A while ago I put up a thread about my car and its "Lumpy Running" well, today I travelled to Dagenham to have my custom exhaust fitted, and its a really nice job, however I was really dissapointed to find out that the car still drives really badly. For those who didnt see the post before, it basically stutters and doesnt seem to have much power (except on the motorway where it will happily pull over 100mph).
Basically, the engine struggles - I thought it was down to the cat being blocked, but now with the new system it is barely any better.
Cemesis kindly popped round, and we tried different leads, but to no affect. The plugs are new, and there is some sandy brown deposits which indicates fueling is fine.
We ran the car without the air filter - still bad.
The engine has only just gone in, so oil is new as is the filter, also it has recently had a new fuel filter and damper.
I tested the fuel pump recently.
SFI box is on tightly.
The first thing we did was reset the ECU and then drive the car. It ran well for about 10 seconds until I pulled out of my road and onto the main road and then started running badly again, - could this be that the ECU is learning incorrectly once I started driving it?
We reset it twice (30 mins, the an hour) and both times it drove fine until I pulled out onto the main road then it went back to its hesitation and bad running
Does anyone have any ideas, as I am out of ideas and pretty depressed about it
PS: I then discovered the sump was cracked, so I now have 2 problems, this car is cursed.
