    Did you have these problems with your car before you had the work done or did it start afterwords?

    FYI, the most common problem that causes high idle is an air leak somewhere in the engine, but it could be a number of other things.

    Do you know if anything was done to the TPS (Throttle Position Sensor) ? This would cause a similar problem.

    Let me know. Thanks

Try pulling the engine coolant temp sensor, They often crack not sure why but the ceramic tip cracks makes the car hard to start, the car's idle may race while shifting gears, and often smokes. The sensor is on the right side of the engine when looking at it on the head. Easy to change and get too

My used Saturn ion 2003 making loud clicking noise when idling and not accelerating

You buy a 10 year old car that isn't even made anymore
and know it has issues

Do you not have a repair shop you use for many years that has
been around for decades

You need a shop to go thru the entire car & fix ALL problems
regardless of cost,not us guessing at things

Not to get up to speed could be a gas filter ,most likely worn
out & blocked exhaust converter & I could write a book

All it's issues can be diagnosed & you should spend about $1500
if ALL problems are properly tested & resolved

Now you got the entire suspension,all fluids,brakes,tires & on & on

When I buy any vehicle I put it on stands for 3 weeks min & go thru it

On a new car i spend a week a year going thru the entire car

I take brakes apart every year

I check all data every 4 months with professional scan tool software

High idle

It's probably one of two things , a vacum leak or a bad ground.

Idles high & throttle sticks sometimes when stopping

Sticking throttle. Clean and loosen the sticking parts.

2004 saturn ion idles to fast

may need to check your vacuum lines. Your car probably has a MAP senor (Manifold absolute pressure) so if you have some sort of leak into your intake manifold it will raise engine rpm to compinsate for the extra air.

Idle speed that high usually indicates a vacuum leak somewhere. Check every vacuum line and hose and connection you can find for loose or damaged hoses. Also make sure there's not something causing the throttle linkage or pedal to stick or be in a bind.

Weird idle when clutch is disengaged

Sounds like a bad idle air motor (That controls idle) But you must pull compiter codes first (The computr tells it what to do)

Question? is the engine's heat normal, if not there's sensor that boosts idle when the engine is cold

If you removed the thrmostat, put it back in.FIRST
