Replying to: cptlocksley (Apr 19, 2009 7:58 am) That's a pretty drastic solution---you should definitely check the timing mechanisms and also throw in some premium gas and see how that helps.

Replying to: cptlocksley (Apr 19, 2009 6:50 am) The 3 Liter motors almost all ping. Not much to do about it but use higher octane fuel. When a 4 Liter pings, it means the bolts holding the intake down have loosen up. This allow air to be pulled into the intake, leans out the mixture, and this causes ping. Start in the center and criss-cross tightening up the intake manifold bolts. I think they are about 9mm or so. A 1/4 inch drive with flex connector and extensions of various lengths will also be needed. I don't know the torque needed. Just snug them up, you are going to find several that are loose. This happened on my 94. I bet it's your problem. Otherwise, 4 Liter Rangers do not ping.

Geo Prism. Says vibrates/shakes for abourt 20 minutes until fully warmed up. Then okay. Took to Autozone, many possiblities they say... she mentions a sensor. Said one mechanic lifted the front left bumper and it stopped shaking. Idle air control sensor? Replies to this message: Mr_Shiftright (Apr 22, 2009 5:49 am) jipster (Apr 22, 2009 9:26 am)

Replying to: jipster (Apr 21, 2009 6:24 pm) I'd look for a vacuum leak before guessing about sensors. As the engine warms up, very often a vacuum leak will seal as the metal expands. Or some device could be sucking/leaking vacuum until a certain temp is reached and then shuts itself off. You might also scan the car for trouble codes.

#4801 of 4968 refrigerant leak detectors by ed_in_pa May 01, 2009 (6:01 pm)
I am a bit of an test instrument geek (more lab than real world) a friend of mine has a repair shop and is looking to purchase a refrigerant leak tester- he has been looking at the Inficon T-Dek, a Fieldpiece unit and a couple from Bacharach- (H10G and H10PM)...if anyone has a feeling of which of these or even another unit- is the best- i would love some real world input- i can and will do the spec comparison- just tying to understand what works best in real use- THANKS
#4802 of 4968 Turn signal problem - can you help me? by alternator May 03, 2009 (4:19 am)
None of the turn signal bulbs in my 2005 Chevrolet Cavalier respond to my turn signal lever (no light-up and no clicking), but all four bulbs do respond to my hazard switch (they light-up and click-click). What could cause this? Aren't these the same bulbs? Doesn't the same flasher unit operate from the turn-signal lever and from the hazard switch? Is the flasher unit located where an ordinary mortal can remove it for replacement?

Replying to: alternator (May 03, 2009 4:19 am) I checked the fuse block and noticed that the turn signals and the hazard warning were separately fused I went to Wal-Mart and got a new 10 amp mini-fuse (I still have a number of regular-size fuses and didn't realize they don't use those in new cars now) Changed fuse, turn signals work fine. I wonder what caused that fuse to blow. There was no lightning or any other suspicious event near the time the turn signals stopped working I will still be sticking my head under the dashboard to see where, and how accessible, the flasher unit is Replies to this message: kiawah (May 03, 2009 1:26 pm) alternator (May 04, 2009 1:09 pm) euphonium (May 05, 2009 8:53 am) and 3 more...

Replying to: alternator (May 03, 2009 11:49 am) Look closely at your bulbs, you could have a broken filament flopping around as you hit bumps. Replies to this message: alternator (May 04, 2009 1:09 pm) euphonium (May 05, 2009 8:53 am) alternator (May 13, 2009 6:06 am) and 2 more...
