previously? Well, same answer. Test the harness. Particularly the VS signal wire and VC sensor feed wire.
