Could be head gasket or piston rings. Piston ring issues will smoke under load or when revving the engine.

Do a compression test.

check the compression in suspect cylinders. oil could be comming from the valve seals. check the oil level fuel may be contaminating it. oil should feel a little thick with no odor of gasoline. check the firing order its easy confuse wires when changing cap/rotor.

SOURCE: I would like to change a carburated 89 accord to

Unless you have a junk car to get ALL the parts to swap. its not worth the time and money. From the fuel tank, lines, int manifold, distributor, wiring harness, vac hose harness, computer, ect, the list goes on. If it runs OK leave it alone, If not, find another car.

SOURCE: 1996 Honda Accord Rough Idle Even After tune up

Perform a valve clearance inspection and adjust if necessary. Tight or sticking valves will cause a misfire or rough running concern. Note: Perform valve adjustment when the engine is stone cold. 4cyl: INT 0.26mm EXH: 0.30mm (V6 engine are hydraulic and no adjust necessary.) Also check for a sticking or stuck open EGR valve. For diagnostic purposes only: Remove the EGR valve. Place a business card over the EGR passage and bolt the EGR valve back on. This plugs the EGR ports and if the misfire goes away the EGR valve is partially stuck open and is defective.
Check for low fuel pressure. Check for low compression. Check cam timing. Check for a weak ignition coil. Also don't over look the possibility of worn or broken engine mounts which cause excessive engine movement and engine vibration. -hope this helps

My 93 Chevy truck 4.3 has a miss in it I replaced the plugs,wires ,distributor ,and rotor .and all of the filters ,and belts . And still have the same miss in it ? It starts perfect but idles rough .


you could have a burnt valve on the cylinder that's misfiring ! Do a compression test ! could have bad fuel injector ! What type of fuel injection does yours have TBI - throttle body injection , MFI - multiport fuel injection . Pull plug wires one at a time to see what cylinder is not contributing !

I have a 97 dodge caravan 2.4L dohc. I started with an engine code of p0303 and p0304. The vehicle has a rough idle and has difficulty accelerating from idle to 35mph. I've run several tests; 1, pulled all...


DTC P0303: Cylinder 3 Misfire Detected
Probable cause:
  1. Control unit software needs updating
  2. PCM or ECM faulty
  3. Fuel injector(s) faulty
  4. Ignition system - Ignition module, coil, spark plugs and wires
  5. Fuel system

89 accord dx starts and idles fine but hesitates


check ur timing -
MARK with a scratch tool or use a yellow majiuc marker to see where the timing is now then-

loosen the distributor bolts - if you have a distributor on that model and - turn the distributor one way - then the other and see if it improves. You can slightly tighten the bolts or carry a wrench with you and drive the car and see if a new position improves the running of the car.
Also - change the plugs if you haven't done so - check them to see how they look anyway.
You may have a flooding condition on your hands as well but that is a whole new thing - so stick with timing and plugs -

hope this helps

I have an 89 Honda Accord lx and it idles too low


The idle speed for my 88 accord lx is 700-850 rpm for standard idle speed. The stalling is a seperate issue. When were plugs, wires, air/gas filters and distributor last checked? How long has engine been running for when you stall? Is the temprature gauge high? Any lights coming on when stall occurs? I am not a mechanic, but a DYI'er. These are common questions I am always asked when troubleshooting my Honda. :)

89chevy truck runs roughly


Isn't it fuel injected? More likely:
Pull plug wires one at a time, the one that has no effect isn't firing. Bad plug or wire.

Running rough, wont idle, bad gas smell


Possible injector failure. locate by disconnecting injectors one at a time. The one that makes no change is the questionable. Status of spark plugs need chkg also. pull the plugs an the one that looks washed is questionable good luck

1990 Honda Accord DX 5 speed no power/2 cylinders not firing?


ok.....as far as the oil on them it is possible it is only the spark plug tube seals located on the inside of the valve cover,in fact if you can remember when you took the old plug wires off the boots of a couple propably had oil on them.now as far as the real problem I would recommend checking the timing belt it is possible it jumped time,its pretty simple just remove the valve cover(gonna replace the seals anyways)and top timing cover.roll the engine around and look for the cam and crank marks.if you need anymore suggestions or help let me know have a good day DB

Idle Speed


You cannot adjust the idle speed, it is a fuel-injected model.
