i have a 1988 crx with a d15 in it that i picked up for 200 bucks

it has been sitting for a while and im trying to get it running decent

i have drained all the old gas out and changed the oil 2 times along with tranny fluid

i have also changed out plugs

my problem is that it has a rough idle and hesitates very badly

any time i try to get it gas more then 1/6 throttle it dosent want to do anything and seams like it wants to stall

only thing i can think of is that it dosent have any back preasure


can this cause this problem?

it is currently open header


any input would be awsome

thanks

 

let me also add that sometimes it revs fine with no hesistation

 

anyone?

 

no 1

 

what codes are you getting from the ECU

 

the ecu isnt throwing any codes

 

Try changing the fuel filter, spark plug wires and distributor rotor, make sure timing is on and run some seafoam through it. Then you can complete the tuneup and go from there.

Edit: just saw you're running open header . Not having an O2 sensor will make your idle all screwed up. You may want to remedy that.

 

the car only has 1 o2 sensor and i have that installed

 

check the screw that hold the rotor in place it might have came loose or fell off and your rotor is just arcing all over inside

Ahhh, my fault I was thinking you were saying no header instead of open header.

I still say you give her a nice tuneup and see where you stand after that.

 

the little butterfly valve before the throttle body seams like it doent open very much when you give it gas


could that be a problem

the car idels fine but sometimes like 50% it does this hesistation problem


it also pops when u try to give it gas and it dosnt rev and u let off of the gas it pops


also i have had it where you cant rev past 3k and 4k and 5k

clean out the throttle body with a spray and adjust your tps..
