Loss of Power
Loss of Power
Any Ideas?
When I am in fourth and fifth gear I seem to have a loss of power at 4.5k revs, they seem to die off then it it pulls again, like a blip in power momentarily!
I have had two suggestions
1 - the engine doesn't like the K&N Typhoon I have fitted.
2 - the spark plugs.
Anyone else any thoughts or knowledge
Cheers

As Aido suggests, it would be worth taking off the induction kit and seeing if the problem goes away.

Not sure when the spark plugs were last done it does have full Lexus histoy to date and it's now on 97k!?!
It does have a MAF sensor maybe have that looked at.
Think I'll try the old air box back on it first as I can't remember if it did it when I had original one on and let you know, only thing air box is in Portsmouth at mo :tongue_smilie: (have to wait a couple of weeks)

I don't think it's a misfire, it makes the noise of loss of power like a surge if that makes sense, as it's revving nicely then drops?
It is an auto, however I know what gears it's in as using it on the padddle shifts in manual mode!
