High idle after changing spark plugs

[SiennaLover69]

I just changed out my spark plugs and noticed now that my car is idling high, at like 3000 rpm. I've looked around and haven't found much about it (so im guessing this is probably a dumb question but I just want to be sure before I drive it around a bunch lol).
Is it just idling high because I reset the ecu and will it even out after driving a bit? Is it because the spark plugs gaps are different this time (I gapped them to .030, I dont remember what they were before)?
Also I noticed a bit of what looked like oil in one of the spark plug wells (the first one on the far left of the engine).
it is just idling high and staying consistent at 3000 rpm, its not sputtering or surging.
Thanks for any help!

Did you maybe knock off a vacuum line? Sounds like a vacuum leak

Mine will do that if I accidentally knock the idle stop switch wire off.

No vacuum hoses knocked up, but here is the idle stop switch (i assume this is it lol), but the wire had actually been knocked off for a while, here are a couple pics of it.

Also, would it be safe to drive a bit like this? For just a couple miles?

Your fine, but with a 3k idle it's gonna be interesting.

Check the throttle cable, make sure the throttle isn't getting stuck open, you might have moved the cable and got it stuck.

Yep, that was it, it was the throttle cable!

Thanks for all the help everyone!

Can you elaborate on why the throttle cable was stuck?

We don't want to see you accelerating when you don't intend to.

id bring that spark gap down to .028 also.

My issue turned out to be that the bolts holding down the throttle cable were loose and I guess at some point I somehow moved the throttle cable a bit. I just adjusted it back to where it should be and it was good!

And thanks for the tip on the gap, I honestly wasn't sure what to gap them at so I just when to .030. Just curious but any particular reason why .028 would be best? I'm not quite auto savvy yet lol

Boosted cars need a tighter gap to prevent "blow-out". Basically the cylinder pressure rise too high and the spark can't fire/fires but goes out and you have a misfire.

Bone stock cars work with .028, more power then going down to .022 or so helps. Also the spark will be hotter and ignite better with a tight gap, too tight though and not enough fuel molecules can ignite properly.

for example i run a E3B16G turbo, at 21ish psi and i run a NGK 7 spark plug with a .026 gap.

I need to get mines a tad tighter then... Got my 60 trim at 21psi with .28 on my 7's...

 

[prove_it]

However, E85, race fuel, and ignition system type vary the specs... So there is no perfect car, at least not a universal gap to use that works on all cars. Just guidelines and starting points.

Cool thanks for the info!
