The car has recently gone in to 'limp home' mode a couple of times especially when I put my foot on the gas. It was suggested I remove the EGR valve and give it a thorough clean, including the operating lever. Looked easy, a couple of bolts to remove, then wiggle it out. 2 days later and after numerous attempts ... with lots of 'expletives' and grazed knuckles the EGR valve is still in situ. I can just about rotate it back and forward about 30 degrees but that requires lots of turning force, including levering and hammering on the flanges (near the bolt holes) which is taking its toll on the bolt holes and alloy body. Have tried revving engine a few times to 3,000 revs and 'blowing it out' as shown on a YouTube video ... didn't even budge 1mm ... or even a hundreth of a millimetre! To prevent any damage to the valve, I even considered unbolting the motor bit from the valve so I can get a better purchase on the valve section in the hope I could generate more leverage and turn it further but can only get at 3 of the 4 bolts, due to operating lever being in the way. Any ideas on where I can go from here? It really is 'stuck tight' and rotating it the little I can, seems to make it tighter ... not looser. I would add that I am reasonably competent with the spanners so it's not a case of being a complete plonker, it is just being held in there 'tight'! At the moment its, EGR 1 v James 0.
