delayed accelaration LOOKING FOR ANSWERS

[zachnico]

i have a 93 240 with a dohc.when the car is cold it tends to be a bit delayed.ill push on the gas and it will kinda go but then all of a sudden rev up?im boggeld,if someone could help i would very aprishiate it.thanks

[zachnico]

i also have a injen intake on it with a breather on the crankcase,i dont know if theres something to do with that

hmm... have you checked the computer for any codes? also check the whole engine bay for any vac leaks.

how about the ignition system? is everything good?

[9240sx]

It does this when your moving?Or stopped.

[zachnico]

i dont know how to check the codes,if you could fill me in.also there is no vac leaks and what would i check on the ignition system?thanks

http://240sx.org/faq/articles/ecm_codes_doch.htm I don't know what up mean by rev up? idle fluctuates? When you step on the gas, it hesitates then goes..I'd just look/clean/inspect the usual suspects, any vacuum leaks,spark plugs/wires,distrbutor rotor/cap,even throttle body maybe its sticking gummed up.

maybe ur clutch is worn out

[zachnico]

no its not the clutch,the throttle bodys not sticking,just gave it a new tune up(wires,plugs,rotor,cap...etc......)let me see if i can explain this diffrent.ill start up the car,ill lift up the hood,ill open the throttle body with my hand and give it some gas,instead up it "reving" all the way up and and reaching high rpm it sounds like like it wants to bog out and the rpms stay low(even when i have the gas all the way open)this happens when im in the car also.

Check your throttle position sensor. My sohc had the exact same problem and when I changed the tps, it ran beautifully with good throttle response.

how does the car idle? I'm thinkin maybe one of the clamps is not on correctly or something creating a vacuum leak. if it only happened JUST after you put on the intake maybe double check everything for leaks.
