As the title says my vs ute 5L is missing at soon as the revs go over about 2500rpm whole car shudders. It also has an intermittant miss at idle. Has Code 36 couldn't find it for vs but vr section said vacuum leak. it has had this code for a while and the idle miss. But only recently has the shudders started. Its nothing to do with wheels or anything like that it is the motor. anyone have any ideas. could vacuum leak cause this
Also car has had new coil, plugs and leads
u have probbed bumped the map sensor hose off when replacing the plugs.. check the hose thats goes from front of inlet manifold thru it to the back then goes right to the firewall to a module there, if not, get start ya bastard, an spray it around vaccum hose areas and listen to the revs.
SIR LS1
the two ton go kart
Found the hose you speak of Dave, it had been rejoined and taped up don't know if thats my problem going to get new hose now. Also there are 2 hoses coming off the side the throttle body with vac written above them and going to wat seems to be a control valve. If I take these hoses off should there be some suction there, because theres not. If there shoul be suction wat could be causing it not to.
