Engine hell
 

After running for like 20 minutes my engine will start to sputter sometimes when i give it gas. Im think its the injectors are in need of good cleaning. But it only happens at speeds under like 35 mph. Usually when i give it a lot of gas (Past half throttle) is when it will do it...

did u notice the engine being a bit warmer than usual ? also what car you have will help me more

The car that is sputtering is a '90 Pontiac sunbird LE convert. Please i am in dire need of help thanks. And actually yes it does seem to get warmer especially when i stop at like a light i can actually watch the thermostat in my car go up and when i get rolling again it goes back down.

yup change the termostat, and do a cooling system flush. also check the water pump. that should take care of the problem.
