98 CL 3.0 parked not running for over a year. Ran the engine until most of the gas was out changed the fuel filter put injector cleaner in and filled tank up.

Now the rpm go up/down in park and while in drive rpm are higher then before.

Could this be a sensor or gas and suggestions thanks

salogCL

john6699

Not that I can tell just up/down in park and in drive high then normal

this might be silly but is your ac on when you saw this?

Sounds like a sensor, could be the TPS or IACV

john6699

I was thinking sensor.
Yes the AC was on I will try with AC off shortly

john6699

It doesn seem it runs a little ruff and runs the same with AC OFF

john6699

where is the IACV and TPS at can I test or clean them some how

john6699

A friend I mine said to seafoam it, do u think that will fix it.

john6699

Seafoam didn't work here is a youtube on what the car is doing.

did you check what code you have with that check engine light.

john6699

no because It has been on for years it would go on and off for no reason. I took it the dealer and they kept saying it was the gas cap not being tighten.
So I have a feeling it would be a false but tomorrow I will take to see if I can get a code.
I am leaning towards IACV but can't find a good sticky on how to clean it out

I am guessing you didn't take anything apart while it sat did you? the reason I ask is anytime I see something like this the first thing that comes to mind is vacuum leak somewhere. I have not had very many computer cars with all the sensors so I could be way off on this but still figured I would ask if anything that has a seal had been removed for anything at all or loosened while it sat for so long

john6699

no didn't take anything off

john6699

got the TB off but don't know what type of screw the IACV is not torx
any idea
It is 5 points
