Question
Help me??? Jumped in my 89 2.6 petrol isuzu trooper, started OK but Petrol and Battery lights stayed on (plenty of petrol!!), heater/blower stopped working along with the rear windscreen heater. Once the engine is warm it idles at about 2300 rpm, whilst driving feels like it has a "flatspot". overun when i turned it off???!!!

Answer
I would start by having your charging and starting system checked Andy. Alot of problems can come from a bad voltage regulator. Also for the idling problem that is most likely bad intake gaskets/ vacuum lines and or a bad TPS. I would chekc your fuses and relays to see if any are blown which would indicate a short in your system as well. Let me know what you think:)
