[chantheman]

check your fast idle valve and have you checked you distibutor cap and rotor button

[chantheman]

i havent check the fast idle valve yet but i will be replaceing the distibutoit cap and rotor this weekend thanks for the help.

might have a clogged fuel filter... trash in the gas tank, faulty tps..... check the codes on your ecu.... long beeps are 10 short beeps are 1... get on google and look up the CEL codes....

my eg8 did this exact same thing, i replaced everything i could think of and then some. did all the above that everyone said. it was my o2 sensor on the header, was completely shot. check that man.

[chantheman]

hey thanks for the info i will be checking these things soon

[SX-MAN]

yes check all of the above also check fuel pressure..... could be the pressure regulator.... the main fuel relay and also check all of the ground wires.... motor to frame trans to frame and it helps to make a couple more

injector..

juss sayin.. had the same problem.

take a long flat head screw driver and put the tip on each one of the injectors to see if u can hear each one of them clicking while the car is on. when u find the one that isnt ticking, lmk lol!

try and see if the rotor button is wobbling, sounds stupid but just double check that too.

[SX-MAN]

y use a screw driver to check injectors..... multimeter......just sayin.......and could possibly be the dizzy.... it has three sensors in it... one of mine went out and the da sounded like a scooby.....

where you located? if you cant yourself, a local tuning shop would be able to help you weed it out if its throwing codes. they're kinda tricky with da's not being obd2 wich uses a simple plug and play scanner. have someone run your code and if its not throwing any start asking around.
