EricTheCarGuy first of all id just like to say that your youtube videos are amazing! Im still learning how to work on cars and your videos are very descriptive for people like me trying to learn. I’ve been looking around cause i have recently bought a 1991 honda accord 2.2 automatic. It has alot of issues but i paid 300 bucks for it so cant beat that. Id like to say that there is no check engine light on. The cluster seems to be from a 5speed tho since it does not have the pnd123 gear boxes on the cluster so i dont know if that would cause the light to not come on. I will try to explain my problems the best i can and the best i know so far. When i got it i drove straight home, ran like complete crap, has absolutely no power, barley makes it up hills, misses real bad and backfires, seems to have a hard time shifting gears, and smokes out the exhaust. When i got home i shut it off, come back out maybe 5 mins later and it would not start. Next day it started again but the idle problem was way worst. I put new plugs and wires and tightened that plastic screw type deal inside the idle control valve and the end of the intake. Seemed to help the idle and start problem. When i put it in drive the rpms drop to about 2 or 300 and starts shaking extremely bad and still has no prower and feels as if it will die but its not died so far. I have no idea on what to even start doing, everything online tells me so many different things and i have very little money to just go out and start buying tons of parts that may not even be the issues. Please any help would be greatly appreciated.

You could have mechanical issues. see if these links help.

Today i did a compression test. 1st cylinder was 135. 2nd was 0. 3rd was 110. And 4th was 135. What would cause the 2nd to be 0? Maybe a stuck valve? And even the 3rd be at 110. There all supposed to be around the same right?

They should be the same or within 20% of each other. Stuck or bent valve.
before you get gung ho on the engine, redo the compression test on the bad cyl. However put a little oil in first before the test.
if you get compression the rings are bad, if you don’t the valves are a likely candidate. make sure you don’t have a spun bearing, otherwise it may just damage the valve again if you get the head done.
That is if the car is worth going this far. I don’t know how the cars are where you live. I can always pick up a running beater for $500-800 CAD. Better to eat the $300 then sink $500 plus in a car you can buy working for $800. (and need no major work.)
Good luck.
I did the comression test again with oil in the one that had no compression. It was still the same with 0 compression. When i do the test, all the other 3 that actually had compression sounded like it was trying to start.. The one with no compression did not sound like that at all.
Is the timing belt new on the car? Now it’s time to find out how the valves got damaged. Brunt, spun a lower end bearing, or bent do to a failed timing belt.
The timing belt is not new. The car belonged to my sister before and during the time she had driving it back and forth to work and wherever, the timing belt never broke on her.
can you borrow or buy a leak down tester? That will help you make sure it’s the valves at fault, for loss of compression.
Or you can just take the head off and have it checked out.
I can try to see if i can borrow one from advance like i did with the compression tester. Car will not start now, so is it something i could use with the car not running?
with a leak down, you put the Piston at TDC. hook it up to a air compressor. and listen for if the air is leaving the intake or exhaust.

Alright. And another question. Before i did the conpression test the car would start and run. After the test i cannot get it to start. I pulled all plugs out at once, then tested each cylinder. Put all 4 spark plugs back in and it wouldnt start. Did i miss a step? Maybe i should have unhooked the coil or something? Would anything during the test result in it not starting now?
Maybe the coil should be unplugged and grounded, to keep it from frying. there is a video on here to show how to use a leak down, have a search for it. there is a TON of info in the videos here.
You would probably be ok to remove the valve cover and see what you can see. If three of the cylinders are ok then you may have a mechanical defect associated with the intake valve for the bad cylinder.
No compression on one of the cylinders?
Bent valve would be my first guess. HOW it got bent, who knows. Could be a timing belt problem.
It sounds like something where you are going to need to pull the head to inspect the insides.What you could do before removing the head is remove the valve cover, rotate the engine manually (using a large breaker and socket on the crankshaft pulley bolt) and watch the valves from atop. This is an overhead cam engine yes? Bent valves will not want to come all the way back up.
I doubt you messed anything up by doing a compression check. At this point, there isn’t much you can do to make things worse anyways.
It is also possible that the timing belt tensioner is messed up. Maybe rotate the camshaft at the bolt back and forth to see if there is considerable “play”. I mean don’t force it like you are trying to rotate the engine but just an easy back and forth rotation.If everything else fails and you decide it is more work than you can or want to get into, you can scrap it for close to $300 so not like you would be out much. However, if you see that as an option, might as well take things apart to see if it is something you can fix.
