Replying to: crazybob (Jan 18, 2006 2:16 pm) I also have a 98'GMC Jimmy & have started having these same issues. They started up about 6 mths. ago. I have tried verious things with no luck. The one thing I have been told it might be that I haven't tried yet is the damper actuator, I believe is what it was called. I was reading your post & wondering if you ever resolved your probelms & had any pointers. If so it's much apperciated. Thanks in advance, James M. of OKC, OK
#434 of 511 Need suggestions for 2001 GMCJimmy stalling by valwhite4 Jun 17, 2007 (12:13 pm)
I have a 2001 GMC Jimmy. About 4 months ago, I was driving with my kids to TN and it started stalling on me in the middle of intersections or whenever I needed to slow down. Actually it died most of the time in those situations. Scared me half to death. I put it in the shop and they replaced the fuel filter. Just yesterday it started doing it again. I really need advice. My husband will probably not be able to do the work himself (unless it's really easy) but I'd like to know what's going on so I don't get cheated. Or if someone can give really good instructions, we might try to fix it ourselves. Any help would be much appreciated. Thanks!

Replying to: valwhite4 (Jun 17, 2007 12:13 pm) It could be several things. If the fuel pump is dying and pressure drops it could stall or a clogged fuel filter thus the change. Only way to tell on pump is a pressure test and that requires a $35 Actron or other fuel rail tester that connects to the schreader valve under hood.   Now if this only happens as the vehicle goes to idle it could be the idle air control (IAC) valve on the side of the throttle body and these can get worn or clogged and the air passage blocked - often intermittent and drives you crazy as never happens when in the shop - my 01 did this started every few weeks then more and that was it (at idle).   Then could be related to a sensor but a code should pop or SES light on and Advance and AutoZ read for free.   Then if close to 100k miles cap/rotor/wires/plug time.

Replying to: valwhite4 (Jun 17, 2007 12:13 pm) I had the same problem with my Jimmy - it was something to do with my Distributor (some kind of accelerator cap or something like that). It was not the fuel filter.

#438 of 511 Delayed shift out of park by bruno55 Jul 12, 2007 (8:40 pm)
Hi I have a 2000 Jimmy, We are having a problem when on initial start and any restart from a short stop. It wont shift out of Park until as it would seem to me it has time to build a vacuum back up Im thinking maybe vaccum brake boost? all the lines seem ok and hold a vacuum but hey I might not have a clue.   Any help appreciated bruno

Replying to: hmurph1989 (Jul 12, 2007 4:55 pm) When you turn the key to On (not start) all the dash warning lights come on and the security light also does - that one should go out after like 5 sec and if not then you have a Passlock problem in the steeering column and thats a GM dealer fix. Now if thats out not it so is tshe vehicle really in Park as theres an adjustment on the trans cable at trans - try N position and see or pushing into P again and test.

#441 of 511 Bad Throttle Body Sensor / Wiring? by bravesfan2006 Aug 04, 2007 (6:43 am)
Hi, its a 1995 2-door 4.3L Vortec V6 chevy blazer w/ 150,000mi. When I start the truck, it was alright for about 5 seconds (this morning) and then I can hear clicking about every 3.5 seconds. On the 1st click, the engine throttles down from 700rpm to about 500, and about a half second to a second,(varies slightly) a second click occurs, and it throttles back up to 700rpm (all in idle state) When I am driving, it continues, and you can really feel it. I'm fairly certain it happens more often when you are rolling, but i haven't timed it.   I do generally have to tap the gas to get the truck to start, and wasn't sure if this would be related or not.   I've had this happen once before. It went away after a day or so, so I wasn't able to trouble shoot much. The last time this happened, and this time, the drivers window will raise, but not lower. When you try to lower it, the E-Brake light kicks on in the dash, and the rest of the internal lights dim (have not checked headlights).   Any suggestions would be greatly appreciated!
