I own a 1995 Chevy Astro with about 148K miles, 4.3 V-6, "W" engine. Over the past several months, the engine has developed a pronounced misfire. Gas mileage has dropped considerably from 20 to 22MPG to just over 16MPG with no change in my driving habits or distances. It's at the point now where it's almost undriveable. I've had it in to my mechanic who has replaced plugs, checked wires (judged okay), fuel filter, and replaced the oxygen sensor. When my mechanic pulled the plugs, although not abnormally worn, he noted that the 3 left bank plugs were "normal" in color while the 3 right bank plugs were very dark...he thought indicating a rich mixture on that side of the engine. I've seen the old parts and can confirm his observations. Previously, in late 1992, the following items were replaced (mileage was about 112K miles): fuel pump & strainer, fuel filter, throttle position sensor, EGR valve, plugs, distributor cap, distributor rotor, distributor ignition control module, ignition coil, plug wires, idle air control valve, fuel injectors and spider, and the engine control PROM. My mechanic now believes there may be a problem with the distributor itself and wants to replace it. I think he's guessing...while I don't necessarily mind that, he's guessing with my checkbook which bothers me in light of the possibile, never ending, perhaps un-necessary replacement of what can be very expensive parts. The mechanic has had the vehicle in his shop for over 2 weeks and there's no end in sight at this point. Is there anyone out there who might be able to give me an idea of what might be wrong here? What could cause the plugs on one side of the engine to look as tho the mixture might be to rich? The service engine light has not come on. My mechanic tells me that the vehicle "computer" has registered no problems. Previous to this, for the most part, the engine has run well inspite of high mileage. Hope someone has a few ideas besides finding a new mechanic! Anything is appreciated. |

I have a 2005 Chevy Venture that I purchased new last year. After a few months, I noticed a mildew smell coming from the vents when I put on the AC or outside vent. After 20 minutes or so the smell seems to go away. I've had the AC and ducts cleaned out twice and the in cabin filter changed twice, but the smell comes back. It seems to happen only during the summer months (in Texas that's almost year round). Does anyone have any suggestions on how I can get this problem corrected? When I take the van in to get the problem fixed, it is only temporary and the smell returns!!

Intermittant problem 2003 Venture/61K miles. Van stalls when attempting to stop. There's not chugging when it stalls. It cranks right back and keeps going. GM mechanics did not find any codes nor could they duplicate. Has anyone experienced this problem/found solution? Past repairs: water pump

| Ok, I jacked the van tried to move the wheel and didn't see any excessive play. I changed the idler arms they were worn and showed some play, but the noise remains. Seems to be coming from the driver side and happens on bumps or uneven road. The noise sounds like something is loose and going to fall off, any ideas or someone who had a similiar problem? | |
