Dont quote me on this, as I don't have any FI setups of my own, but I think there is something where the TPS needs an adjustment.  At any given position, the TPS gives off a certain voltage signal and that it needs to be adjusted to a specific range with the throttle closed.  You'll need a digital multimeter to do it.  My friend who I remember telling me about this isnt home (I just tried calling).  Look around for a procedure for replacing the TPS and you might find the info.  Hope this gets you in the right direction.   -Dave   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Herbert Lumpp Sent: Friday, December 13, 2002 9:31 PM To: [EMAIL PROTECTED] Subject: Re: [Chevelle-List] Non-Chevelle tech question Roger that!   ----- Original Message ----- From: Dean Vandergriff To: [EMAIL PROTECTED] Sent: Friday, December 13, 2002 12:31 PM Subject: RE: [Chevelle-List] Non-Chevelle tech question Herb, If you figure this out let me know.  We've got exactly the same problem on a '90 Ram of my Dad's.  Same deal on the idle adjustment too, you can't change it.    Dean Vandergriff        -----Original Message----- From: Herbert Lumpp [mailto:[EMAIL PROTECTED]] Sent: Friday, December 13, 2002 4:50 PM To: Chevelle List Subject: [Chevelle-List] Non-Chevelle tech question Before I start driving my "new" 87 Jimmy every day, I'd like to fix one small problem, maybe someone on the list can point me in the right direction.    The engine is a TBI 350 (I've never had a TBI before).  It runs great, but occasionally, when you take off from a stop the engine will stall.  Fortunately it starts right up so the stalling is more of a nuisance but I'd still like to fix it.   The previous owner said he replaced the Throttle Position Sensor and rebuilt the distributor.  I think there's something wrong with the TPS or TBI itself.  If I hold the rpm just above idle while holding the brake, it won't stall, but if I just let it idle where it's set it's more likely to stall when I take off.  I was going to raise the idle to see if that helped, but I didn't see an idle adjustment screw.   If anyone has any experience with a TBI or has any suggestions I'd really appreciate it.  Thanks.  cYa-   Herb Lumpp 1966 El Camino ACES 3509, MCC 528 http://users.adelphia.net/~hlump/
