I'm going to have my buddy do the compression test this weekend and hopefully thats the problem. I guess he just assumed that would fix it.

Oh I'm not sure about those sensors.. I'm going to check them myself.. And sorry it is a belt not a chain.

how many miles are on the car? i've seen cars with about 100k miles or more and the fuel injectors are shot. If one or more of those are bad then it will casue a misfire.....make sure those are good

i would take those out and check them to make sure they are not blocked or corroded or something like that. Might as well if you haven't figured out whats wrong with it.

Ok guys so heres the update.. I had the car towed to my buddy's spot and while I was there he did a compression test. The No.1 - No.2 - and No.3 cylinder didnt even move the needle on his guage.. the No.4 cylinder held at about 150.
He said he had to go in and see what the damage was gonna be. Anyone have any guesses?

btw, you need to find a new mechanic. i can't believe the guy did so much work yet he still doesn't know what's wrong with the car.

Re: Code P0301 Misfire on Cylinder 1.. Help
I hope I am not hijacking the tread, but my 2000 Accord (2.3L) also has the check engine light that comes on now and then and when checked, it's the same code. What puzzles me is that I have changed ALL the basics except the fuel filter and injectors. My car has 220k, runs fine, but has deminished MPG's and sometimes at idle, it sounds like my wires are crossed (other times, when cold and at random, it sounds great). Every once in a while, coming to a stoplight, it acts as if it's going to die at idle and is idling even more rough.... anyway, I can continue rambling about it, can anyone enlighten me?
Thank you ALL in advance.

I'm having the same thing going on with my car at first i thought it was the o2 sensors.replaced them then no change. then i had a code p0172 so i went to autozone and we down a list on what it could be. we came down to the fuel injectors so i just replaced them,and the car is still running like poo. now it has a code p0301 miss fire on 1 cylinder.... now what iv done b4 this problem. iv changed the timing belt about 6 months ago. iv had a small leak in the head gasket that's been getting worse. i was going to do a engine swap but i thought it would be to hard to do. so im about to take the head off and change the head gasket and get the head resurfaced and valve job. does anyone know if im just wasting my time or just go through with it. oh yeah i have a 2003 honda civic lx 1.7 with 281000 on it
