The divorce court judge has ordered me to sell my Typhoon (#1467). Why? Because my ex is a deadbeat who refuses to get a job, hasn't paid her lawyer in 12 months, and in Florida (a "relative need" state, meaning if your ex makes nothing but you work your ass off, you get to basically pay her...

Re: Typhoon suddenly sticks lean Andrew, will try your pressure tester trick, great idea! Dave, wouldn't it run rich in limp home mode instead of lean?

Re: Typhoon suddenly sticks lean Interesting! Any suggestions for a pump brand/model that will more ably support my 50# injectors?

Hi guys, Got a fueling question. I was driving home on the highway about a month ago, and my wideband AFR pegged lean and stayed there until I got home. Since then, when I start it up, it runs fine for about 30 seconds, and then pegs lean again. If I try to drive it anywhere, it starts doing...

Re: Boost solenoid wiring? Thanks for the help, guys. I would guess the wastegate is stock, and has just been port-matched.

Re: Boost solenoid wiring? The documentation I have says it has a "stage 1 upgraded 57mm turbo with clipped turbine wheel for higher exhaust flow and lower backpressure, new bearing, and a ported wastegate." It looks like the system should be rated for 25 psi of boost, but it won't go above 8...

So now that it's clear that the boost control solenoid is entirely missing from my Typhoon, I am trying to figure out whether the solenoid wiring is still around, or if it's missing too. But I can't find any reference to the boost solenoid wiring in the service manual supplement. So I guess I...

Re: TPS report Meant to add, the bad TPS symptoms were that the truck was running a bit rough like the tune was off, and also, whenever I punched the gas, it would hesitate like it was going to stall before it caught and then accelerated properly. Both things fixed now. "Eight, Bob. So that...

Re: Boost is stuck pretty low It looks like a previous owner deleted the boost solenoid. There is just a vacuum line from the turbo down to the wastegate. So, in a truck where the solenoid has been removed, how does boost normally get controlled? Just wondering where to look next. (Also...

I was getting a sporadic Check Engine code of 21 (but this info is also applicable to code 22) and did the Throttle Position Sensor diagnostics in the service manual, but the flowchart is pretty crude and don't tell you much. It turns out the TPS is just a spring-loaded variable resistor. So a...

My boost won't go higher than 7 or 8 psi, even at WOT. I took the attached .CSV log using TunerPro RT: https://docs.google.com/file/d/0B0w-JDdb37U2MG9PRUkzMTdHdms/edit?usp=sharing Chip came from Waller when he rebuilt my engine, and should be matched to the build. I'm pretty new to TunerPro...

Re: Wandering idle For the benefit of posterity, here is the solution to the problem: I noticed that the AFR swings always started out in the direction of lean. I hooked up a fuel pressure gauge to the rail, and the psi didn't change even during the lean stumbling, so this seemed to rule out...

Re: Wandering idle Mobile22, is there any way to test to see if my MAP sensor is working? Or do I just need to throw in a new one and see if it works? STOUT74, IAC looks like it starts to wander around, particularly at time 99 of the .CSV file in my original post. It's stable around 34-35...

Re: Wandering idle Using TunerPro R/T. AFR input is coming into the computer from a wideband sensor, not the original narrowband. Not surging at idle, so much as that it starts out fine, but then gets lean for awhile, then overcompensates by going way too, then overcompensates by going way...

Re: Wandering idle It was working fine before with this same computer code and same engine configuration, not really sure what caused this problem to emerge. Now I can't even drive it, sometimes it stalls out even when I'm just slowing down.
