ka idles at 3k - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Slammed Assassin · 08-06-2008, 02:38 AM

(backround info) I dropped in a dual cam ka because i my sohc blew..i had to do the timing chain so I put the first piston at TDC and installed the chain.. i got eveything installed in the car and started it up.

Could using a sohc ignition coil be part of the problem?

Problems.
-The motor idles at 3000,
-Motor shakes like crazy,
-Drove it around the corner and it feels like theres no power at all.(Slower than a golf cart slow.)
-Los of backfiring..

where you able to set the timing with a light? my friends dad did my timing chain and said it wasnt off because he was able to get it to factory timing with the distributor no problems. check with a timing light to see if you can get it close. i dont know though, because at 3k the timing would be different. maybe something is up with the throttle body and the cable. id check that out too. and vacuum leaks

ehh my motor shook really bad but turns out the rotor was bad. was even getting spark on one cylinder and it was slow. replaced the distributor, cap, and plugs and runs like a champ. as for the idle idk man.

check you tps sensor on the throttle body if that is way off it will cause the car to idle high or low also do what the rest of the guys said to its cheap and can only aid to fixing your problem

World's largest vacuum leak?

Slammed Assassin · 08-21-2008, 11:40 PM

(update).. i gave up for a while but i just want to get this done...i noticed that if i rev up the motor the idle stays at the rpm i reved it up to..then i noticed that if i push foward the throttle by hand in the engine bay the idle goes down to 1k.(i ajusted the throlle cable too to see if it would help. but no fix).any suggestions will be useful..thanks...

sounds like the throttle plates all nasty and sticky?

JRas · 08-22-2008, 01:20 PM

did you use the SOHC throttle cable? or are you using a DOHC throttle cable?

Slammed Assassin · 08-22-2008, 09:08 PM

im using a DOHC throttle cable..
