Idle!!!!!!!!

[srt8-in-largo]

Probably; if you try them post your impressions.

The reason I don't switch brands is because I know exactly what heat range of NGK plugs came in my car from the factory; 5. Not to mention NGK is one of the best. Point being is that Bosch 5 is not necessarily an NGK 5, for example, and vice versa; different companies can use different heat range scales. Plus by staying with OEM brand you don't need to worry about possible differences in reach or other fitment items. If you do an application check on the website its probably fine.

An interval really doesn't exist for the PCV valve, just replace it when its bad. If you want an interval... replace every 50,000 miles. And its cheap and easy enough I wouldn't go more than 100,000 miles on one.

according to maitenance schedule, PCV valve should be inspected and replaced as necessary every 30,000 miles.

Thanks for all then info guys. I'm just trying to find the right place to buy oem plugs. Also I'm nervous with the one plug that wouldn't come out. The car was cold but I did t wanna crank to hard and snap it in half. Anyway to help get it out ? Also how do you check the PVC Valve to see if it's bad ?

How often do people change the plug wires on there cars? I'm also having a ruff idle lately on my car, I have a pid selected on my trinity that says misfire counts and that fluctuates alot,one day at a red light it hit 7 times lol.

There's not much that can be said here, put a wrench on it and turn it. If you don't want to turn it yourself have a shop do it and take the responsibility.

I don't think people change them that often, if at all. You got me curious about mine now.

i don't think anyone on this forum drives within the parameters of schedule A.

The Bosch 6711 has a different heat range rating than the OEM NGK plugs so you may want to "read" a few of the new plugs after some driving to make sure they have good insulator color (light tan). You don't want them running too hot or too cold.

can always try this.

Thanks for all the info guys. Probably just gonna swap my plugs but I'm waiting to find a good price on oem or close to oem plugs. These things are CRaZY exspensive !!!!!!

Since we are talking about idle speed - My SRT typically idles at about 700rpm in Drive with a warmed up engine. Sometimes, I'll come to a stoplight and the idle will be at 650rpm instead of the normal 700. If I bump it to Neutral and then back to Drive, the idle will come back up to 700. Does anyone else notice this? It does this with or without the Predator tune installed.
