mjltigger · Jul 31, 2009

are any of the V8 experts free some time very soon to come and help me diagnose my car..

was running brilliantly since I did the last few jobs after the head change until couple days ago when it seemed to have lost a little power and the tick over had dropped again..

now it stalls on overrun nearly every time, especially when cold, drives like a dog and has no power whatsoever..

runs the same on LPG or petrol and on a long drive yesterday wouldn't do over 70mph..

so HELLLLLP!!!!

Check vac advance is working.

Check the MAF sensor and Lambdas if you have them. Having one Lambda out on our V8 makes a right mess of the carburetion, even on gas.

disconnecting the MAF while the engine is running makes it stall but there doesn't seem to be any difference in running with it on or off so will try the old one.. the lambda sensors are the ones on the exhaust yes?

Yes, they should have orange connectors, both on the loom and on the sensor.

We have a 'dead' one and looking at the engine management system on gas (Zavoli multipoint) you can see the Lambda readings going haywire on Bank 2, and the same on the diagnostic reader which confirms our suspicions.

We have the reader for the diagnostic socket on the vehicle and the diagnostic socket on the gas ECU.
