hi guys, having a slight issue and I crnt pinpoint it, the car kind of judders more like bounces when I floor it at low revs, usually around 2-3rd gear going up hill, it's like it's struggling. if I'm above 3k revs it has no probs what so ever, and on good days it won't do it all.

it's a 1.8 SRi 52 plate, cars perfect in every way just every other day it has this problem, I blocked the egr valve off as I had an emissions light on the dash, that was 3 weeks ago and the light hasn't returned.

oh one other thing me temp dnt work pm the dash and heaters only blow Luke warm. if the car is stationary the temp works as should and the heaters burn hot like new, it's only when driving it stops working. any ideas?

thanks in advance

Danny

prob need a new stat same as mine did was running cold and fooling the ecu in to running richer . also worth trying new plugs

prob get some new plugs first a cheapest item 1.8 all seem to have stat problems if you do a search on here will be load of threads on 1.8 stats as you have blanked the egr off . were is the valve now .. have you made sure the valve can still work as in fixing it else were ' as it will still store a fault but wont put the light on

I have just done what most ppl do, it's still conected I just blocked it of with a blocking plate.

can the plunger on the egr valve still move freely... normally fit blanking plate and attach the egr to 1 bolt so it sits to the side so valve can still work but wont do any thing

Hmm not done it that way, I just blocked it off and put back on normal, so ur saying I need to block it off but have the egr to one side?how far to one side, like 90 degrees or just enough for the valve to move?

also as a thought, surly that valve moving up and down shouldn't cause a problem, cus all that does is allow air move through it when conected properly, so as it's blanked of any way it would just open for no reason...
