Title: losing power
Post by: marcogolfo on 03 July 2005, 11:09
hmmm this is quite funny really but not if you get my drift.  I'm driving along and after 40 miles the car just decides it doesnt wanna go above 50 regardless of how hard you push it, like somethings restricting it, so im driving down the motorway thinking where the hell is the next services i really need to stop.  What a nightmare i thought i was low on oil and the engine was seizing.  Well after 20 miles of going slow on the m6 i get bored and start to play about with stuff,  i find that when you push the electric window switch the car picks up power again and as soon as you let it go it dies.  Lol funny as f**k like i got a turbo button or summat. :grin:  It has been alright since and only seems to happen on long journeys i.e. 50 miles
just thought id mention it tho and see if anyone had any ideas

does the engin rev freely when at a standstill? if it seems like its miss-firing it maybe something simple like a bad lead or plug or the mass airflow meter, or if its burning oil do a compression test to prove the rings, if the engine is ok check the clutch, if all that is ok you may have a high resistance earth prob or a major loom prob, hope this helps

thx i think it was just a dodgy lead because it hasnt done it for a while however it does seem to feel like its misfiring when its cold and it has trouble starting when cold in  winter although since its been warm weather its started first  pull. Thx for your reply its very informative.  Where is the airflow meter at?  A mate mentioned  this could b the problem as well

Mate, try disconnecting the warm up regulator connector, it cured my prob, and you had a similar one!
If it does then you know what's kanacered!

ooops, sorry mate, just saw this thread!

The WUR is on the right of the block below the temp senders! it's a creamish/white connector plug and there is a plastic cap next to it!

hmmmm its started doing it again after about 80 miles i start running on three cylinders intermittently.  Its a nightmare, i tried disconnecting the WUR and it made no difference :embarassed:

Sorry mate! - it may still be the WUR, disconnecting the eletrical bit just stops it heating the coil inside, it still has to function.  I just got one off ebay for a tenner! i'll let you know!

Also try changing all the earth straps! it's cheap to do, could be a bad earth!

I did mine recently, easy job!

in regards to the starting problems you haven't put a performance filter on your car have you? as i put a race k&n on a car of mine and it made starting and running the car in the cold a mare mate. in regards to the power prob take your car to a local garage that has a sun tuner the machine will tell the mechanic what is wrong with the engine and from the readout he should be able to diagnoise the problem,  it should only cost you between £25- £40, failing this a rolling road specialist, hope this helps

For a cheap first option, pop down to your local MOT garage and ask them to set the C0 for you - If they are quiet should cost about a tenner i guess - here is what you set it to -


Disconnect the red lead by the coil, start her up, and adjust the idle from the idle screw to - 1000 rpm, then set the C0 to - 2.0%, then switch engine off, re-connect red lead, then re-set the idle speed to around 950+

At least this way you know the mixture is set up correctly!
