I noticed my hyper 7 tq sport kinda has a high idle after I give it the brakes. The car was running pretty rich when I ran it last and I had the idle turned down as far as it could go without the car dieing when giving it the brakes. So my question is can a improper glow plug cause your idle to be funky? My car has the standard hyper .21 3 port engine in it. To be honest I don't know what kind of plug I was running in it. What should I be running? Should I get a cooler plug? Thanks.

not really, a glow plug is really just to start the car

i would check out the clutch cause if it stalls when you hit the brakes your clutch/spring may be bad.

oh no it doesnt stall now. it only stalls when i turn the idle down too low using the idle screw. im just going to mess around with it today and see what i can do

If your engine uses a standard (non-turbo) plug, the MC-9 should work great. It's pretty much the bench mark standard for glow plugs, plus it's easy to find. The plug can definitely have an effect on the idle. If the plug element is getting white, and especially if the coils are crunched up or sucked down, it will effect the engine. If you want that perfect tune, use a fresh plug. It sounds to me like your bottom end is fat, and you need to lower the idle, but still put a new plug in before fine tuning.

Oh yeah, it's true! Once I get my engine started I like to take the plug out. They last a LOT longer that way!

rule of tumb is the higher percentage fuel you use a colder plug 30% cold-20% hot

Not with Go engines, they run an hot/ultra hot plug even with fuels at 30%. It all really depends though.
