Lemon 0 Posted October 16, 2003 Hi I have a 1989 1.8 16v. When excelerating hard the engine seems to pick up well to start with then after about 4000 rpm, when the 16v engine normal pulls like a train it then seems to struggle getting to the red line!!! Very Strange. Had new fuel pump and filter, new lift pump, new distributor, rotor arm, new magnecor leads, new spark plugs. All the bits that may not help this sympton, but still no better. Anyone got any other ideas. Cheers. Quote Share this post Link to post Share on other sites

Lemon 0 Posted October 16, 2003 I did have my timing done not long ago, do you think it could be this? Quote Share this post Link to post Share on other sites
16VG60 1 Posted October 16, 2003 Have you checked the fuel system delivery and operating pressures. The fault is occuring when the engine is under higher loading. Your problem could be with the operation of the metering head and aiflow sensor. It could quite simply be a matter of the air and fuel supply being unable to match the demand under high load, due to wear or blockage. Would recommend you have the fuel /induction system checked for operation as replacement therapy gets a little expensive. Quote Share this post Link to post Share on other sites
Lemon 0 Posted October 17, 2003 I did not refit the new filter VW gave me on the lift pump as there where no clips as per the old filter to secure the base of the new filter? So refitted old filter as that comes with two clips. Any idea why they changed the filter. thanks for your help, not sure if that would cause a restriction???

Kevin Bacon 5 Posted October 17, 2003 Main pump sounds like it's dying. Had the same problem with an old 16v. Kec Quote Share this post Link to post Share on other sites
