I have a 98 civic lx manual and whenever I’m in the lower rpm range (below 3700 or so) the car is really sluggish and doesn’t really pick up until i’m passed that range. I have replaced by fuel pressure regulator and that seemed to fix it a little bit. I’m thinking of to replace my fuel filter next.
What do you guys think?

Coolant was draining like crazy and car would start to over heat. Add more coolant, temp went back to normal. After driving but 30mins or so, car would start to over heat again.
That sounds more like air in the cooling system. Unless you test for a head gasket failure you really can’t assume that you have a bad head gasket. First bleed the air out of the system and then check for a head gasket failure. You can use these videos to help you with those procedures. Don’t make assumptions, it gets expensive.
Bleeding a cooling system
Checking for head gasket failure
The videos that you posted didn’t work. Also, air in the cooling system would drain coolant:blink: I’m also gonna re-check the timing belt and count the teeth on it again.
Air in the cooling system causes all kinds of issues, trust me on this. Draining coolant has nothing to do with it. In actuality the #1 cause of engine overheating IS air in the cooling system and it should be the first thing to be checked when diagnosing an overheat condition. You can’t condemn a head gasket without some evidence to that fact. The above video should guide you with that. I’m also not a fan of stop leak. I’ve seen it cause more problems than fixes.
If the videos didn’t work download the latest flash player for your browser and recheck. They show up on my end just fine.
ive never known an additive to the coolant system ever work on head gasket failures and believe me ive seen it a hundred times where my costumers have tried it before calling me out ? like eric says it would more than likely be something else on the cooling system ? and additives do cause a hell of a lot more problems than it will ever solve.
