Guys
Looking for some advice
The car seems to have the following problems that relate to its running and I’d appreciate your thoughts.
I’ll show the results in the different situations:-
Idle in P - Lumpy, dips every few seconds and fire up again
D - Sounds like it's missing when pulling away, backfires then pulls no problem
Changing Gears in Auto - Backfire between changes if accelerating up or dropping down
Basically I really need to drive the car like a manual, when it drops down a gear for a corner for example and left in the drive position it will hesitate, backfire and then pull away.
A few things I’ve noticed, when its cold it runs quite well until I’m assuming the engine reaches the desired temperature - like an old choke, it then acts like that above.
In the last couple of weeks I’ve had the following replaced:-
Plugs / 2no Coils (no signs of abnormal wear to the previous plugs - improved running for about a week)
Complete exhaust Inc CAT (this weekend)
The only items I haven't replaced and I’m thinking of is the ignition leads and plug caps from the bottom of the coils.
The other thing I’ve noticed, it seems to have developed a metal knocking noise from the top front of the engine, could this be a tappet? It's more obvious at low revs and vanishes at higher revs.
The last thing I want to do is put it into a stealership, it’s covered 140k and had a valve replaced about 20k ago, MAS was replaced at the same time.
