My car stalls when i just let it idle. And when it idle's @900rpm i have a very low vacuum between 14-15. And it sounds like's it misfires. I've done a compression test and this whas the result.
1 150psi
2 95psi
3 100psi
4 100psi

Then we did a leak down test and then this where the results
1 90%leak
2 75%leak
3 80%leak
4 80%leak

But when i drive the car it runs fine, it doesn't smoke, it still fast(drove ,5sec faster then when the car was oke on the 1/8 this weekend)
Only in low rpm's it runs bad. So what could it be???

 

was the compression test done at WOT? Those numbers sound way low.... all of them, and the leakdown is horrible. sounds like your rings are ****..

 

Yes the compression test whas done on WOT and a warm engine.
But wouldn'd my car smoke like hell if my rings are gone this bad??(it doesn't smoke at all, not even a little)


thanks jose

it sounds like you have some serious blowby. and it wouldnt necessarily smoke. I had a cylinder in a b18a that was pretty shot and I didnt have any noticible burn. But also, have you checked the basic things? like your plugs, how are they? you could also be running way lean.

 

have you checked the cam timing? it could be off a little, that can affect numbers a bit

 

The plugs are good(light brown). And the cam timing also. I've also done a valve adjustment. Couldn'd it be that my valves are burned or something???

 

you could have mis-adjusted the valves... the reason it oculd be pulling shitty vacuum down low is because the valves arent opening or closing fully

 

That whas i thought. But i have done a valve adjustment sunday.
