i hope some one can help with this as its been a problem ive had with the car ever since ive had it

the engine is a D15Z6

basically, usually from cold, the engine will start really well with just s touch of the key, it will warm up fine with vtec a the "econo" light working as it should

but then say if im croozing at 70mph with the eco light on it will miss fire the eco light will go out and vtec wont engage either :S

even worse some times the car wont want to start as well, like taking a few turns so start then it will warm up ill get no eco light and vtec wont engage and the car will feel slugish

i really dont know whats going on ? ive chahged vairious sensors, earth straps and the oil level is fine :S

hope you can help

cheers
