When i sit at stop light the engine revs and seems like it wants to turn off but then rpm's drop to normal and everything is fine. I switched oil to Castro gtx high mileage synthetic change oil filter and put in new spark plugs. The engine has a little over 230,000 miles on it but we did compression test on the engine and everything is just fine and engine is surprisingly still running at full power.
