Try a radiator flush with new coolant. Radiators tend to get clogged with **** and it can lead to the problems your talking about. What color are the tips of you plugs when you take them out. Have you had the codes read on the ECU?

    Did they pressure check it with the engine running? Theres only 3 places for coolant to go, in the cylinders which is usually burt and turns into white smoke out the exhaust, in the oil which turns it into a milky color, or on the ground. Are you always having to fill your coolant?

I have 98 honda civic dx I recently did a full tune up plugs, wires, distributor cap n rotor and fuel filter all was fine til about a week ago...it shakes for little when I 1st start it and engine light...


I would recommend testing the fuel injector if you are certain the spark plug and wire are functioning correctly. If the fuel injector is good run a compression test. If the compression tests fails motor is bad. Could also be an electrical problem if the motor tests good and only does this when the check engine light pops on. Might be a bad ecu.

wasn't contributing much as the other were

You got a bad wire or module or whatever your car has

Check the injectors listen to them with a long screw driver

1999 Honda Civic LX Stalling/Overheating!!!


(I don't know much about cars so bear with me).

I've had problems of overheating previously where my car's thermostat would hit 140. I think I've fixed the issue, I've replaced the thermostat but it was still doing that and 2 hoses blew and needed to be replaced. I've had to consistently fill my radiator with 50/50 antifreeze on a daily basis to ensure it won't overheat, so far that seems to be keeping the peace.

But now as of 5 days ago, I'm experiencing these new issues of stalling. Upon taking my civic into my mechanic, his meter showed that there was a misfire in the 2nd cylinder a month prior and now all 4 are misfiring. He thought it was the head gasket at first. I had just recently replaced the spark plugs with NGK Platinums, new spark plug wires and a new distributor cap.

I've received many possible culprits to my problem consisting of possibly the Throttle Position Sensor, Fuel Filter/Injection, Distributor or a radiator cap. I'm financially strapped at the moment and only could afford the radiator cap which didn't solve anything, however my radiator is running on 80% water at the moment. I'm really at a loss and I feel like I've done what I could and I'm at my wits end. Please help my poor little Civic cheat death for a little longer.

97 Honda Civic shakes at start and check eng light comes on.


It looks like misfiring in one cylinder. That is why check engine come on. Misfiring can be due to spark plugs/wiring/worn distributor cap. Maybe also vaccum leak and clogged injectors (use injector cleaner).

Please kindly let me know if this infor was usefull for you or you need more infro
Good Luck

Trouble shooting P0420 code, bank 1, OBD II for 2000'?


misfiring can cause a P0420 code.
I would recommend a set of honda plug wires and plugs if the P0420 code returns.
I have used bolt in aftermarket bolt in catalytic converters but don't remember the brand name they fit ok and i have had 1 or 2 return with a P0420 code out of about 20. I have never replaced the oxygen sensor on a civic like yours.
I always fix the misfire problems, reset the computer, and have the customer drive it and see if the code p0420 returns. 50% don't have the P420 code return. drive it and see what happens and go from there.
