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.

Any one have a good path to connect the black battery wire of Prodigy brake controller to the battery? Is it drill a hole in the fire wall and snake one through or is the connection point under the dash? Thanks. Don

Replying to: cob (Mar 21, 2006 4:37 pm) Thanks for pointing out the White wire from the brake pedal connector. I’ve completed the hookup, including power to the controller. Now I’ll have to attach the camper and synch. the controller braking. -gary

Replying to: lind777 (Mar 25, 2006 3:02 pm) I’ve previously thanked Cob for the white wire brake pedal info. I’ve got a ’98 Safari, so it should be the same. Sounds like your doing what I just completed. I’ve got the Voyager controller installed and just completed the installation. 1 The path for the battery hookup is thru the Speedometer cable. You’ll see a black cable running down from the dash into the firewall. I used a fairly stiff feeder aluminum wire, (I think it is wire that holds up suspended ceiling). It took me 3 or 4 times (almost ready to give up) but finally fed it thru the grommet type hole that the cable is going thru. Under the hood you’ll have to see where the cable is to locate the feeder wire. I taped black and white wires to pull thru and eventually get enough to attach to the battery. 2 The Napa friend sold me 2 battery cable replacement lugs. These plugs have screws on the end to attach wire connectors. I unscrewed the cables (you’ll lose the radio presets) and worked out the plug connectors from the cables and replaced them with the new connectors. This will allow a secure connection for the brake controller power wire. I’ll stop here to see how you do -gary |

Replying to: lind777 (Mar 25, 2006 3:02 pm) I reread your message indicating if there was a connection point under the dash. My Napa friend never told me of any accessory connection, rather fish the wires through the Speedometer cable gromet firewall. It would make the conection easier if there was such a connection under the dash for the controller. Maybe someone else will reply with an answer. -gary

Replying to: marlin39 (Nov 12, 2005 11:02 am) These vans are one the worst to R&R an engine.  If you need detailed instructions, you can goto alldata.com and sign up for there automotive repair and diagnostic info on line, the cost for 1 vehicle is only like $20.00, and I personally have used alldata for approx 10-15 years now and it is a great site. good luck..
