Slow performance up hills
I’m struggling with trying to find why I’m lacking power uphills , I’ve researched this forum and have looked at vacuum pipes to the fuel pump , I seem to have good pressure to the pump , I have cleaned the fuel banjo filter and replaced the fuel filter , I’ve had the turbo pipe off and seem to be getting good pressure from that too, though it did seem a bit smokey, but had no play in the shaft , I have flushed the gearbox oil too, cleaned the filter and the level is fine ,I do have what I believe to be the cold start switch, the unit is below the passenger seat but has been disconnected, the pipe that runs to the box section on the exhaust is disconnected, as is a vacuum pipe on the unit itself,, any other ideas or things to check would be much appreciated
Thanks in advance

Re: Slow performance up hills
The valve you mention in the exhaust check that it's open, if it's stuck partially closed or closed it would be like sticking a spud up your exhaust giving reduced acceleration etc.

Thanks for the reply, it there a way to check it the exhaust is open without physically taking it apart ?Northern Bongolow wrote: ↑Fri Apr 03, 2020 3:51 pm The valve you mention in the exhaust check that it's open, if it's stuck partially closed or closed it would be like sticking a spud up your exhaust giving reduced acceleration etc.

Just had a look and I hadn’t noticed before but the flap lifts up to reveal the mechanism, took a picture but can’t up load it even when I reduce its size

Re: Slow performance up hills
If it’s a 2.0ltr Petrol like mine, it hates hills and protests by dropping down the gears to increase noise whilst slowing forward performance. Hopefully you get yours to improve

Re: Slow performance up hills
If you manage to get an uninterrupted run-up all is ok, if you get someone dithering and then slowing before accelerating up the hill, the 2.0 is usually left struggling and clawing it's way up in a very sedate fashion. Used to it now, time to admire the views

Re: Slow performance up hills
Our 2.5l v6 is no better, so by way of warning I put a sticker on the back. I've wondered if the performance is usual but decided my other car and motorbike (neither of which even notice hills) give me false expectations. We just call the queue behind us, our 'fan club' as they follow us wherever we go. Is there an objective measure of hill climbing, I wonder? I've threatened to do a 0-60 test, but it would just take too long......

I’m based up in Scotland, so although the challenges are great the views are even betterFlanners wrote: ↑Sat Apr 04, 2020 8:10 am If you manage to get an uninterrupted run-up all is ok, if you get someone dithering and then slowing before accelerating up the hill, the 2.0 is usually left struggling and clawing it's way up in a very sedate fashion.

Re: Slow performance up hills
I did a very inaccurate one and had it someone around 13 seconds in my v6 which didn’t seem too bad. I have a diesel as well which seems better uphill but v6 is much quieter and gains speed in a much stealthier fashion
