hi im new to this site i own a green 1994 zx 16 valver everything is new and was running lovely parked it on the drive running 2 weeks later the car starts but will not idle at all jus stalls out replaced the o2 sensor,still the same,had 3 dionostics tests all come back clean with no fault local garage hasn't got a clue what could cause it any ideas would be very helpful,or the old girl may have to got to the car scrap heven lol thanks

Hey welcome... did you check the vacuum lead running from the airintake to the ECU? Those rubber hoses tend to harden out after 10 years or so and crack, so they'll leak. And what happens is -> it wont idle
