yeah mate sorry i did mean the coil pack itself aswell. Your'e right about darts parts too many garages these days are ripping the utter hole out of it, and its because their workshops are full of young boys who believe the diagnostic tool is gospel. I'll keep you updated with the results. cheers.

I actually have a compression tester kit bud. Going to do that tomorrow while waiting on new leads and plugs. Thanks so much for your advice. I will keep you informed of future results bud, and pick your brain again if i don't find any further faults. cheers.

I get what you're saying bud. As i removed the plugs and they where very old for 1, and most of them were wet and it was pure fuel. I did put an old plug into each lead and they did fire against the cross frame, but correct me if i am wrong here. If the plug doesn't spark in the cylinder as the the injector sprays, then this would obviously explain why the plugs are wet. Is it possible the plug isn't sparking at the exact time it should? so much as to cause the car to drive like crap under load, but the engine idles fine because the spark timing isn't too far away? Which would suggest a coil fault but not severe enough to throw a fault code? please excuse me if that sounds a bit thick lol. I'm just trying to find an obvious solution as i have pretty much eradicated the more technical faults like the timing. cheers bud.

Thanks for the reply Bigdev. the car does drive all be it very slowly. the lack of power is stopping the accelerating as it should whilst driving. when the auto box is shifting up the gears during acceleration and i lean a bit lead footed on the pedal the revs go up to around 3 thousand revs and the rev counter just bobs there and the gear doesn't shift. so when i back of the throttle let the rev counter drop to around 2 thousand and press the throttle pedal gently it shifts up gear but the power still lags severely. if i press the throttle pedal harder after this the gears shift down unnecessarily and the rev counter again bobs at around 3 thousand until i do what i just described again. during acceleration it takes an eternity to gain any speed. Getting to even 40 mph feels like a lifetime to get there. thanks again for your reply mate.

Hi. i have a grand voyager 2005 3.3 v6 petrol automatic. when i select drive and try to accelerate there is a serious lack of power. the engine idles perfectly, but takes forever to pick up any pace, and when i get above 40 (eventually) there is no gumption to want to go much faster. it takes an eternity to get up to 60. the gears don't change as they should. the revs get to 3 and a half thousand, and the rev counter begins to bounce and will not change up gear until you let the throttle off it drops to around 2 thousand, will change up, but if i press too hard on the throttle it will down shift shoot up to the 3 thousand mark and the rev counter bobs. Now i have changed spark plugs, cam sensor and crank sensor as per diagnostics, to no end. I've had it checked with the star scan tool and found the timing was out, therefor i had the timing done also. whilst it was in getting the timing done the mechanic noticed that the manifold was a cherry red color and suggested that the engine wasn't breathing properly. once the timing was done i removed the exhaust system to check the cat and other pipes for any obstructions or blockage. Again i hit a wall and found hee haw. i am at a complete loss as to where to go next, because regardless of any parts being serviced the car still will not accelerate as it should. Can anyone help?? Has anyone had this problem?? Is there something i'm over looking far simpler? I may well be looking too deep. Any help or advice would be greatly appreciated. Thanks in advance.
