A new issue has arisen with my starlet, and that is when i went to start my car this morning it struggled,eventually it did start after I pumped it a couple of times. I have had this car for 7 years and never had any problems. I recently had the middle box on my exhaust replaced and it sounds awful I don't know if that has something to do with it or not,I've bought a new battery, New spark plugs, coolant and air intake sensors, and now I'm stuck please help.
