After a cold start my car idles a little weird. After a few minutes once it warms up it sounds normal but for the first minute or so it kinda searches around for idle everywhere between 1k - 1.4k rpm.

I've heard this is somewhat of a common issue with the LNF, I'm gonna pull my plugs tonight and see what they look like, but does anybody have any other idea's just in case they're fine? The car runs and drives fine once its warmed up but i just want it to idle perfectly lol.

 

Are you tuned?

 

There is the cat warmup cycle that happens during a cold start. It makes the rpms hover around 1k to 1.4k for about a minute right after startup. Could this be it? If so, it's completely normal.

 

stock.

 

I guess it could be that, cant fix anything if i don't get a code anyways. Thanks.

 

There are lots of things that don't produce a code, mine was running so pig rich it had black cloud coming of of the exhaust and there was no codes. Finally after a few days got a random misfire code because the plugs were fouled from running so rich. No O2 codes at all even though it was bad.

 

I'd bet your plugs are starting to go. How many miles are on this set of plugs? Normally they start acting up during cold starts (mornings at 45F or less).

Also what intake are you running and what are your LTFT?
