I was test driving my friend's ef sedan i will be buying from him, but as soon as you hit 3k rpms, the tach jumps all over the place and the car bogs down. Im thinking it's the distributor, but i just wanted some other opinions.
thanks

 

My friend is having the same problem with his GSR.. We are looking for a new ecu, tell him to try that.

 

im 95 % it is the ecu makeing your car run like that cus my motor was acting up like that so i switched the ecu out and it ran better.

 

it could also be losing compression..that happened to my friends EK at 5K..ended up blowin the motor that same day..

 

i dont think it is compression, it runs strong up until 3k when the needle just starts to jump around and the car just bogs

 

i have the same problem....yes it is the dizzy...some guy read the ecu for me and it said dizzy and timing was fucked up in those exact words.

 

ah great thanks. il check out some junkyards this weekend.

 

is the check engine light on??

pull the codes from the ecu (lift carpet on pass side, turn key to ON (dont start) and count the flashes.

you will get 1 initial "on" flash, then count the flashes after that, then it will pause and start over.

3k rev limit = limp mode, could be a number of things, most likely the TDC sensor in the dist.

 

check the rotor button. Sometimes the screw falls out causing the timming to be wacked out.

 

yes the check engine light is always on, forgot to mention that.
what do the flashes mean? is there a distributor-specific code i should look for?
