hey guys i got this crx hf with a d15b7.and it runs fine when its cold but it starts to act up when it warms up.it acts like its running out of gas.wants to stall some times does stall and hard to start.i switched out the wires plugs and cap and rotor.im wondering if it could be the dizzy going bad its throwing no codes are showing up anyone have ideal what could cause this?

 

My old wagon was doing this, but it was from oil getting on the plugs and them not getting good spark. It would mostly do it to me between 1st to 2nd shifts and on acceleration.

How do your plugs look when you removed them?

 

new NGKr

and before anyone has the chance to ask no im not running out of gas!!!

 

What's the shape of your injectors? When I could get my HB running it was doing the same thing too but spark plugs were clean...seafoam seemed to have helped quite a bit running it through the tank and the intake....just an idea

 

well i would think if anything was wrong with inectors it would trhow a code.when i bought the car the guy did say something about the dizzy going bad.fyi it was leaking but i stopped that(he pinched the dizzy o-ring)
ill be changing the fuel filter tomroow sees if that helps any and ill be putting another dizzy on too.but kepp the suggestions coming.

 

Also service your throttle body and induction system... Use throttle body cleaner and sea-foam for the induction system. Works wonders

 

hum?yea i guess the t/b could use a cleaning.it still has stock air box i looked at the filter is looks good.

 

its fuel assys relay under the dash near the hood popper about 8 inches up the side of the dash a brown box with a big white plug in it. the soider cracks and makes the fuel pump cut in and out

 

hum? u must be talking about the MAIN RELAY.ive already chagned it out.

 

I had similar problems, but had misfire after warm up.

Here are some of the things I looked at

dizzy
timing
spark plugs
compression test
clean grounds
checked injectors
vacuum leaks
pcv
codes

coolant, ding ding ding
blown head gasket FTL, hope this is not the case for you.

Good luck.
