Need help: Misfire
1996 Honda Accord with F22 non vtec.
Codes:
P1300: Manufacturer Control Ignition System or Misfire
P0301, P0302, P0303: Cylinders 1-3 Misfire
1st I did was a compression test. All 4 Cylinders are 150- 160 PSI
2nd Replaced Plugs and Wires. (new) got the same check engine light codes
3rd Replaced cap and rotor got the same check engine light codes
4th Replaced the Ignition coil (new)- The coil with the
5th plug wire, exterior of Distributor. got the same check engine light codes
6th tested fuel pressure- 62 psi
7th tested if I was getting power to the injectors. Used a test light to one of the wires on the injector and turned the car over. Solid light and a blinking light while car was turning over.
8th Cleaned all the injectors. Used a syringe, fresh gas, and power to the injectors.
9th took injector #4 since it wasn’t misfiring and put it in #1. Still got a #1 misfire. #2 and #3 didn’t show back up yet.
Anyone with anything would be a huge help.

Re: Need help: Misfire
a lot of times when you got multiple misfires it's either the crank sensors are dirty or somehow bad.. you can also clean the two pulleys that the two sensors read off of while you've got the timing belt out

Re: Need help: Misfire
Do you get the code(s) right away or does it take a while/special conditions?
For giggles, have you pulled the EGR plate and check the ports - you had the injectors out so you are right there.

Re: Need help: Misfire
EGR Plate and EGR valve was clogged. I found another post some where and they mentioned cleaning the EGR Valve so I went to pull it and then I seen the plate so I pulled the injectors again and pulled the plate off. Let me tell you she was clogged!!! Fixed all of my problems.
