94 del sol Idles up and Down. Help!?
Hey fellow honda heads, I just noticed a couple of things about my ride today. I run a 94 del sol with an LS swap in it. I just noticed that the whole car shakes a little while the AC is on. Also when at idle the revs go up a little and then back down form 500 - 1000 rpm after it warms up a bit. She just had new mounts put on so i'm not sure whats going on. Is the idling an issue or is that pretty standard?

yeah this is a very common idling issue on the del sols...if it idles up and down at start up and then smooths out at operating temp then it is you FITV.. if it idles good at start and then strat the bouncing at operating temp then it is you IACV...

you are right it is a general issue with the honda engines.... not just sol's... was just using the cars name and not a general term as Honda's... MB

that logic sounds good haha, yes there is a light on above the car door indicator its a red "S" and i havent been able to figure out what that is. other than that there is no literal check engine light.

ok well a red "s" hmm i know the light srs that is safety restraint system. and a cel is orange. looks like a motor. idk what the red "s" is but either way cel's are orange if no cels the other light makes no diff of cars performance.

When you turn the key to ON(II), does the CEL illuminate for 2 seconds and then turn off?
For the surging idle, you definitely want to start by cleaning the IACV, as well as the FITV if you have one. Two other things to try are to check for an intake air/vacuum leak and to bleed the cooling system.

Re: 94 del sol Idles up and Down. Help!?
AHH ok i thought you meant "is there a cel that stays on" I completely misread the post sry.. haha, there is a cel that comes on for a second when i first start up the cel does come on and flash for a second and go away. Is the number of flashes when it starts super important? i heard about jumping the connector and reading the number of flashes as a diagnostic but just on regular start up does the number of flashes or time that it stays on have any symbolism?
