WV o2 sensor problem?
My WV has a check engine light on. So I told my car to an auto shop to fix it. They said it was caused by 02 sensor. So they replaced two o2 sensors -front and back (total costed me $600+). But after the replacement, my car’s engine is shaking now (it didn’t shake before) and the check engine light is flashed, then on again. I asked the auto shop, they said I should wait for 1-2 days. Is it normal? It seems like my car is worse than replacing them… Please give me some advise ASAP… thx….. Is this shaking caused by the new 02 sensor??
WV 2001 Jetta
I took it to a mechanic…. 
Yes, I think they screw up….
admin answers:
I had the O2 sensor changed in my car because it didn’t have power while climbing hills. The new sensor solved the problem immediately – I didn’t have to wait for the sensor to burn in. I would ask the shop to put the car on the diagnostic computer (no charge) and then see what the problem is. Shaking engine could be caused by a failed spark plug ($10 parts + 30 minutes labor) to a failed fuel injector ($200 parts + 2 hours labor).

Does my car have low compression?
My VW Beetle 99 with 2.0L engine has the following problems:
1.) oil burning (half QT when driving 1500 miles)
2.) sometimes lose power before shifting gear from 2-3 (not always, maybe occur 1 every 10-15 times)
I am thinking ita piston ring is worn so sometimes it burns oil. that’s why it sometimes lose power due to low compression. However, when I am driving at a constant speed, it does not lose power
My auto transmission is NEW (4000miles since replacement) so it must not be tranny problem
What do you guys think?
If the piston ring is worn, how much does it cost to go to firestone or dealer to have it fixed. (parts + labor)
Can I just leave the piston ring alone?
I keep driving and it has no any other problems except lose power
admin answers:
The transmission must not be the problem but it most certainly could be the problem.
Loss of Power at Low Speeds
One of the primary symptoms of a faulty torque converter a struggling of the torque converter to adequately distribute power and maintain shift for the automatic transition. Alternatively if the stator is free-wheeling in both directions and not pushing the fluid in any direction from the turbine, it will cause the vehicle to experience acceleration problems at lower speeds because of the lowered torque. Performance and acceleration would be poor at lower speeds, however the vehicle would perform normally at highway speeds.
Engines do not lose power just as the transmission is shifting from 2-3 gear. That’s too confined for the engine. There are two possibilities, the transmission or the torque converter. The torque converter is most likely the cause of the problem.
Low compression also cannot cause loss of power only at a certain rpm or engine speed. Worn piston rings will cause loss of power no matter what the rpms or engine load.
The oil leak is most likely a seal that is worn. Since the transmission was replaced, I would look at the rear main seal that was disturbed recently.
Betty asks…
Should I remove my car’s spark plugs just to reduce the gap by 0.004″?
I have a 1999 Ford Escort ZX2 with a 2.0 L DOHC Zetex engine, only 45k miles and like new. I replaced the plugs and gapped them according to what the Auto Zone salesman told me, 0.054″. Later I discovered that he gave me the gap for the wrong engine, and that mine should be 0.050″.
If I fix this problem, I’m gonna start over from scratch and buy new plugs because it’s not worth the effort of removing the thread and insulator pastes. (Opening the gap would be easy without doing that, but tightening the gap would not… hard to get a grip with all that paste there.)
Will that extra 0.004 in the gap really make a difference, and justify my time and cost to correct the mistake?
(BTW, the replacement plugs I used are Autolite Platinum and cost something like $2.80 each. If I buy a new set, I want to make sure I have some good long-lasting ones. Should I use Motorcraft Platinum instead, which is what the originals were? Will the extra cost be worth it? I think they cost about $6.00 each.)
admin answers:
Well, here’s how I look at it. Run the car and see how it does, if it’s okay leave it alone. 4/1000th’s of an inch is minuscule. If it does start running a little different sometime down the road, take the plugs out and re-gap them. Keep in mind that gap is going to get bigger as the plugs wear.
As far as the plug brands, I have to say, I’ve never had a problem with Autolites.

1957 Pontiac Star-Chief Restoration.?
Please, experienced intelligent answers only.
I am contemplating the purchase and restoration of a 57 Starchief.
The vehicle is in fair shape, I rate it as 5.5 to 6 of ten points on the scale. The body has a little visible rust, nothing deep, no holes and No dents anywhere; the chrome is 90% good to go and is sweet, with one exception on the left rear bumper. The intererior is ok, the upolstery needs replacement and window seals also; the paint is to be replaced and I intend on painting over a Lime green exterior and intererior with a Cream off white over Rootbeer brown.
It runs, has no obviouse engine issues, needs to be cleaned and painted under the hood and some chrome added where applicable.
The issue is I am not highly experienced in any automotive field; yet, I can do some work and I do have friends whom have high experience in all restoration areas, mechanics, auto-body-paint-wiring and so on.
I would like an assesment on what one is getting into in time-cost?
admin answers:
It all depends on ones definition of restoration.. To some it’s just a cheap paint job for under $1000 and to a professional it’s a frame off costing tens of thousands and then there are many points in between.
So for any sort of restoration it’s going to cost lots of time and money. It is nice to have friends..

C they deflate and return to their original positions after a collision, eliminating the need for replacement and additional repair costs
D they have a “dual bladder” design to cover more surface area and better protect the occupants head and chest
5 which statement is correct regarding all speed traction control?
A when the traction control system is activated at speeds of 35 mph or higher, the braking system is deactivated and only engine control is used to limit wheel spin
B when the traction control switch is activated, a mechanical lock inside the rear differential housing solidly locks the rear axle shafts together
C the system uses a viscous coupling to mechanically link the drive wheels together for improved performance on slippery surfaces
D the system uses torque converter to increase torque to each wheel when wheel slip is detected
6 how long does the SOS post crash alert system operate?
A until the airbags are completely deflated
B for up to 20 min and then it shuts off
C until it is deactivated or until the battery power is depleted
D until the drivers door is open
7 what feature built into the infrastructure of all ford vehicles helps dissipate the force of the impact?
