Ok guys I sure could use some help here. I have had a noise problem with my car for a while now, and no one seems to be able to figure out what the problem is.
Here goes:
For a while now, while the car is under a light load, the car makes a clattering sound... It is a sound like when we were kids and we put playing cards in the spokes of our bikes. It is most noticable around 1800-2200 rpms, maybe a little higher, especially noticable in 2nd gear but in other gears and rpm ranges also... One thing that lends me to believe that there is a fuel problem is that when sitting for long periods of times, such as over night or when I am at work, it is hard starting... Once started it will start fine, but still has the clattering noise...
Could this be a fuel delivery problem (starvation) causing the clattering noise? The car has dual Cobra pumps installed, but one never knows about what can be going on...
Any help is appreciated
Thanks
