and i'm starting to think that it has nothing to do with the engine just some sensor or ignition problem. I think sense I put the new o2 sensor in it's now running rich but I don't know.

ok so I just did a compresson test on my car and there is no way that it can be running this bad and have these kind of compresson results.

dry cranked till gauge stopped going up
1. ? (was being stupid and put oil in it before i did the dry test)
2. 230
3. 230
4. 235

wet cranked four strokes each
1. 230
2. 230
3. 230
4. 280 ( I did it three times and this is what I got?)

So I'm really up shi-s creek. I do have a code 51 and I looked it up and have no idea what it means but before I had that I had a code 13 so I replaced the o2 sensor and then I had a code 21 or 22 forgot belive 21 so I did the check on the tps with the workshop manuel and it seemed to check out and now it is throwing me 51? Is this my problem and what should I do next?

Wow, this is getting really exciting.
Could you post some pictures of your compression gauge and vehicle please.

Once you get the cars dialed-in (compression, leaks, bearings, alignment, brakes) swap in new rubber and glass, you've got something which should last for years!

I believe you are not performing these compression tests correctly. You should have around 200-210 in a *brand new engine*. My 1989 Swift GTi shop manual says "standard" is 206.2 psi/14.5 kg/cm2.

And what makes you think it's running rich now?

Ok so I'm thinking about buying the suzukird high comp race pistons and I was just wondering if I ran 11:1 comp what gas would I have to run to have it work right.

I would definately sort out the "what is actually wrong with it" question before i went and bought high comp pistons. What if it is a sensor/wiring issue?
