Hi everyone, these plugs were in the car for maybe 200 miles or less. Ones cylinder looks over heating? Currently having idling issues (dies at stops when engine hot), changed coils, new plugs (in pics) , map wack, IAC clean.... trying to do the more commons ones first. Now im thinking fpr or fuel filter? Since the car only drives 6 months or less per year. Forgot to mention, it smells like is running rich even the car is cold/ first start and miss fire( no cel). Anyone had similar issues or suggestions what else i should do next?

 

Check your o2 voltage. There's no fuel filter save a sock on the pump.

Injectors can go bad on these cars if not driven for long periods.

 

You using a fuel stabilizer? Might help?

When I lived in NE Ohio my car sat indoors November - April due to cold weather and snow. I used the same marine fuel stabilizer I use in my boats which were also out of service for the same period and never experienced this. I can find out what it was if there's any interest but it's commonly available. Sample of one (1) is hardly scientific but it works for me.

I didn't realize we didn't have a fuel filter, does it need to be replaced from time to time?

 

Separate fuel filters are getting uncommon. The "sock" in the fuel tank works just fine.

yes i was talking about the "sock" has anyone cleaned it and resolve their issues? I saw on utube 1 guy did that,clean their tank n solve the rough idling. I'm wondering if i can just use those gas/ injectors cleaner stuff to clean it without having to get into the gas tank.
btw, i had my injectors clean and tested along with the new coils n plugs

 

The S2000 fuel pump is on top of the fuel tank and accessible via the trunk once you remove the spare tire and unclip the carpeting. Easy enough to remove it and check the fuel filter. If it's dirty I'd find a way to clean the fuel tank. If I was going to that trouble I'd put in a new filter even if it was clean. These are vehicle specific. I know the DBW cars are different.

There is definitely fuel a filter besides the sock, if you are down there might as well replace both.
The filter sits inside the plastic housing and cant really be checked unless you cut it open.
Don't really seem like this is the problem here though but you never know.

 

Exactly. It´s the new style, the filter sits inside a plastic housing in the tank. Wrenched at the BMW Nine T Bike of a friend last winter, same design.

 

The plugs look good to me, one cylinder is running a tad more rich than the others, or creating more soot, not entirely uncommon as the air flow is not equal between cylinders with the oem manifold. I don't think one cylinder is running much hotter than the others, not to any degree of it being an issue. Cylinders 2 and 3 do run hotter than the other two cyls. which is normal, and cylinder 4 is always a bit different than the other three. I think everything looks normal there.

I always suggest running Redline fuel injector cleaner once per year, it is the best product out there that actually works with it containing the highest levels of PEA, it is also an upper cylinder lubricant which helps the valves too. 1 bottle does 2 tanks on the S2000. At 80k miles my intake ports and intake valves didn't have a single deposit on them, I was shocked how clean things were when I opened up the top end, and I ran Redline once per year in my car.
