Check engine light

For two years now i have used these they seem to cut my cel light to stay off for about 8 to 12 months at. A time. Before that i used to get 1 every 3 or 4 drives. I use the extension with minicat. I have a cappy twin valve, hyperflows , with tubiq headers.

Every time i get one now it seems to be related to the secondary air system.

Not an F355, but when my techs did a belt change with cam timing, all the gaskets in the secondary air system needed replacing. Might be something to check.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.

Thanks taz never really thought of that i wonder can we start the pump without the engine running and i could feel or soap the connections. I guess i could hook 12 volts to the motor? Or whatever voltage its using.

Im not sure of the posting etiquette here but there is a thread on the other f car forum where DaveRocks hooks an external pwer supply up to this pump to check it.

In that case it was already out of the car but I'd bet you could do it in situ to achieve your end.

Let's not corrupt this forum Neil

Yes, you can test the secondary air pump motor with a 12VDC power supply - but as John K had suggested, just use your battery to test it.

In my car, it's hard to hear it because I have no muffler. I created this video and the funny part is, I can hear it in the video but it's hard to hear it standing by the car.

Also Grant, be sure to replace the filter material of the pump.

I've found that the little crankcase breather filters (catch can filters) from K&N fit on the secondary air pump just fine, and do a much better job of filtering

They come in 2 sizes, IIRC 3/4" and 1", and I think I used the smaller of the 2.

Almost looks like Ferrari designed it this way

High mileage, low compression, and missing on a few cylinders.....just like my cars.

That looks pretty trick!
Plus you don't have to remove the assembly to service the filter.

That does look neat kinda like my crankcase breather off my old superbike.

My pump os the other one though and is quite a but differant shaped. Mostly i wanted to test it without the engine running for leaks. I can hear it so i know its pumping. Thanks guys and i did clean. And rebuild it about 5 years ago and it still looks good, i will clean filter again.
