Are you SURE it's not leaking somewhere in the intake tract?

I've seen people post they had a slight leak between the supercharger and the intake manifold.

Mine is still doing it also. I have no engine codes or anything to help me narrow down what the issue is so I'm just driving around it

I may try swapping out the intake this weekend to see if that helps it...

Weather is warming up. With A/C on is even worst.

No luck. I swapped out the entire intake system upstream of the throttle body and it still does it.

I plan on removing the throttle body, cleaning the idle control valve, and checking all the mechanical bits in it next.

If that doesn't work... I'll have to try the pedal assembly

Do you mean all the parts starting from the head backward all the way to the throttle body?

Re toque all the bolts?

No, upstream of the throttle body which means (on my car) the rubber intake tube and the airbox primarily.

Hopefully I will have time on Friday to remove the throttle body and will report back as to what I find.

Mine resolved on it's own...

It started getting noticeably better and now appears to be just about 100% gone. I have no good explanation for this. The only thing that's changed is it's a lot hotter out now... maybe the warmer ambient temperature could be affecting the pedal assembly?

Assuming the problem is not resolved I have some advice: Chill out

Let the car adjust to the all the parts you've been throwing at it. It needs
a breather. Drive it frequently and go through lots of ready cycles (meaning engine on/off..on/off..)

He's been having issues for 4.5 years and your advice is to chill out? Insert face plant emoticon here.

I believe you mean facepalm

In all seriousness, I still think mine was due to something not being quite right in the ECU. The weird thing is it never settled down (even after over a thousand miles) with the stock airbox on. Now that I have an aftermarket one on there it seems to be running fine which means my stock airbox must have been leaking past the MAF (and I can't find any evidence of that)...

It's also been taught all over the internet that CABLE throttle bodies can be fixed, but hkfever's is by WIRE: which means electronic.

My issue still there. Damn

Can anyone advise how to tighten the bolts of the intake?

Lotus dealer can't help: - They tried lots of things
UK ran out of suggestion.
