Why I LOVE my 4.2--solved whistle problem.

I just [img]/wwwthreads_images/icons/smile.gif[/img]love my 4.2, A little bit of tweaking is all it took to get the whistling to stop. Actualy it wasn't anything that I did, it was a friends dad who got it to stop. I re-configured my air intake tube, didn't work, retourqued the intake and exaust manifold bolts, didn't work. then I drove it over to a friends house. His dad built engines for John Deer for a living for about 20 yrs. His dad played with the air intake, then the throttle cable. After he was done messing with the throttle cable it stopped whistling. Aparently the little plastic sleve at the end of the cable was just out of place and kept the plate(sorry don't know the name) that controls the airflow into the engine just a little open.

One last(hopefully) question about the MPI. I've put 300 miles on the engine so far, when will the RPM's slow down. Right now it idles between 2 and 2.5k.[img]/wwwthreads_images/icons/crazy.gif[/img]. That is the last thing that I am worried about.

Thanks guys(and gals if you are out there)[img]/wwwthreads_images/icons/cool.gif[/img]
