View Full Version : OK, need technical help on this...

Spring has sprung here finally and it is time to bring her out of storage. Last year I had a surging condition later in the season (cool weather) that resulted in sticking WOT twice. Each time I was able to allow the throttle to release on its own after a couple of seconds but it is disconcerting and has to be addressed. I over oiled the K&N:nono :Buttslap :duh when I first bought it and as a result had to change my MAF relays. Is there a chance that some oil was sucked through and is now causing something to stick? Is it just build-up that can be cleaned out? Anyone ever have this happen?
Looking for advice...

No bites?

I'd start by cleaning the throttle body. Any oil from the K&N plus any soot may be clogging the Idle Air Circuit and jaming the shaft on the butterfly.

Thanks, Tuna, I think you may be right. From what I understand, these things should be periodically cleaned anyways, right?
Much to it? I should be starting on her next week...

Are you SURE that it is jamming wide open throttle? It is common for the throttle shafts and body to wear out causing a very high idle, but sticking WIDE OPEN?

If it is that bad, you can clean it, but you really need a throttle body. Mine is worn out, but it will only idle up to about 2,000 at most and blipping the throttle will return it to near idle.

If you buy a new throttle body, get one of the aftermarket ones with ball bearing throttle shafts. They should last forever.

Good luck,

Thanks, Doc. I did a search on the forum here and got over 10 pages of posts related to this problem including a few describing exactly what I'm talkin' 'bout:duh and I think it is the gunk built up in my butterfly pipes. This is causing the throttle to jam when I floor it past the usual travel point. I will be yanking it off to clean, I saw some pics here that shows how gummed they can get...

If you decide to clean it, COMPLETE disassembly and then soaking in old fashioned, caustic carb cleaner is the best way to get it TOTALLY clean. I hope it works for you.

Good luck,

Thanks. I don't think it needs replacement as the car is not a high miler and the idle is fine. I will know more when I pop it off this weekend...
