I have a kia shuma 1.6, which has recently had a new lambda sensor fitted, due to the car missing, then the clutch was replaced (at 55,000 miles) the garage who did both of these repairs then disconnected the airflow sensor and said it would still run o.K. But needed a new one, however the car is still missing, and after a lot of hunting around for the sensor have found one, I have now put this one in, and there is no difference to the old one, ie, when you wire up the sensor the car starts but revs only just and out of time, but when disconnected car runs fine but misses now and again. Anyone any ideas, as this is getting costly and don, t know whether to take it back to garage for them to find something else wrong.

With everything installed, what are the trouble codes you are getting?
I would suggest getting a new garage. Any garage who disconnects the Air Flow and says it would work does not understand what he is talking about.

I have my own little diagnostics machine which is a memoscan obd-II u480 which has found 5 trouble codes, code p1610 (which is not in my handbook) p0100 (MAF or VAF A Circuit malfunction) p0110 (IAT Sensor Circuit Malfunction) P0130 (O2 Sensor Circuit Malfunction (bank 1 sensor 1) ) P0135 (O2 Sensor Heater Circuit Malfunction (bank 1 Sensor 1) ). I hope you can make sense of this and even maybe help with diagnosis, as am reluctant to take to garage unless I can find one that will actually help without stinging me all the time. Anyway thanks for the help so far, even if you can help no further at least you have opened up my eyes to this garage. Cheers

These 2 codes a re a fault with the front O2 sensor.
P0130 (O2 Sensor Circuit Malfunction (bank 1 sensor 1) )
P0135 (O2 Sensor Heater Circuit Malfunction (bank 1 Sensor 1)

All other codes are not listed in our database but your description should be correct, a fault with the MAF and IAT respectively.

P1610 should be MIL request circuit.

Clear all codes, run engine and recheck the codes.

Sorry to sound naiive, but I am not that mechanically clued up, how do I fix the problem? Do I need a new o2 sensor, and what does MIL request circuit mean? Can I fix the problem myself or do I need to take to another garage?

I need clarification of the present codes. Clear all codes and go for a test drive. Recheck the codes and let me know what they are.

MIL request is nothing to worry about. It is just for indicating that errors had been detected and engine computer is signalled to turn the MIL on.

I have taken the car for a test drive today after erasing the codes and it has come up with fault01 pend3 which reads similar to previous, p0100, p0135p, p0130p, p0110p, I assume that the p after the last three are pending, and bearing in mind that the airflow sensor meter is disconnected as the car will not run with this connected, also as I said previously the garage has put in a new lambda sensor, and I have put in a new airflow sensor meter (although this has made no difference to the original) any thoughts? Many thanks dave.

With the Mass Air Flow Sensor disconnected, you are not going to get anything done correctly.

The replacement MAF could be bad or of the wrong specification and I would suggest you get this resolved first.
