2006 Audi A4 Quattro

Hi, I just recently purchased a 2006 Audi A4 Quattro 2.0T. I got it for very cheap since it does not start and I enjoy fixing cars at home. My diagnosis so far is either the starter motor or the relay for the starter motor. The battery is extremely dead so I had to hook up a booster pack to try and turn it over. When I turn the key I can hear the fuel pump engage and the motor cranking over super slowly??? I have a pretty good knowledge of cars and working on them but I cannot seem to figure out this one! Hopefully you can help me diagnose the problem so I can go ahead and fix it!

The battery may have an internal short. This could cause an issue with the booster pack. Install a known good battery and fully charge it before furthering your diagnostic testing.

VTC Oil Control Solenoid Valve Removal

  1. Disconnect the VTC oil control solenoid valve 2P connector (A).
  2. Remove the bolt (B) and the VTC oil control solenoid valve (C).
  3. Check the VTC oil control solenoid valve strainer for clogging. If the strainer is clogged, replace the VTC oil control solenoid valve.

Finally, note the amount of valve opening by observing the position of the piston shoulder (A) through the valve retard drain port. If you see the shoulder of the piston, the valve is open and must be replaced.

Chevy Suburban

My Suburban wasn’t starting so I changed the Distributor and Rotor.  It started but it runs at 4,000 RPM’s. I put a code scanner on it and got a P0102 code so I used Mass Air Flow Cleaner on it and tried again. Same thing, 4,000 RPM’s but no codes this time. Can you give me an answer because I’m stumped! I looked at the throttle spring and it seems to snap back OK, please help. It is a 1996 GMC Suburban 4×4 4 door Automatic with a 5.7 liter engine.

The engine running with a high idle is a classic description of a vacuum leak.

Chevy Code P0102

Mass Or Volume Air Flow A Circuit Low Input

Probable causes

  1. Sensor or solenoid faulty
  2. Connector terminal contact is damaged or corroded
  3. Wire harness – Check harness for correct voltage, open, short to ground or short to voltage
  4. Update control unit software – Check for the latest control unit update
  5. Powertrain or Engine Control Module faulty
  6. Battery voltage low

2002 Acura MDX

Hi, I have 2002 Acura MDX Touring and randomly when turning off the ignition, no power to anything. No power locks, radio or power windows. Key fob does not even work. Usually I have to wait 30 secs to a minute or more before suddenly all power comes back. Its like something cuts out and resets itself. Any ideas?

No power to anything

There is one thing in common with all the electronic components you mentioned. The battery. Not saying the battery is bad. However the connections may be loose or corroded. This is where I would start. This would also explain why you only have the issue once the engine is turned off. When the engine is running the alternator is able to supply power to those components.

LDV Maxus

my van starts and drives but going through the gears when you reach exactly 40mph it wont accelerate properly but if yu floor it in third and it reaches 52 it takes off like a rocket and no more problem till you drop below 52 and then its sluggish again

Wont accelerate properly

Hard to say what the issue is. If the check engine light is on you can scan the codes. The codes will help guide us toward the cause of the problem. You may want to try filling the tank at a different fuel station next trip. Could be contaminated fuel. Another possibility would be a misfire. If it has been a while since it was tuned up, you may want to start there.

2007 Ford Fiesta Zetec Diesel

The engine cuts out while driving. It has done this several times at speeds ranging from 30mph to 50mph. The car usually starts straight away but recently has taken several attempts to restart. A fault finding diagnostic has recorded no faults. What could be the problem?

  • Clogged fuel filter
  • Contaminated Fuel

I recommend trying a different fuel station on your next fill up. Continue to drive until fault code appears.
