Renault Repair Questions and Answers

Question: 1987 Renault 25 GTS  mileage: 75,000. My car has been off the road for about 4 months. During the recent fuel crisis in the U.K., I put 4 gallons of 4 star petrol in as a stand by in case the family car ran out of petrol. I decided to put the Renault back on the road and after recharging the battery the car started and appeared to run sweet enough. However after about a quarter of a mile the engine began to four stroke, (dull heavy engine noise and not answering the accelerator) When I accelerated hard, the engine began to respond correctly, but when I eased off the throttle the engine reverted to its previous behavior before cutting out. I had to fight this behavior in order to stagger back home. The car originally was converted from 4 star to unleaded petrol some years ago, and since then, I have occasionally put a little 4 star in with no problems. Sorry if this is a little long winded but I feel the more detail I give the better.

Answer: We suspect that it is carbureted. If so, you probably have some dirt in the carburetor. Try replacing the fuel filter and cleaning out the carburetor.

Answer:  Check your motor and transmission mounts as one may be broken or separated.
