I finally have my s13 sr20det redtop running descent. I've been driving it on a daily basis for over a week now.
But............................................... ..................................................
1. Its still getting poor gas mileage (40 or so miles to a 1/4 tank, -200 miles a tank.)
2.When I change gears, or rev at really high rpms I have a slight backfire. It isnt loud like a shotgun, but its annoyingly noticable.
3. My engine will rev at 800 rpms at an idle sometimes, other times it will idle anywhere between 800 and 1500 rpms. For example when I start my car up it will be runnimng at 800 rpms, but when I get to a stop light it will be idling at 1200rpms. Or Ill shut the car off, start it up a couple minutes later and it will idle at 1100 rpms or so.
4. Sometimes when I'm slowing down, coming to a stop, or put my car in neutral when I'm driving, it will drop to 0 rpms and shut off. Every once in a while the rpms will fluctuate up and down a couple hundred rpms at an idle.
5. When Im driving it sounds and feels fine for the most part, for some reason in every gear from 0 to 4000 rpms the engine feels like its choking or holding back a little, then after that it takes off and goes. It still drives pretty good inbetween 0 and 4000 rpms, but just feels like the turbo is just spooling but not doing anything else, is that normal?
Im at a loss, I'm not sure what could be causing these problems. I didnt get the enginge professionally installed, I did it all myself, or with the help of friends.
I've checked my vaccum lines, I have brand new NGK Irridium pregapped spark plugs, that are for sr's. (pregapped at .26 I believe.) I have a new Z32 fuel filter. I set the timing to 15 degrees, adjusted the tps until my car ran at 800rpms at an idle. But right after I set the timing the rpms started to raise again, I pulled off the valve cover and checked the timing chain. It was not loose and the guides still look good, (at least the top ones). I even did a compression test the other day, all 4 cylinders were at 130.
If anybody has had any of these problems, or know what could be causing them, youre help would be grealy appreciated
