Thread: MAF question

The emoticons are actually the letter "B" ie 7 0 3 8 8 B

Hi folks for those interested: 70388B arrived from the UK the other day for the Princely sum of $114 aud. it works a charm. Idle issues resolved and fuel consumption back to standard land yacht versus Oil Tanker. Interestingly enough my hunting idle, that I put down to a malfunctioning stepper motor, is back to normal. I think (and this is purely based on my amateur mechanical logic) that the cactus MAF may have been sending erroneous high airflow readings to the ECU meaning the thing was just pouring fuel in a idle and running like a complete dog. I ended up going for the UK variant with the correct number of pins however I am curious to see if the US model with the extra pin would also work... May have to order one at some stage and find out ($90ish)

Hope this is useful to someone out there.

Just out of curiosity, I asked ALTO Land Rover at St Leonards the cost of an OEM replacement MAF for my 92. They had one in stock. $3250

Needless to say I walked out. Not even sure I gave the service guy an answer when he asked if I wanted it...

Can you post a link to where you got the sensor from.

Ditto......

There's some good info in this thread.

Is the MAF a simple R & R job or does it have to be "tuned in" to the engine?

There is just one adjustment on the maf and it's for the base co setting.
Correct procedure is to adjust this with a sniffer in the exhaust.

But generally you can check the outputs yourself and adjust the volts with unit plugged in and engine @ idle. Depending on engine specs anything between 1 and 1.5v is a viable setting. With the lower being leaner on fuel.

Assuming timing is correct, this adjustment setting should be done first, then check and adjust base idle, TPS.

There are numerous threads on AULRO and over the internet detailing the test and setting procedure. All that is required is a multimeter, an allen key or two (for maf and base idle adjustment) and a flat head screw driver (for TPS adjustment)!
