I am using Taylor wires and tried both the stock plugs and the ngks with no difference between them. I have looked high and low for a vac leak and could find none, but it doesn't mean I didn't miss it. Thanks for the info though.

truckins10 Did you ever get this issue resolved? My truck has a similar problem but not quite as bad. I can adjust my fp up to get in the 128 range under throttle but I run very rich at idle. If I lower it to get my idle BLM to 128 under throttle it goes way up.

I was under the impression that the BLM values should be about 128 all the time. Not ever having owned one of these trucks before I don't know what to consider normal for a stock truck. So based on my numbers which fp is better?

I have been having some idling problems with my truck. With the base fuel pressure set to 40 psi it idles rough and the tach hunts. If I turn down the fp to 36 psi it idles fine. Using turbo link I get the following BLM data: 36 psi base, 128 at idle and 144-150 under throttle. 40 psi base, 112...

Thats perfect. Thanks alot.

Which port is the vent on the boost control solenoid?

I have been chasing this problem with my truck for quite some time now. My truck idles fine in park when the engine is first started. After driving it a couple of miles it idles fine in drive but if you shift it into park/neutral it will begin to surge. Put it back into drive and it idles fine...

My truck seems to have a similar problem to yours Falco. Does your idle hunt more in park than drive? Mine does. This is true on my truck. But I don't know what to make of it. I hope you figure yours out maybee it will give some insight as to what is wrong with mine.

Yea, I don't really think its my problem either. I checked the ECM and I have the stock chip. In drive it idles at 650 +_ 25 RPM. In park it it swings anywhere from 600 to 925. I'm getting frustrated with this thing, good thing its not my daily driver.

I am sorry I was not very clear. I meant the front rim differnce between the Syclone and Typhoon, there are two different part numbers for them. I was just curious as to why. I thought the wheels were the same between the two trucks.

Are the rims the same? I see on the sytyauthority web site that there are different part numbers for the front rims.

I have pulled and cleaned the IAC and passages, looked fairly clean to start with. Put it all back together same deal. IAC counts are between 30 and 40 in park and a little higher in drive. Adjusted the throttle stop so they were about 20 in park(??). Same problem. I also checked my fuel...

Thanks for the replys. What is the difference between the truck idleing in park vs drive? It seems to idle fine in drive. I have replaced all of my ingintion components, checked my timing. I have also checked for vacuum leaks via the bike tube trick, but here is where I have another question...

Thanks, swapping parts can get expensive fast.

Thanks for the reply. The idle surging in park is normal? Or the injector pulse width jumping? Having never driven one of these trucks before I have no idea.
