Ive seen similar problems listed here but want to find out if anyone recognises this one!
Ive a 97 Z24 and it feels like it is misfiring/spluttering at 1500 to 2500 rpm, hesitates or coughs when i accelerate but is fine when im into the higher rev range Its really bad at idle when i put the AC on, it cant cope and nearly stalls. No codes have appeared and the MPG is high. can anyone help!
