Bit of info to help try understand the problem.
Car has been parked up since october 2014 so as you can imagine brakes may be seized. I have the car at a local garage having some welding done , they have changed the brake pipes and told me the disks and pads are fine just needs to be driven. They are working on the abs as light is on and tbe welding and should pass mot after this.
Now the problem, i drove this car around 300miles when i first bought it, so i expected it to be a little struggle on acceleration.However in 4th and 5th gear the car seemed to judder and lack speed even now it seems like the car wants and can do more but just struggles over 60mph.
Now the battery is weak so needs a new battery, there wasnt a overflow bottle which i have now bought. Just wanted to know if this is common or wer i stand with this. Could this be because of the battery or is this something else? I can see there is an after market ecu ,been told it has the 350z injectors. So could this just be the map has been set up incorrectly?
Any ideas on where to start?
