When car is cold it bogs on 20% throttle

[thepowderblue]

But only sometimes. When I am going to take off it will just not have any power and it will have a little bit of a miss sound but when I give it alot of gas my car taked off like everything is fine. It only does it sometimes when my car is cold.
When it worms up it is perfectly normal.
Kai just helped me set the dizzy timing a few days ago so its perfect
I was thinking it could be my dizzy, plugs or wires.
I have never changed my plugs wires or dizzy. but the wires are aftermarket
when I got the car it had a cam position sensor problem so I swapped the cam position sensors form another dizzy that fixed that.
The plugs where good when I got the car and I have put like 30k on but I doubt plugs would do that.
Any other ideas?

If you have already cleaned the fitv and iacv, I would look at your wires and see if they need replaced. I had similar issues, it ended up being a crack in the coil wire.

The car idles fine. Ill change my wires.
Whats fitv. Do you mean the fast idle valve? If so I think its good. I might make a block off plate for it.

Yeah the fast idle valve. No need to block it off, just clean it. But its strange it only does it when cold...

And only sometimes when its cold. Have you ever gotten your air filter wet and it makes your car run funny, Its almost like that.

I would say fuel filter and plug wires. When my car was doing it, it didn't run right until after about 3k, severe bogging before that.

[thepowderblue]

Really, Fuel filter? That does not explain only ~sometimes~ when its cold

I was thinking like a bad plug but thats a big maybe or a bad wire or a weak coil or something like that in the dizzy.

It is actually called the fast idle thermal valve....without the thermal part it may sound funny to be related to temperature. To the contrary, the FITV operates solely based on the engines coolant temperature. The colder the coolant/engine the more air the FITV should allow to by-pass the throttle plate. If it is out of adjustment it could cause some bogging issues.

Another issue could be a the EGR valve being stuck open or opening too early. (if your car is so equipped)

I understand. Should I just get or make a block off plate

Yeah, uh, don't know why I said that. Just look at the wires for now, if you don't mind a small shock you can run your hands over the wires and check for voltage leaks. You'll only get shocked if there are cracks in the wires. Also are your wires plugged all the way in, by that I mean are they flush with the valve cover?

Yup. I only got like 3 hrs of sleep last night but Ill swap them. I will have to weight to test drive it because its hot.

Let us know how it goes.

What is the condition of your spark plugs? Are your tube seals in good shape, or are you leaking oil onto your plugs?

I'm thinking that maybe you have oil on your plugs that causes bogging and misfiring at startup... and once it burns off, the car runs normally.

It is actually called the fast idle thermal valve....

Fast Idle Thermo Valve, actually.

[thepowderblue]

I dont have oil in the spark plugs.
I put new wires on and I think that fixed it.
The car seems to run better. It use to shake like I had bad mounts at idle but it does not do it anymore with my new wires
I also rerouted them
