Chasing down an air leak........ could it be?

[khislop007]

Maybe the long drive to and from the fest may have smutted it up again

Just rid your problems and give me the maggie

I wonder if that pulley is binding just enough to make it bog down???

Maybe???? I'm just shooting in the dark..

good idea!!!! take the blower off install the stock intake manifold and see if its still doing the same thing.....i know thats asking alot but at least you can rule things out

So the shop saw issues in the fuel trims to make them think there's a VAC leak, but smoke test doesn't show any such leak.

TOOOOON perhaps?

Test the coil packs. Make sure they're good to go as well as the plug wires. I have always felt this is an ignition related issue. There should be a resistance value for the coil packs that someone can post up for you. You can test them with a multimeter. Same with the wires.

Yup. The other one was right there at the end of the hose. I just cliped it off and reattached. No difference.

I'll hold on to it for now.

It looks pretty clean. I geuss I could take it off. Wouldn't take maybe 30 minutes.

Well. You and I have already seen such weirdness. A few times. hahaha

I just sent the stock manifold to Shardik2SS (Nick).

I have a meter. I'll check. But walk me through it.

Is this meter right?

y are you measuring volts and not resistance?

[Speedy1975]

Yeah, that's the meter, but you wanna find the value range the coil pack should be in and measure the resistance.

Anthony had some data earlier, maybe he can look up the coil pack test procedure for ya and post it up.

If you want to test you coils this is the fast way to do it but plz be careful. Remove your spark plug and attach it to the coil you want tested.
Holding the plug wire with insulated pliers, find a spot on the engine that is a good and easily accessible grounding point. Pretty much any exposed metal, including the engine itself, will do. Holding the spark plug wire with your pliers, touch the threaded portion of the spark plug to the grounding point. Have somebody crank the engine with the key, and look for a bright blue spark to jump across the spark plug gap. If you see a nice, bright spark (clearly visible in daylight) your coil is doing its job. Good luck

[anthonyj9h]

Also in your service manual should be the resistance rating of the coils

[anthonyj9h]

im not going to do everything for you! lol

Hmmmmm.......

I remember doing this a long time ago to find a cylinder that was misfiring badly. This one is baaaarely misfiring, it at all. I don't think my eyeball would be able to tell the difference?

How bout I go buy a temperature gun and measure the cylinder temps? I think they are only like 30 dollars.
