Hi guys,
Still having problems with my lumpy idle and i'm also noticing a problem with the engine suffering a loss of power.
To better describe, idling from cold the engine seems a to judder occasionally that can be felt inside the car. No problems while revving the engine and as it gets up to temperature the idle slowly drops accordingly to right around the 900rpm mark.
While driving around slowly in second the car sometimes seems to pulse or surge, as if i were moving my foot up and down slightly on the throttle. On the motorway or dual carriageway when getting up to speed the car can sometimes feel starved of power, like it takes way too long to get up to 70mph and foot to the floor throughout the gear range still has VERY gradual acceleration. Driving up to 4000rpm between shifts seems to make it seem more lively but i used to change gears ataround 3000rpm 6 months ago. Once at 70mph if i lay off the throttle it seems nice and steady but if i were to try and drop to 65 then go back up to 70mph foot to the floor wouldn't get it there.
After getting frustrated with it on the way home yesterday i tried stomping on the peddle a few times at around 65mph and after a couple of presses (and thoroughly bouncing the girlfriend around) the car came to life and raced up to the 80mph mark with little to no problem at all. After 600yards it was the same, starved of power and needed the peddle cycling to get the acceleration back.
Now i've had a google and some people said it could be the spark plugs. So with the engine running i removed the HT leads from the spakr plugs one by one, but they all made an impact to the engine sound when removed so it looks like they're probably working okay.
I've just now seen a couple of threads on here from a few years back and the guy replaced his lambda sensor which cured the jerky driving and power issues. Would it be a good course of action to jump straight into replacing the lambda sensor with one of these and see if it fixes it or is there a way to test the current one first before shelling out £50 on a tiny little sensor? Also, neither state whether they replaced the front or rear lambda or even both, as far as i understand the freebie has 2...
Any help muchly appreciated and i apologise if this seems like a stupid question. I didn't know which piece of forum etiquette to break, ask a simple question or bump a 4 year old thread.
