Well this problem only started last week,

Noticed when i went over 5000 i didnt here the change over or feel any power increase, its like it stays on the lower cam shaft.

Ive read it could be a nimber of problems that cause it,

I havint hooked up the kpro to the ecu yet to see if there are any error codes,

It was doing it last night again,

Turned off the car and then back on and it came in then,

Could it be to do with the colder weather at all??

Seems to be fine when the car is drven for a while.

The car was driven for around 30 mins before hand??

Where is the vtec solenoid located on the k motor?

Would it be worth celaning or changing?

Thats what I was thinking as well. Oil level could have a big thing to do with it. Also speed sensor going out can do it as well happened to me before!! Best thing check the codes. The solenoid is on the left backhand side of the motor next to your header. Hope you figure it out!!!:up:

Oil is always fine,

It was changed last friday.

It was fine again today,

Is it a common thing for the solenoid to get dirty or need to be replace?

Nearly sure the engine is 04??

I might try using some 5w 40 or 0w 40 for the winter months its fairly cold out in the morning these days but i never rev the car high untill its fully warm, dont need to rev it high as its grand in all gears at low revs for daily driving.
