Question about Cars & Trucks

1 Answer

My 94 honda accord is dropping to the floor after about 4 pumps then I pull it back up with my foot and it has pressure again. It has a rough idle when I push the clutch in and has little power when accelerating. The master and slave cylinders are full and have been bled. What is going on?

I believe the two problems are unrelated. The clutch sounds like a bad master cylinder-an internal seal may be failing. Does it grind the gears, and difficulty shifting? If it's that bad, trey a new master cylinder.

Rough idle and low power-sounds like it is missing-one cylinder may not be contributing power. Pull the spark plugs and check them for proper gap and wear. If one appears different from the others, that may be the problem cylinder. If it is not firing, it may have black sooty deposits on the end of it. From unburned fuel in the cylinder. If you have a miss, check your secondary ignition: the spark plugs and plug wires and the distributor cap and the rotor. and the high tension wire from the coil to the top of the distributor cap. If all these are in good shape, do a compression test of the engine. This will tell you the internal mechanical condition of the engine. Good even compression on all cylinders is a healthy engine, and translates to good power output. Don't pay $150-200 for a test from a shop. Buy a compression test gauge for about $40 and learn how to do it yourself. It is quite easy. Here is one tip for starting: a compression test should be done with engine at normal operating temperature. Pulling a spark plug out of a hot aluminum cylinder head can strip the threads easy. While the engine is cold, loosen the spark plugs and then just tighten them back down a bit. Run the engine until it is hot. Now you can remove the plugs, without fear of ruining the threads. Proceed with the compression test. You tube or google for info on compression tests. Or a repair manual.

    little power accelerating-occurs to me this could possibly be slipping of the clutch-if this is the case, and it\'s not an engine problem, it is the clutch disc is worn too bad. clutch slip causes the engine to rev up, but speed stays the same, may jerk and lurch a bit as the clutch disc slips.

SOURCE: Bleeding clutch slave cylinder

i think youre doing the right thing. they are very stubborn to bleed because the hyd. line goes up high across back of engine before droppiing back down to slave cyl., trapping air. could try to gravity bleed by opening bleeder at slave, cap off of master cyl, full with fluid then it may start to come out after a bit. then try your process again. or can try to bleed at connections further up the line, working your way back to bleeder. hope this helps. be patient.

SOURCE: Clutch pedal goes to the floor.

you shouldn't br having those issue, its seem you done everything correctly, I would take that new master out and replace it with another new one, hope you still have the reciept. I've seen and have brought many manufacture default many of time because it has been setting on their shelves for long time. if that dont fix the issue check your line it may have small leak somewhere between the master to slave.

You need to PRE BLEED the master cylinder, or you may never get pressure. Parts houses sell little hoses for this purpose.

I have a 94 honda accord standard transmission. The clutch drops to the floor after about 4 or so pumps, I pull it back up with my foot and it gets pressure again. The master and slave cylinders are full...

If it loses pressure after a few pumps, either the clutch master cylinder and/or clutch slave cylinder are defective, or there is a leak elsewhere in the system. Also low RPMs and low power are usually due to the ignition timing being incorrect. An incorrectly installed timing belt can also cause low power.

I don't think it's a fuel problem. Sounds more like spark. Change plugs and wires, and possibly the coil pack. Also could be idle control sensor.

Computer for 94 honda accord, where is it?

the engine and transmission computers are usually under the carpet.of the passenger side floor/foot rest area. Remove the carpet, which may require loosening the door jam or trim areas of passenger kick panel. Once the carpet is pulled back you should see a large (and you'll find out soon, quite heavy) "bash" or protection plate. This can be removed by extracting the fastening screws to the plate and moving the plate to the side. There are two or three plugs in each unit. Depress the center of the tab and pull away from the unit. The transmission computer is the one with the prefix part number "28100" and the engine controller has a prefix of "37820". The transmission

94 accord ex. rough idle. wants to stall.

If it was running fine prior to putting the new exhaust on, then there is either a restriction in the exhaust causing too much back pressure or something didn't get hooked back up.

good luck

Rough idle when a/c on

it is normal for your car to idle down when the ac pump cuts in just have your timing checked and adjust your idle as necessary at about 750 rps at normal idle with ac off also just make sure they havent overtightened the ac belt and pulley.
