Hi got a corsa 8v r reg normally have no problem with it but now its started to slow at pulling away
put my foot down and it is so slowwwww and seems to be running on 3 cylinders and sluggish when
changing through the gears and has a smell of petrol from exhaust pipe i checked the plugs they are
ok but it idles rough checked expansion tank that is ok no smell in it though there is some Mayo on
the oil cap I changed the water pump a few weeks ago the oil cap was clear until now could anyone
give me any clues as to what could be happening please????

mayo indicates head gasket faiure, is there a new ticking sound when you rev? thid would indicate the head gasket is blown in one area possibly between pistons other than that i not quite sure.

1997 r reg 1.2 8v corsa when idling it seems to only firing on 3 cylinders it starts ok no problem but when setting off it is sluggish
acceleration is bad when changing through gears I checked plugs , leads ,fuel filter, clean air filter could anyone help please

dont think mayo is HG on 8v's its very common, i had mayo for 4years's and ran sweat as a nut no problem's

right buy the sounds its either over fueling or or has a bent valve,

had cambelt recently? if yes it timed right?
temp sensor working? only way to check it change it
lambda ok? prob throw eml if ticking over or at stead speed and go off after
crank sensor? should throw eml tho
coil pack? or dizzy depending what its running
hope one fixes it wont cost much on a 8v

Had this on my C14SE, throttle position sensor. Official Opel mod is to remove the three way connector in the TPS cable (not the one IN the TPS) and solder them instead.
