My 98 neon can not speed up when it is cool. In spring, it will exhaust at 40-50km/hr, and in winter, it can not go to 30km/h before it get hot. The add oil light keeps come with the exhaust. Before 4km the light doesn't on, after, it will come and keep to about 12km. The service engineer soon is coming frequently. Sometime, it is idle speed lower, some time report fule system problem. I changed a new fule pump and it keeps same as before. I used fule system cleaner to clean it, no any improvement. Can you give me any idea? THX
