My previous 2001 AWD Safari van did that. re: It too had consistant idle. My local mechanic investigated and discovered its throttle body was "gummed up" with too much dirt and crud. He cleaned this area with engine cleaner spray and it worked great afterwards. As a suggestion, remove your van's inner cabin engine cover (aka: "dog house") and do a good visual inspection of the engine's throttle control body area. If needed, do clean this engine area with lots of engine cleaner stuff as well.
 
Hope this helps...

1995 Chev Astro No Start No Crank by minjon
May 16, 2009 (3:44 pm)

I've read through previous posts but none seem to exactly match my problem. It is:
1) Intermittent crank/no crank condition.
2) May crank 6 times successfully, then no crank condition.
3) After leaving the vehicle overnight it will crank 1 or more times, then no crank condition.
4) Battery, cables, connections ok (including at starter).
5) When no crank, I do have lights, hear fuel pump run to pressurize fuel lines, etc.
6) When no crank, the solenoid is silent (no click, click, click).
7) When does crank will immediately start engine
8) Replaced the ignition switch already.
9) Starter/solenoid assembly about 1-1/2 years old.
10) Is there a mechanical relay between the ignition switch and the solenoid? If so, where is it located?
11) I have purchased a new starter, but hesitate to install it if there is a bad relay. This Astro does not have a fuse block under the hood as later models did.
12) What have I missed???
Thanks!

Hi Everyone,
I have found the problem with this van and the bucking issue that it was having. First, I would have to say, that there were actually two problems. I replaced the air mass meter (found a brand new one on ebay in January for $60). This did correct the issue that I was having with bucking at 55 mpg or faster, however, I was still having a problem with starting the van. Up until about 2 yrs ago it started on the first crank everytime (I've owned this van for over 120k miles and 5 yrs)--however since then it has always been that I had to give it one crank, turn the key back then hit it again and it would always start. Last week, however, the van began to miss very badly on one particular morning and it then stalled and would not restart. It turns out that there was no gas flowing--the fuel filter was good--problem was that the fule pump was shot. I replaced that and it starts like it did when I first bought it--on the first crank, everytime.

O2 sensor Bank 2 senor 1 removal 1997 Safari by navyblue

I'm pulling code P0152 high voltage on Bank 2 sensor 1. Any ideas on what would cause that? Also how in the world would you get a 7/8 wrench in there to remove it? All books call for three sensors, 2 upstream and one downstream of the convertor but the drawing I'm looking at clearly identifies three upstream and is verified on my van? ^*$&# Any experience? Thanks

If your 97 Safari is like my 97 Astro you might want to take a look at the guide that I very recently posted on this forum with a link to some photos I took during the disassembly/reassembly process.
 
http://www.carspace.com/guides/
 
My 97 Astro has two "upstream" O2 sensors, and two "downstream" sensors. The first of the two downstream sensors is the one just before the catalytic converter. Each set of sensors has a different type of connector on it. I didn't bother trying to get to the sensors with the exhaust in place because I was replacing the cat as well. As near as I can tell, your best bet is to drop the exhaust down by removing the three bolts on each side that connect the pipes to the exhaust manifolds. You don't need to completely remove the exhaust, but just drop it down in order to access the sensors. The thing to watch out for is that one or more of the studs could break off while loosening the nuts. This is not all that uncommon. If one does break, then your in for a headache trying to remove the broken stud. Have a back-up plan ready. Plan for the worst, hope for the best. Good luck.

Excellent documentation. I unbolted the exhaust at the manifold, screw jacked the tranny to hold in place, removed the "cross brace" and dropped the exhaust to get decent access to the sensor. A couple of the bolts were a little tricky but all in all, not a bad job. A whole lot of work for a two minute replacement of the actual O2 sensor. Putting it on a lift was a great help. Thank you Navy MWR! Thanks for the help.

I did the same thing with Advance Auto and got a military discount on top! Life is good. I could get the socket on but couldn't get any leverage so I dropped the exhaust with little difficulty. Thanks for the tip.

Love to hear a success story. Good for you. Nice to have access to a lift, wish I could say the same. Go Navy!

Replace Inside Door Handle 03 Astro by rayocon
Jul 01, 2009 (10:22 am)
Reply
I'm trying to replace the passenger side inside door handle on an 03 Astro. I've gotten down to the broken handle and there is a metal pin going down the center. I need to remove this pin in order to install the new handle. Problem is there are 2 pieces of metal protruding at the bottom (like a cotter pin) which prevents me from removing the pin. Anyone know how to remove this? Thanks.
