Hi All - anyone know why this is happening, just started the car up after about a week with no use, as the engine started the choke seemed quite high, at about 1,800 revs, then I assume went off, as the car approached midway on the temp gauge, it started to blip from 1,000rpm to 1,100rpm, sounded like someone was blippng the throttle - any ideas ???

 

Well just been out gave her a bit of a run and blow the cobwebs out so to speak - tried in full Auto mode and Sport Shift -/+, now seems fine

 

Keep an eye on the MAF. It "hunts" when it's starting to go.

 

Thanks for the heads up - it's the 2nd hand one I bought from Dave Coe - would it be erratic in its "blip" ? this was very regular....

 

It normally "hunts" between 500 and 1400 rpm. It's a regular surge and decline in rev's. If this is what you mean by regular then it could be the problem.

Try reseting the ECU as you have just changed it and see where it goes.

A quick test is to disconnect the MAF while the engine is running, if it still runs it's 99.9% fooked! The ECU as learnt to run without the MAF. If it dies like John Wayne then

Sorry but I hope this helps.

 

Yeah big help thanks - I have never reset an ECU before can you give me a pointer on how to do it ? - it was regular, every other second it seemed to be revving on it's own

 

i think ians right sounds like maff to me.

 

It could be the maf or the idle control valve

 

Cheers Guys - thanks for the pointers - where is the idle control valve situated - can you see it on the engine ?? or is it buried away ?

 

Well I unplugged the maf connector - car nearly spluttered and died, but then revs increased and continued running with maf dis-connected, re-connected dipped and spluttered again, before idling again, but not idling too badly at the moment ??? not driven it for a min, but will to see how it behaves in traffic...............................

 

Sounds like the MAF. The ECU was compensating for the MAF and continued to tell the engine to run. Not sure on the Newage but disconnecting the battery for about 20 mins to re-set the ECU seems to ring a bell.

 

yep disconnect the battery, cable tie the battery terminal wires together and leave for 20mins on a classic..... having similar problems of my own so might try the whole unplug thing tooo.......

 

thanks Guys - so glad SN's here to help !!!!

 

Oh P.S....is the car OK to drive with stuffed Maf ............

 

The Maff has left the building and should be with you by tomoz "I Hope"

I hope this sorts your problem buddy!

 

Nice one I got it all crossed - thanks again

 

Hi Peeps - Well just spent a week in Hospital and finally got round to fitting the "new" Maf - ran well initially, though revs on choke were higher than "normal" but on reaching half temp 9on the gauge) the car started "blipping" again check engine light also comes on, but I have yet to "road test" the car - to see if it settles.

I have disconected the replacement Maf and the car dies on start up still blips the only thing I have done to the car is fit a Boost gauge (stepper type) "T"d off at the Dump Valve Vacuum hose, which I can feel a vacuum "suckin" on the end of my finger, which I assume is what should be happening, Should the car have been re-set in some way after I fitted the "new" Maf sensor ?? is this why it is behaving in the same way

 

watching this with interest got the same problem with mine...... does your check engine light clear if you blip the throttle slightly out of interest?

 

Hi No the light stays on - I tried slightly revving with the "blips" but it didn't do much, my hopes were pinned on the Maf, but have been told it may be the idle control valve - just hopimg for a definitive answer to the problem, hoping it's not going to be one problem with a load of maybe's !let me know how you get on if you can

 

did u reset the ecu after putting the new maf on if u didnt try thatmight help!

 

Hi I didn't reset the ECU, as I didn't know what the best thing to do, would be - I read on here "somwhere" that a New Age ECU had to be reset via a Computer, as opposed to the classics which you could manually do

I have just been out in it and although performance seems OK it's idling crap and when coming to lights etc, wants to over idle to around 2k-2.5k revs !! it's like it wants to accelerate itself, bit like herbie flippin annoying The CEL wasn't on initially but soon came on again after the run................

 

Try posting in the technical section, you might have a bit more luck.

 

Thanks Ty, I will post it there too - very nice brakes by the way !!! Your cars going from strength to strength

 

Sorry to be boring !! but just thought I'd report on the this issue which seems to have resolved on it's own - after the initial problem started a short 8-10 mile run saw it idle all over the place, just before turning it off idling at 2.5k !!!! anyway 2 subsequent short runs in the car have been great, idles now at a steady 800 !! So can only guesstimate that the car's ECU has "re-learnt" some settings and settled itself ????????????????? if that's what is does..........
