So my 1991 RWD ext Astro with just about 187k miles on it has had an odd vibration only occurring while in gear at a complete stop? Not sure where its coming from but feels more towards my front end near the dog house almost. The vibrations usually do not start until the van is completely warmed up ...

V8FamVan,

Thank you! I was completely lost as I looked for the MAS and did not see anything!

186xxx on the van! I wish it only had 86xxx!

Just noticed my image before did not load. This is what my gauge climbs past as i start climbing hills. It has only so far come up JUST below the yellow marker. Not sure if that is normal? I just got a new T-Stat to see if its a simple fix. http://i1201.photobucket.com/albums/bb353/Derek939/photo.jp...

Awesome! So I just need to pull my air filter housing out and lift up on the throttle body and this will be down there?

Thanks again!

Derek

I like the idea astrophysics! I usually roll around with one downhill bike and one XC/Freeride bike. Usually both together take up from the sliding door to the edge of the passenger seat. Im hoping to make the bed here shortly, also contemplating ripping out my carpet and having my buddy weld in som...

I've been searching through the site looking for ideas to build a bed in my van. It's a 91 rwd ext with the rear seats takin out. Lately I've been building Mountain Bike trails for skibowl so I stay up on Mt. Hood for 3 days of the week camping out of the van. I've just been using a fold up cot beca...

Just curious so I can go in and do this... Where is the mass airflow sensor located?

Also I took off the radiator cap and started the engine but within 1 minute the fluid
Level started raising and overflowing slowly. Is that normal?

Thanks guys!!

Im gonna go check for that here is just an hour or so Gary, thank you! Never hurts to check at least. And no the radiator has always sat just below the cap and never usually leaks. There is on small leak on the top of the engine block where you put oil into the engine it has a brace that runs down a...

Thank you everyone for the tips! Its highly appreciated! The Coolant level is a bit high, pretty much an inch or two down with the radiator cap off. The van does just fine around town its just once it hits hills I lose a lot power it feels like then after about 5 or 10 minutes of climbing(I work on ...

So I'm new to this site, you guys rock! This site is very helpful. But I have a 1991 astro rwd that wants to overheat when going up hills. It drops back down after just 5 mins or so but it worries me being that I have the heater fully blasted and it stills is on the verge when climbing hills. Why wo...
