Vr6 caddy Posted November 24, 2018 Share Posted November 24, 2018 Hi and hope help is near... I have a caddy with a vr6 conversation AAA code( don't know much else) It has a real lack of low down throttle response and runs very lumpy until it hits 2.5/3 rpm then takes off like a vr6 should.. I have replaced ht leads and plugs to start looking for a few other maybe's...... Coil? Maf? Coolant sensor? 1 1 Quote Link to comment Share on other sites More sharing options...
Volkswagen Owners Club Posted November 26, 2018 Share Posted November 26, 2018 Hi....welcome to the Forum The fact that it is 'on song' at higher revs suggests that it is something like a vacuum/air leak in the in the inlet manifold or associated trunking which is causing the lumpy running. A quick emissions test (Oxygen levels) which if higher than zero suggests thats the fault. Let us know how you get on with it Cheers, Trevor 1 1 2 Quote Link to comment Share on other sites More sharing options...
