I took my car to Autozone for the check engine, it read code P0301, P0302, P0304, P0306, P0300, and P1399. The first five codes were for misfires and the last one is for the glow plug circuit high side and that I would have to take it to the dealer to get it sorted out. The car runs fine except at high rpm's, where it starts misfiring until you get out of the gas. My question is for the P1399, WTF is up with a glow plug, it isn't a diesel! Has anyone dealt with this?
PLEASE HELP!

did you ever find the problem? i have the exact same problem

get your self a EGR valve it is sticking or the EGR port is blocked i can tell you how to test it you have a volt meter but i am 100% THAT WHAT IT IS
Code P1399 is a pending misfire code.
HOW TO TEST

1. Check EGR position sensor voltage on the White/Black wire at idle - look for 1.1 - 1.2 volts with the EGR valve closed. If the EGR position sensor voltage is higher than 1.2 volts, the EGR valve is stuck open.

2. Can unplug the EGR valve and apply power to the terminal on the EGR valve that the Pink wire would normally go to and ground the terminal on the EGR valve that the Black wire would normally go to and see if the engine stalls at warm idle.

i just replaced the egr valve a month ago with a new oem one. could the new one be sticking or something? It started hesistating even more after a month of the new egr valve. I used to get a cel for the egr and it would hesitate on throttle every so often. I changed the egr and the hesitating started to get worse after about a month. The egr valve CEL went away though. I get misfires in all cyclinders, and the p1399 code.

did you remove the the intake manifold and clean the egr ports

not sure if a non honda scanner will give a data list like the hds. if so i would see what the map voltage is at ,sounds like a tight valve map voltage should be around 0.84-0.90 anything higher is most likely a tight valve and will cause a random miss fire code.
post test results so we can get a fix for you.

I started the car today and the thing runs like as*. It hesitates like crazy when you get on the gas. Anytime you get on the gas and drive it will just jerk back and forth trying to move. It feels like it's hitting a rev limiter.

Another thing it does is the speedo bounces around like crazy even when it's idling. Idle is fine but the mph just bounces around.


btw, i only changed the egr valve. I never cleaned the ports. I took the egr valve off today and the ports look fine where it was visible. I'm gonna try and take the manifold off and clean the ports.

I got a map sensor code too the other day. I got a new map sensor but it didnt fix the problem.

you need to test the voltage first lets us know what they are

ok just because it will show a map code it does not mean the map is bad it is simply telling the pcm and the driver their is a problem. we need more data info.

the early accords and acura's had a run of bad fuel pressure regulators and after a long soak the regulator would not hold the pressure and bleed back in to the combustion chamber and will also cause a miss fire code and the car would run like crude untill the engine cleared out.whats the fuel pressure doing ?
