Hello

Recently I was on holiday for 2 weeks, during that time MIL turned on
2 times but after about an hour driving it was going off, on the way back
home the MIL turned on again so I decided to take the car (Honda Civic
2001 1.6 SE VTEC) to the nearest dealer to have that checked.

I left the car with them last tuesday 06-01-2009 and this afternoon
15-01-2009 they called me so I could get the car back as everything is
sorted now.

So I got invoice for 207.00 GBP with works done:

"With HDS found codes P0171 fuel metering too lean P0420 cat system
effciency below threshold checked no 4 10A fuse under dash OK. checked
fuel pressure OK (32- KPG at idle and 3000 RPM) checked oxygen sensor 1
with HDS found sensor opearation OK. applied vacuum to evap canister
purge valve"

"Intake side, vacuum held OK checked MAP sensor with HDS IGN on
atmospheric pressure indicated OK advice valve clearance check"

"checked/adjusted valve clearances, deleted codes road tested for approx
11 miles OK"

As I dont know much about cars I was happy to pay that price as long as I
had the problem behind but apparently I was wrong as after 2 miles I got
the MIL back ON, I was frustrated, I went straight back to the service and
they couldnt tell me anything, they wanted me to leave the car once again
with them but as I didnt want more expenses atm I said I need the car
over the weekend and they want me to bring the car at monday but I am
afraid they're just trying to get more money of from me.


Can anyone give me some advice or help please, any ideas or give me
direction where and how I could get ready myself for the next visit at the
dealer.

Thanks.

For the DTCs given, it looks like they did the right checks at looking for the main culprits for a lean condition - vacuum leak, incorrect MAP sensor output or low fuel pressure. Another thing to check is the injectors for proper operation. Also, you'll want to make sure that on their road check they ensure all the readiness codes get set before determining that the problem is no longer present (I would imagine they did however).

Another thing they should be looking at is the freeze frame data which may reveal the culprit for the lean condition by showing the sensor data at the time of the DTC being set. If the problem is easily reproducible, of course, it can be easily diagnosed without this data but with intermittent issues, the freeze frames can be invaluable in help determining the cause.

It sounds so right and it would be if not under rate of 90GBP+VAT/hr. I cannot afford another few hours of looking for solution and then getting car with what looks for me the same condition sad my wallet is not.

Thanks for help, I will try to find some cheaper solution.
