Hi everyone,

My kitty and I had this wonderfull drive the other day, when suddenly she died on me. I couldnt get her alive at that moment causing a heavy traffic on a public road. Some time later she would fire up but when getting warm the engine would stutter and have huge hickups in the high rev range, undriveable this way.

I dont have an OBD2 scanner ( I really should get one of those) After some research i checked various sensors with my voltage meter, everything seemed to be fine.

After a reading alot of posts on the forum from other members i came to the conclusion that i could try unplugging my MAF sensor.
I read in other posts about clogged cats, but i didnt believed that happening to my car.

With unplugged MAF, the car was driving okay'ish. A few hickups in the lower powerband. But overal enormous improvement.

I cleaned the maf with a special cleaner this had no result.
When you unplug your MAF, the ECU takes a standard profile. I think it even discards the reading of the O2 sensor, but im not totally sure on that. Maybe someone else could clarify that for me.


I had 2 possibilities since the car was running alot better with the unplugged MAF.

Symptoms: rough idle, severe hickups in high rev range with defect MAF plugged in. little hickups and powerloss in low rev range with the MAF unplugged. Still running poorly but huge difference when its plugged in.

1. defect MAF sensor
2. defect O2 sensor

I went to my local scrapyard nearby and to my surprise there was a 96 X300 VDP on top of some Renaults. I picked up the MAF sensor from it, plugged it into my car and behold! The car is running excellent again. Yay!

Excellent throttle response, no hickups. purring like a happy kitty.
The MAF i picked up was an absolute dog, white dots and stripes over it not rly nice but hey it works and i payed 50 Euros for it, so i guess im a happy man!

PS: The part number on the replaced MAF is totally different then my old one. Im not sure if they are all the same and work on all models

 

A Denso 197-6030 from Amazon works fine $58, Made in Vietnam!! Comes in a Denso box...For Wife's 2000 XK8 !

Cheers, Adrian

 

Not 100% sure why it worked because I am pretty sure it needs to be the same part number as what you had in there previously.

 

The Lucas brand Jaguar part # LHE 1620 AA is the correct official MAF for your normally aspirated AJ16 engine.

The supercharged version is # LHA 1620 AA so the numbers are close

Not sure on your post if your vehicle removed MAF is in the picture
