I've read all the MAF and LAMBDA posts.....
and I'm not 100% convinced that I've seen my issue described verbatim which may be down to language and nothing more. My car is 1999 v6.
Engine develops a massive flat spot where there is nothing, nada, zilch, zero under my right foot sometimes when pulling away and especially changing up into second which is a bit scary when pulling out onto a roundabout or at a junction. Then it picks up again. This is the worst time for this to happen. It feels like no fuel is being delivered at all.
On the motorway typically at speeds under 70 mph the same thing happens where for a couple of seconds there is no pedal under my right foot and the car starts to slow. If you have ever run out of petrol whilst on the move then this is what it feels like. Then it picks up again.
This has been happening for a while and is steadily getting worse. There is no stalling. No warning lights on the dash.
Last night I disconnected the MAF and went for a spin but the same issue remained and again no warning lights. Based upon the posts I have read my next next step should be replace the Lambda sensor which I have ordered as the chap at the MOT station mentioned it might be on its way out and had the car on the emissions machine for quite some time before achieving pass results.
Before the MOT I had the front downpipe off and the current sensor removed from the exhaust but left on the car. I don't think it is anything I have done as the problem started before I started pulling it apart to replace the downpipe.
I have not tried a reset yet but will do so before the weekend.
So does this sound like the Lambda sensor?
I do love this car but it is ****ing me off recently not to mention costing me a fair few quid over the past couple of weeks and I have not spend the dough yet on the cambelt service.
Has anyone replaced the Lambda sensor on a pre multi sensor 156? Were you able to use the string method down the back of the engine to take the old connector down and bring the new one back up?
Have a good evening all.
