So on the fiancee's car she had a sticky throttle pedal. I cleaned the throttle body the best I could without removing it, and it still stuck at idle, making for sometimes jerky starts.

I figured if I bumped the idle speed up just a little bit from ~800rpm (as it was at 150k miles and whatever work was done with it in the past) to just enough where the throttle didn't stick.

Well, the 7mm nut loosened the idle speed adjustment screw as well, so I lost where I was at. I set it at just under 1000rpm, and it was fine with no pedal stick at idle. I adjust the throttle cable as I had to remove it for idle speed screw access, and adjust it so there's minimum slack in it without opening the throttle when I put it 'back together' (4 air filter clips and a few nuts... anyways).

Fiancee takes car back, and ses light comes on. Idle 'surges' from normal to 1500 and back when in park and stuff, and when she goes from drive to park or neutral it jumps to 2000 then does the 1k-1500-1k idle surge thing.

I'm not sure if it's from the fuel I topped the car off with before she took her car back, if the gascap is tight, or is the computer is spazzing out from a slightly higher idle speed and a not slacky throttle cable?

She took the car back Sunday evening, and the light came on tonight, after ~90 miles of driving.

She (and her parents) want her to take it to a shop and throw money at it, I think she should just drive it as is and let me take it get the code(s) read and fix them and fix it if I feel competent (I do 98% of all my own automotive work). I dunno what to do.

I guess this is part tech, and part 'Dr. Phil'

Fire, flame, and comment away. I'm not a huge Honda guy, but I appreciate the help.

do the boring threads get no love? Maybe I need to post a picture....


there... maybe that will get some ideas going.

Does anyone think what I did caused a code? Doesn't seem like it, but OBD2 cars like to get spazzy about little stuff.
