Question Asked: Rough Idle. 1/8" gap between the throttle body and the upper intake manifold.
October 15, 2012, 08:52 AM
Every time there is a stop light, the car vibrates and shakes unless I step on the gas a little bit. I'd love to fix this.
Question Answered: cruise control
October 15, 2012, 09:21 AM
I have same problem. I think it is just the switch in the steering wheel. I read that you can pull it out with two flathead screwdrivers on each side and put in a new one by sticking it in the old hole.
Question Answered: brake pads semi matalic or ceramic what should i use.
October 15, 2012, 09:13 AM
use ceramic - they create less dust and the front wheels will thank you for it.
Question Answered: Alright my car was vibrating real when stop at a stop sign or stop light.

I have the same problem -- not sure what it is, but OK when driving, right? I thought it might be a bad idle air control valve, engine mounts or a vacuum leak in the upper intake manifold. I've had this problem for about 100,000 miles now. I just step on the gas at the sign or light with the brake depressed.
Question Answered: AC compressor engages and disengages at random, will not stay engaged or cool.
October 15, 2012, 09:02 AM
are you saying the clutch is engaging and disengaging at random? - Might be a non-oem clutch - Replace with a GM part to know for sure. I only say this because my Ford is now engaging and disengaging at random - only after being replaced with a non-oem part.
Question Answered: How many labor hours are necessary to change the spark plugs?
October 15, 2012, 08:33 AM
That seems like a fair price and a fair time - it took me the better part of 6 hours the first time I changed them - the front three are easy, but the rears are under the upper intake manifold. In the 2002, to take off the upper intake manifold you need to take out the air filter housing, rubber hose, battery (may need to be cleaned with baking soda and water), disconnect all the electrical connectors on the manifold, disconnect all the vacuum hoses, preferably take off, inspect and regasket the IAC valve, the EGR valve and the throttle body. When taking off the intake manifold you need to follow a pattern for removing the nuts, then regasket the intake manifold and put it all together to the torque specified in your manual for all removed parts. Easy, but time consuming. Also be sure to get a locking extension so the spark plug socket come out of the tube. Also buy and apply anti-seize to the threads and dielectric to the electrical connectors (the top of the plug and the coil.)
Question Answered: low on refrigerant
October 15, 2012, 08:22 AM
Get a kit with a gauge - it'll tell you how much refrigerant you need. They have good instructions on the bottle. I put in leak sealer and then later I read that after time the leak sealer breaks off inside the HVAC system and fouls it up. If I could do it over again I wouldn't have got the leak sealer. It should cost less than $40. If you take it to a shop - who knows, $250 - $600? It takes maybe 15 minutes in the parking lot of the store you buy the can at. DIY.
Question Answered: accelarator sticking in the mornings
October 15, 2012, 08:16 AM
I'd bet it's your throttle body plate - after a while the plate can get carbon build up and stick. You can take it off - it's connected to your uppper intake manifold (you'll need to replace the gasket) and torque back on to proper spec. They sell throttle body cleaner. Just spray it on and wipe the sludge off with a rag. It'll cost you $15 and less than one hour (if you don't have a torque wrench go to harbor freight they have good ones for cheap.)
Question Answered: Transmission filter change
October 15, 2012, 08:13 AM
Not sure if 06 and 02 are the same, but there is not an accessible filter to change in the '02. I change the transmission fluid myself and do it every 25-30,000 miles using the haynes/chilton technique. Essentially, flush, refill 1 quart at a time and run the shifter through its paces until full, then drain again, refill 1 quart at a time and run the shifter through its paces until full. It costs more, but it keeps the fluid pink and I have not had any transmission issues after 155,000 miles. I've read horror stories from people that take it to a shop and have the transmission fail within a week because they put in the wrong fluid or they didn't flush the transmission fluid enough to get it clean.
Question Answered: key stuck in ignition
October 15, 2012, 07:48 AM
Have a few other people try to get it out. For some reason, my wife can get it out and I can't. This has been a recurring issue for us - always when you least expect it.
Problem Reported: Ignition Misfires
May 22, 2011, 10:12 AM
<p>The common problem for ignition misfires are ignition coils going bad. Replacement of the bad ignition coil is&nbsp;necessary. These should be fixed as soon as a problem is detected. Otherwise the misfire can cause damage to other components.</p>
Problem Reported: Fuel Level Sensor Failure
September 15, 2010, 10:08 PM
<p>It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete <a id="ce_77" class="ct_glossary tooltip" href="/fuel-pump">fuel pump</a> module replaced on high mileage vehicles.</p>

<p>Illumination of the <a class="ct_auto care advice tooltip" href="/understanding-the-check-engine-light"><span class="ct_how_to tooltip">Check Engine Light</span></a> may be the result of a loose or worn gas cap.</p>
Problem Reported: Failure of EGR Differential Pressure Sensor
May 27, 2010, 11:09 AM
<p>The DPFE (differential pressure feedback EGR) sensor tends to fail. The DPFE sensor monitors function of the <a id="ce_8609" class="ct_glossary tooltip" href="/exhaust-gas-recirculation-valve">EGR valve</a> by measuring pressure changes in the <a class="ct_encyclopedia tooltip" href="/exhaust-gas-recirculation-system">exhaust gas recirculation <span class="ct_info tooltip">(EGR) system</span></a>. Symptoms of a failing DPFE sensor are hesitation or stumbling when driving along with illumination of the <a class="ct_auto care advice tooltip" href="/understanding-the-check-engine-light"><span class="ct_selected tooltip">Check Engine Light</span></a>.</p>
