Long time since I added to this. EP3 is now on 206,300. Last MOT passed in September but with advisories which now have to be addressed or it's an automatic fail next time, so I understand according to the new rules.
Where do I want to go with it though? Before I spend money on new parts for the suspension and drivetrain, the most important thing to do is address the lack of power issue. I'll be straight here, it starts fine, it runs fine, it purrs nicely with no knocks, rattles or hisses you would associate with big-end, timing chain or vacuum system respectively. I can even drive it to work and back a couple of times a week without incident, and have been happy to do just that for the last three years. Longer trips than that....No Way!
When engine is cold acceleration is poor in all gears.
When engine is up to temperature:
Acceleration in 1st is sluggish - it really does struggle to get off the line.
Drive in 2nd is sluggish - not much power.
Drive in 3rd has much more about it.
Drive in 4th pulls nicely but runs out of puff around 5000rpm.
Drive in 5th good fun but runs out of puff around 5000rpm.
Drive is 6th is normally cruising on motorway at between 60-75 mph. That's when it hits a wall and won't go any faster.
Could the ageing clutch be the problem?
