I need help i have recently had a problem with my Civic lurching on acceleration, and continuing to under load on the freeway.
then if i take my car anywhere and turn it off, it wont start when warm, idle vary weak to dying when driven longer than 15 minutes in the day.
It fires right up when its cold, and its still drivable.. But barely..
This problem started a month ago and heres what i have replaced since:
*NGK spark plugs/ wires
*distributor cap/ rotor
*Vacuum advance unit
*fast idle boost valve
*battery...................................HELP!!!!

when its not starting try looking under your pass seat at the ecu an see if there are any lights on then if so see what number its saying.

the not running well i have the same problem for about 2 months now its to the point the cars been parked as not able to drive more then 10 imins with out it shuting its self down to limp mode. havnet found the problem yet.

lurching on acceleration, and continuing to under load on the freeway.

A little more information please. Does this mean it is hesitant under acceleration? Or does it "stop and go."

How old is the timing belt? It could have slipped a tooth.

Have you cleaned the throttlebody recently? The butterflys may be sticking due to gunk in the throttlebody. A good shot of carb cleaner inside and out may help.

You may have dirty injectors. A can of injector cleaner can help.

When the engine is running do you hear a hissing sound? You may have a vacuum leak.

I am going to guess..... dirty injectors. But that is only a guess. If a can of injector cleaner does not help, you may need to pull them and have them cleaned.

Check for a fuel starvation problem.. Injectors? fuel pump going out? etc...

[badpenny]

Make sure your ignition wires are in the right order.

[RETROCRX]

CHECK/REPLACE THE IGNITION COIL......THEY CAN BE TEMPERATURE SENSITIVE.

Damn caps lock...

Hope that helps.

Could also be ignitor related, or be like mine and the wiring is going bad between the igntion and the coil. Run a wire from the black and yellow on the distributor plug straight to a hot lead and see how it does. Might be your TPS. Spark plug arching somewhere. MIsfire?

[~zeus~]

I'm betting the TPS is at least part of the problem and the other is TB/injector related. Oh yeah, when was the last time you changed your fuel filter?

[zakats]

so many things... thats the issue with old cars, if you don't know the maintenance record or have owned the car for a long time then there are a lot of possible issues, it's best to start with the regular wear items (fuel filters!) and work your way through the car, cheapest parts first.

[spliffmunsta]

my car has similar issues, zakats has a great idea.. what order would you people do this in? i hear a hissing so will do vacuum hoses first i guess, are they all the same inner diameter does anyone know?

[pissoffSi]

Yea i also replaced the fuel filter as well, the ignition cables are in the right order...
bogging under acceleration and under load mean any time i step on the gas with an attempt to go the speed limit of 65,
I drove to work tonight and it was jerking the whole way even at 60mph, then for about 10 seconds it was running like normal no bogging, until it started up again. I had honda techs check out the TPS and they said that wasnt the cause....That was before 400 dollars worth of parts and labor, now they say bring it back to the shop for another 80 bucks an hour.... money is tiiiiight. THANKS FOR ANY HELP

when i step on the gas to get up to speed, the car power is "jerky" as if i was stepping on the gas and letting off rapidly back and forth.
my idle is at about 1500 then when warm out it gets very weak. Im goint to try and clean the trottlebody today, and dump in some injector cleaner.
by the way how and where do i check my ignition coil ?

[RETROCRX]

Don't know how to check a coil.....but a replacement universal coil is cheap.

One like this coil link is about $40.

Basically locate the stock coil on the firewall above the brake booster/master. Unplug the connectors and remove it. Cut the plugs off the wires and join the 2 black w/ yellow stripe wires together, and join the other 2 together also (can't remeber the colour). Now here's the part I can't remember off hand. One of these pairs of wires go to the + terminal on the coil and the other 2 go to the - terminal. I'd have to check my car to be sure. then plug the primary lead that goes to the distributor in and you should be good to go.

The coil usually comes with some sort of mounting loop to attach it to the car somewhere. Use that to mount it and you are done.

I'll check the wire colours and locations tonight.

Hope that helps.

[cbstdscott]

It sounds more like a coil problem.

I'd like to add that it could be a clogged fuel filter. When was the last time it was changed? I've had that problem before, and that was my solution.
