All, It was inevitable. I had to adjust the pilot screw 1/2 turn after installing a Uni-filter on my 98 L. What I didn't expect was it falling out after test riding it! I found the screw, put it back in, but needless to say I'm pretty unsure how to get this d-mn thing to run right again. How sensitive is this adjustment? Do I need take it to a mechanic? I've got it to idle o.k., but it pops and dies (more than before adjustment) when downshifting and coming to a stop. I kind of remember the position of the pilot screw before it fell out, but I didn't seat the screw and count how many turns that was. Any advice, other than going to the dealer, on how to remedy this situation is greatly appreciated.
