rotaryguy481 · 04-09-2010, 08:06 PM

Ok I finally got it to stay running and everything I have been posting a lot on here lately I changed the spark plugs and now it runs but really slugish and popping and all what else could it be

Wicked vacuum leak, blown engine, timing WAYY off, bad gas....

Alot of variables.

rotaryguy481 · 04-09-2010, 09:02 PM

Well I know the motors not bad less than two thousand miles on it and would a blow off valve not hooked up right cause a big vac leak and the gas could be to and the guy i got it from mixed way to much oil with the gas as well.

A BOV could cause a vac leak, but I don't know if it'd cause the car to run sluggish and backfire.

Was the motor broken in done properly?

rotaryguy481 · 04-09-2010, 09:58 PM

Yeah im pretty sure it was what are the requirements

rotaryguy481 · 04-10-2010, 08:57 AM

jerd_hambone · 04-10-2010, 10:07 AM

Hm.

rotaryguy481 · 04-10-2010, 03:25 PM

I'm starting to think its the afm or bad coil or wires cause when you touch where the boot meets the wire it shocks the piss out of ya

My5ABaby · 04-10-2010, 03:48 PM

Did you put the right wires on the right plugs?

rotaryguy481 · 04-10-2010, 07:10 PM

IS L1 AND T1 the front rotor and L2 T2 the rear

rotaryguy481 · 04-11-2010, 11:10 AM

Ok I unplugged the pressure sensor and it runs just fine but when I plugged it back in runs like crappy

rotaryguy481 · 04-11-2010, 08:07 PM
