You have a pm.

It’s grim isn’t it! I can see why people SORN them over winter but I’d be annoyed if a nice day appeared and I wasn’t able to take mine out for a run.

I’ve had mine out of the garage a couple of times because I needed the space to sort stuff out in there and took it for a short drive around the block to get it up to temp but didn’t go too far as I wanted to avoid getting the bottom caked in muck; definitely need to get some Lanoguard on there this year! Had to charge the battery beforehand because that had gone flat.

It’s back outside this week, currently getting soaked, hopefully it won’t snow and there’ll be a dry day soon so I can put it away again. It’s insurance renewal time coming up too so I need to give it a wash and take photos for the agreed value again. Fingers crossed the weather improves before the end of the month and we can get out there and give them a shine and a proper run…

Hi there

I am in a similar situation at the moment. After an ECU reset my 20VT ran pretty well, but over a period of about 2-4 weeks of driving, the performance under load/boost becomes sluggish. I don't know if you have actually checked for ECU errors but you're probably getting the same FRA error as I am (I think mine is now at -20.8), in that the short-term fuel trim has maxed out and the ECU has reached its max (lower) limit and cannot remove any more fuel from the mixture - i.e., it thinks she is running rich. However, when I check the live readings at idle for TRA (the long-term fuel trim parameter), it is sitting at +84, meaning the ECU over a longer period of time has been adding fuel to the mix thinking she is running lean.

My theory for this situation is that at idle (when my car runs OK), the mix is indeed running lean (I'll get to why in a minute) so the ECU begins to add fuel to the mixture (TRA). However, under load/acceleration/boost, however, the mixture begins to turn richer so the ECU's reaction to this (FRA) is to remove fuel bit by bit during each period under load/acceleration/boost. I have recently put in a new MAF and Lambda Sensor so I know that the intake and exhaust readings should be OK, and I am not getting any ECU errors pertaining to those sensors (whereas I was before - the SC/OC error).

I have not been able to locate it yet, but I think there must be an air leak somewhere in the system after the MAF. At idle, when the ECU thinks she is running lean, I am thinking that the air leak is a much higher percentage of the total air intake and therefore causes the ECU to experience a lean reading. However, during load/acceleration/boost, when the total volume of air that passes through the MAF is a much higher percentage than the air leaking in post-MAF, this creates the 'rich' reading so the ECU FRA starts to remove fuel again. An air leak post-MAF is the only scenario I can think of that would cause the ECU to think completely difference fuel mix scenarios.

My current issue is that I cannot find the source of the leak, nor verify that this indeed the issue.

Hope the above helps and interested to know if you made any progress resolving your issue?

Hi Morris,
I think you need something like this,
go hard buddy.

That's good value for a respray

And I can't work either of them !
