I have been having this hesitation problem with my 91 crx si. It only happens below 2000rpm, anywhere above, its fine. I cleaned the injectors yesterday and took out the plugs and cleaned them too. can anyone help?? i really want to go the the track, but this is holding me back.

 

my si used to be the same way I changed the fuel filter,plugs,wires and cap and rotor and I also had the timing checked. Try changing the oxygen sensor if possible. Mine started running alot better after the the first stuff was done.

oh I forgot to tell you to check the codes.

 

I changed my fuel filter recently, the wires and plugs are also only about a year old. Ill change the cap and rotor. My t-belt was changed about 5k ago...could the people who changed it have messed something up??

 

I doubt they messed anything up but changing your oxygen sensor could also make a difference. Check the codes also heres what they mean.

ok, ill get them checked, thanks a lot for the help

 

Oh I forgot to say you can check them yourself heres how. there's a led window under the passenger side carpet.
Just roll it back, you'll see the window. Turn the igintion to on and count the flashes.

 

Did you put your plug wires all the way in??? I know this sounds stupid, but sometimes the metal inside the plug wire boot comes out (usually in cheap wire sets) and you just can't put it back in. Then the wire won't seal at the top like it should. If that's the case then ya gotta by new ones. Just something to keep an eye on.

 

they're NGK plugs and wires, and everything seems to be alright with them, but i never knew that could happen. thanks

 

ok, not throwing any codes...My sister has a 92 prelude and she had the same exact prob i do. Her check engine light came on, so she checked the codes and it was the O2 sensor. My engine light isnt coming on though....so im guessing i should just change the sensor anyways??
