Hey guys. So I've been having a problem with my 91 accord. When the car has been running for a while (over 15 mins usually) it would start to have small "stutters" with the RPM's and when you go to push on the gas from a full stop the RPM's will drop then shoot back up. Sometimes the engine will even cut out before the RPMs have a chance to come back up.

I've also noticed while driving (past that 15 min mark) that I'm getting fewer RPMs in general. For example, when I'm cruising at 60kmh I usually get to almost 2000RPMs. But past that 15min mark or when I start to notice the other signs of trouble (RPM drop after pushing on the gas at a full stop) then I usually get around 2500/2600RPMs.

I do also have a check engine light and a cel code of CYP 9 - Cylinder sensor.

Does anyone know what this might be? I've talked to a friend and they though it might be my timing.

 

Anyone? Any ideas would be greatly appreciated

 

it would be best to swap in a used distributor if you have a junkyard nearby...sounds like cyp and/or ignitor are bad

Is there a way to check the distributor? I'm pretty strapped for cash right now.

 

You just need to do some searching.

Alright. So I just tested the distributor and I'm getting average readings for everything except the CYP sensor where I'm not getting any readings at all. I'm assuming the next thing your going to tell me it to get a new distributor, haha.

 

Alright. Replaced the distributor with a new one and everything seams to be working well again. Check engine light is off and all is good. Thank you everyone for the help
