Question about 2003 Nissan Sentra
I have a 2.5 nissan sentra 02. Check engine light cameone day and car had a slight shake on start up, the code which read that there is a random misfire which then i used a block sealer because i thought it was a leaking head gasket or even worse cracked head. After the sealer the car started up fine no shake but then started to over heat after around ten minutes of driving and even worse when the ac is running. I have changed both upper and lower thermostats, and still no change. Its getting hotter and hotter everyday any Advice?!?!
The block sealer you used may have been too thick or too big. A leaking head gasket or cracked head is a rare cause for a cylinder misfire. Tryin putting a manufacture gasket back on and change the spark plugs. If that doesnt work, try checking your valves or pistons-- maybe you have worn valve guides or your cylinder wall is worn out.
