Thanks, Tom. We tried some of that the other day.
First a 9" straight piece, then just 3 inches plus the filter.The engine would still miss and scatter off idle, once warmed up.
I "fixed" ,or fooled, i should say, that problem by taking the thermister / sender out of the water jacket and just having it plugged in and fastened outside the engine..
Now, the only problem is that when power shifted into 2nd, it sounds like I'm lifting the gas, but I'm not. I tried it at 6000, then again at 5500..Same deal.
I must mention, we're at 4600 ' , with a d.a. of 7300' .. I'm thinking that there's just not enough oxygen available in the intake when the shift pulls it down.
We're going to try it next week at Chandler, where the d.a. will be about half that.
Any ideas about this issue, anyone?
It is MAF, open loop, stock computer.
