If you want to check for a dc pulse on a particular circuit, what do you use. I'm talking low-end tester. I guess if you have a dmm with a tach--dwell--duty cycle--frequency setting, I guess any of these will react to a dc pulse. Also, I believe a digital logic probe has a pulse setting that will...

I 'm contemplating purchasing an oscilloscope for amateur radio uses and general electronics tinkering etc. But I also enjoy working on automotive electronic systems etc. My question is, can a regular oscilloscope be just as useful when diagnosing automotive electronic problems such as fuel...

165,000 miles. My Buick stalls intermittently. It bagan when I parked it at the store, came back out ten minutes later and it would crank, but not fire. Ten minutes after that it started and ran perfectly. Took it into a mechanic, and naturally he couldn't duplicate the problem or find a code. ...

Hi, I am in a dilemma and unable to come to a conclusion, so I thought of seeking advise with some of the knowledgeable people here. I am planning to buy a used car. I was looking for a 2000/2001/2002 camry that I could buy in a $7.5K - $10.5K range. I wanted to buy a low mileage car, with less...

Hey folks, I recently inherited a Stiga riding lawnmower with a Briggs and Stratton 10HP engine. After dismantling and cleaning the carburetor, I have been able to get her started, but I'm having problems keeping her going at lower engine speeds. In order to start it, i need to remove the airbox...

Just wondering if anyone has had any experience with the 4A- series of engines (SOHC 8V) found in Corollas from 83(?) - 91 and Novas. I've been told that its an iron horse from one mech and that its a piece of crap from another.

This is the link between the lock cylinder and the ignition switch. It seems - from responses received from other sources -that the easiest way to replace it is to replace the steering column. Anyone here got any thoughts? Thanks in advance. BTW, I'm not doubting anyone elses valued...

I had to replace the oil pressure sensor on my 1994 Mazda MPV. Because the protective boot for the connecting wire had hardened up over the years I kind of mangled the connector when I removed it (it looks like the connector was designed to be disconnected by pulling the boot off of the sensor -...

I recently bought a '91 Sable and found the windsheild fluid pump doesn't appear to work. The wipers work (which I assume means the fuse is good), there's a full tank of fluid, but I push the button in and I hear/see nothing. If I assume that the wiring is okay and that the pump is damaged,...

Specs: 1998 ford explorer, 4.0, SOHC I notice this noise slightly all the time. There is a slight hiss, but I'm unable to determine the source. It becomes much more noticable when I change the position (accelerate or decelerate) of the gas pedal on a smooth section of hi-way. It also does the same...

It's a '94 aerostar, 95K miles. For about a month, the ABS light comes on at random. But braking was unaffected. Then yesterday I was braking because a speed bump was coming and the rear wheel skidded. I think it was the left, but could have been both. Already going too slow to affect anything. ...

Hi, I've recently noticed a loss of power (slow accelerations and low top speed - hard to get over 65-70mph) so I've removed the spark plugs and checked compression. ALl cylinders are ok except one which has compression 1-2 bar above the rest, on that cylinder there is a lot of clean oil (oil...

I am looking for a daily driver that is a 4x4 and not too hard on mileage. I drive about 50 miles a day mostly by myself but ocassionally need to carry the wife and two kids short distances. (Two car seats). I drove a jeep grand cherokee and loved it. (a 2001). I have seen the Suburus are awd and...

sorry for barging in on your group but the answers to life's most important questions can usually be found in usenet. so... I don't know much about cars but I know when my car is messed up. I think it's a fairly simple problem but no one has figured it out. The problem started when I took my 2003...

Two questions today: 1. Tranny problem - My 3 speed THM 400 (1985 Chevy pickup) hesitates during the 2 - 3 shift. It seems like it stays in both gears until I lift my foot a little to "baby" it thru the shift. I have a tranny temp gage and the problem does not vary with tranny temp.

There's work going on to make a variable cycle engine- one that can run as a 4 stoke for economy and a 2 stroke for power- looks like they're going to use a valved 4 stroke and go with a double speed for the2 stroke valve ops.If there is still some mixing of the exhaust/intake mix, would the...

I am looking for a good reliable used one that I can sometimes get the family in is a 4x4 and not too hard on mileage. I plan to drive whatever I get for the next 10 years or more. I drove and feel in love with a 2000 Jeep Grand Cerokee. Are these any good? Is there a difference between the 6 and 8...

Hello, We have moved from TX to NC and are planning to stay here for about 6 months. Yesterday we registered our car here and tried to have our car inspected but got a rejection because our back window is too dark and does not meet the state requirement of 35%. (the side windows are fine) Since...
