I hope you lot may be able to help me?

 

My battery went flat and I boosted it of my mates jump pack.

I let her run til warm then set off. I woudn't rev over 2500 rpm .Its an Auto box,import so tried all the 'box modes but none of them changed the rpm limit.

Took her for about a 3 mile drive but still the same.

I have to point out that when I moved it last night, when I switched it off it kind of , felt like back pressure or something as the engine lurched , I guess thats the best way to explain it.

 

It starts fine,and runs up to 2500rpm as normal, is it a problem with the air mass meter? and where is it on these :censored:cars?

Don't know what the problem is mate but the afm is under the centre panel (well just above but you get the idea).

Clean the connectors on both the MAF, and the harness. Also the element inside the maf(looks like a thin bit of wire) may be damp or dirty.

Clean spade connectors with small file so they are back to copper, then spray with contact cleaner like ambersol.

Clean maf element with contact cleaner or some carb / injector cleaner.

 

Might be worth doing an ecu check to see if it throws up any faults.

Thanks Guys, thats helped me out, went to start her up this morning, and the battery is FOOKED!

 

I will have to sort it out later, too many things goin' wrong at the mo, Windows Vista is screw (I'm in safe mode) the fan oven element has just gone BANG. My Octavia has an ABS wheel sensor gone down as well as a tempermental heating fan!, The Z is fooked and I have Flat pack furniture to put together that my wife won't stop nagging for me to get done!

 

:clover:

 

And they say the Irish are Lucky??? pfft!

 

:duffer:

 

Thanks again, I let you know how I get on, better go sort some this shite out!

Hey, back now!

 

Still no change, cleaned every connection related to the MAF and the injection system, took her for a drive, still limited to 2500rpm AND 80kph!!! in Hold mode!?

Might be thinking the ECU is holding back on something else?

Condition of the pins on the MAF where fine, and the element too, so now I'm confused.com???

 

Its starting to look like the most reliable car I've owned was a Delorean!

 

everything works well, up to 2500rpm then there is a clunking from prop/diff when trying to go past 80kp/h? that pulls the car back?

 

Wierd!

 

Better get on with the flat pack furniture, but at least I fixed the Skodas' little niggles!

 

(waiting for my mates hooky copy of 7 too ; ) )

The afm when failed gives a 2.5k rev limit as mentioned by others, also this occurs if it is disconnected or has a broken cable in the loom, a continuity check back to the ecu will confirm the cabling good or bad.

 

However low voltage will also cause the same and you mentioned having repeated flat battery you need to check the alternator is charging with a test meter, it may even be a dead battery causing electrical issues.

 

Of course it could just be a complete coincidence and the afm had died so you may wll just have to replace it.

 

Good luck

This morning, I thought I'd start her up as the flat battery was due to shitty contacts with the terminals, so battery is charged and fine. once she started a blipped the throttle and she went up to 3500-4000 rpm then never went beyond 2500 again, day off tomorrow so will take a look at the MAF again.

 

Thanks again guys, muchos appriecito

yep the maf will need replacing. the one on my car looked brand spanking new and still went wrong. the one i fitted afterwards looked much worse for wear but works perfectly. so dont go on what it looks like.

Just taken the MAF out, and going to have a peek tonight, the wiring looks fine all the way to the ECU.

 

If anyone around London area has a second hand one that works and wants to sell it let me know.:blink:
