270 for 4 spark plugs

Well had the car in the dealers again yesterday.

For those that don't remember, electronic fault light, was told Cat and Throttle Body , did the Cat no change, replaced the Throttle Body , no change...............

Well yesterday they traced all the injection system wiring and equipment and just as they thought nothing was untoward the guy noticed the resistance readings from the spark plugs.

Turns out, as discussed on the forum elsewhere, that the plugs used by the garage I bought it from in the service were not Renault plugs. Basically it appears the resistance was building up so high it would "crash" the electronic system causing the problem. Although the computer showed throttle body it did actually pinpoint it as "unidentified".

Well they want me to try it for a couple of weeks and see but looks like I spent 270 on a new throttle body when i needed 4 new spark plugs! EXPENSIVE PLUGS EH
