I have a 1991 chevy s-10 w about 120k miles. The truck has always run very smoothly. After seeing a noticeable leak of coolant I flushed out the radiator. After refilling and waiting to observe the leak I noticed that there wasn't a leak anymore.However, now the car was idling very roughly. When driving there was now a hesitation and stuttering in the acceleration. Additionally there is a knocking sound from the (air)filter area and the engine shakes a little. The car idles very shakily but doesn't conk out.

I recieved an letter from GM today about my tail gate cables... Basically telling me that if I need to replace them, to take it to the dealer and it will be taken care of.... I guess I'll head in and have it taken care of. It will also give me the opportunity to ask them about the tranny flush after 100K that I have been meaning to get to. Plus my Impala has a defective horn that needs looking at which because it is still less than 3 years old and only has 20K miles on it shouldn't be a problem to have taken care of. I also need to have them see if they can do anything about the gap between the dash top and dash front.... All minor ticky tacky things which don't really bother me, but I guess I should just get them taken care of.

I have a 2001 S-10, Crew Cab. You can have the radio on and the display says it is on and receiving a signal. You can not hear it. You turn up and down the volume and still nothing coming out of speakers. Sometimes you can turn the truck a certain way the speakers may come on, sometime it is opening or closing one of the doors, a person may just sit on a seat, hit a bump in the road. It may blast you out of the truck when it comes on. Sometimes when it comes on the speakers appear to increase in volume right after you can hear them. It has gone as long as two months and not play then comes on for several seconds or may play normally for a week. Any suggestions on how to try and chase down the problem. It is very annoying. The radio has a CD Player and a remote cassette player with it. All was factory installed.

Replying to: thazard (Sep 12, 2006 4:44 am) Checked voltage to ICM and coils, never looses voltage. Had ICM checked out at auto parts store. Tested four times in a row to make sure unit was warm. Tested good all four times. Checked coils as per manual with an ohm meter, both checked good. Checked crank sensor as per manual, checked good. Plug wire resistance checked within specifications but varied a lot. Plugs looked ok. I will replace them both for good measure. HELP! Please!

| Today windows were fogged up so I switched to defrost setting. After windows cleared I switched back to AC. Noticed I was not feeling cool air. All the air was coming out of defrost vent. Fan was running and the air was cold. Just not coming out of the main vents. The truck has 82000 miles and still runs good. Anyone have any ideas for what might be wrong? Everything had been working fine prior to this. Thanks Bud | |

Replying to: alvinl (Sep 16, 2006 6:39 am) Using these as clues (and assuming you are not shorting out on multiple speaker wires. ...) I'd say the issue is not in the speakers/doors - but at the Radio (Common Speaker connector is loose or dirty/bad connection - Especially and common return wire for the speakers (depending on series/parallel speaker hook up)). Power and Ground seems ok as it's always on ... Therfore, I'd check the connectors on the back of the unit - possibly unplug and re-plug the connectors. You may be able to get at these from under the dash - but you may have to go through the front (remove the radio/Dash bezel, etc.). Also check to see if you can get there through the Glove box - you may be able to remove the box liner and get in fromthe side. (Be careful ! /you do not want to launch the Air bag !!) Another thought may not apply to your vehile - but the later models also have "SCV" or speed control volume (the faster you go the greater the volume to compensate for road noise.). This may be "Muting" volume if disconnected ?? (Just a thought!) good Luck and tell us wht you find !!! So there are a number of cables for the Radio (Lights (dim at night when the head lights are on), Speed sensor wire, Power, Ground and of couse the speaker outputs.

Replying to: thazard (Sep 16, 2006 2:01 pm) You've checked a lot - and all looks good (I feel for you ..). You comment on the no spark gave me a thought. If it was going to stop for a problem - it should give an error code - so maybe there is none (to the computer)??. Can you check the "On" wire circuit from the key switch to the computer and the IGN on signal from the computer to the ICM ??? Perhaps it thinks you shut off the key and is just shutting down ??? (i.e. intermittant contact/wire, etc.) |

Replying to: boyce (Sep 17, 2006 9:15 am) Just continue to drive it for a while (do a few rough roads as well) and occasionlly during your drives cycle the selector switch through each setting (letting it stay at each stop for a few minutes.) It might loosen up. alternatively - you can check for vaccum at the vaccum motors - but you''d have to get under the dash for that - also check the vaccum lines for cracks and splits - especially at the ends.... Get a Chassis manual from GM (or Try alldata.com on the net) and you can see where the vaccum motors are and how to get to them .... |
