95 Civic hesitates on accel

[CivRacer95]

WOW, my car just recently started to have these problems once I hit 140K. Good thing you asked the question, because I was just about to go and ask myself. Thanks Bruce Hunt. Late...

[Bruce Hunt]

I am to the point that I will now start swapping out parts from another civic that I have that works fine. This will be much like many of the mechanics that I have seen. I will keep you posted when I get the two vehicles together in a week or so.

Can someone tell me what they are gapping the plugs at?

My civic is having the same problem, at least I think, Whos civic is hesitating or not taking off without stumbling all the way up to 3000 rpm. And if you slighly give it allitle gas until you get past the stumbling does the car run fine. Did any-one try replacing the map sensor. Some-one need to find the prob.

[drock59]

yes, we need to find the problem. I dont know what it is, but if i find out i will post the ANSWER! unlike so many before.

Did any-one try advancing or retarding the timing, Being civic have a so-called (interferance engine) just a slight change of timing can cuase the pistons to hit the valves and cuase the valves to bend. SO if you havent tried to check your timing both when the Civic is first started and then warmed up do so. I believe that the timing is fine until the car warms up then is off just a bit there after, so try setting the timing advanced allitle if its off after the car warms-up this might solve the prob with the hesitation I will try and post the results. I also have some other ideas that may work so I will keep every-one updated on the results. I will get this prob solved for every-one and let every-one know how to do it.

Check your timing when just started and after warming up, when its warm It should be off allitle, IF so try advancing the timing a bit. Also I recommend cheacking the 02 sensor, map sensor, timing-belt/tensioner. I do beleave that the problem Isnt in fact coming from the distibutor thats just the first conclusion every-one make. Check and replace any and all if found necc. if this doesnt help replace the entire distr. I beleave that Its the incorrect timing being Civic have the so called (interferance engine) which means just a slight change in timing can cuase the pistons to hot the valves resulting in bent valves (which may be the hesitation). So try advancing the timing just a bit towards the firewall. I will do the same and post the results.

I hope what I noticed today will help some-one help us fix the prob.
1st things first, When I say hesitate on acell. I mean that it basically stumbles until I get to around 3000 rpm (thats If I slightly give it gas) Also when at idle and you hit the trottle it will stumble up to 3000 or so rpm. When I hucked up the timing light I noticed the timing was retard a bit so I adjusted it and I got it almost on the money. It still does it so I had an assitant hit the trottle as I whached the timing and when it stumbles the timing fluctuates with the stumbling. Has any-one noticed this or if not who nows how this can be corrected or what the prob is. Im really getting annoyed with this and need it ti be corrected. Some-one has got to know.

Id seriously check teh cat converter. If youahve other exhaust problems, that might be it.

[acoustic-sounds]

Nothing to do with cat converter or exhuast at all. Its the timing. MAYBE DISTRIBUTOR.

[Bruce Hunt]

OK, the problem for me is solved. Man I wouldn't have put the answer in electrical but rather fuel related. But the hesitation even up to 3000 rpm was the plug wires. There was a small variance in the resistance of one wire. Replaced them temporarily with wires from another Honda I have and bang the problem was gone. New wires for about $50 and a new car.

Bruce hunt,
way to go pal! i have been considering the plub wires for a long time but dont have the fifty bucks to blow on the wires. (student)

Is there any way to get the wires tested so that i know for sure before i get them changed??

[honda_luvr_2000]

ok in light of the final result, who in their right mind doesn't change the wires w/ the plugs?? sounds like common sense to me. would u get new rims and put old tires on them? or how about fresh food and a dirty plate. seriously people.

[drock59]

i supposedly got "new" plug wires the last time i tuned up my car. I took it to my dads mechanic. Not i do it all myself and will change the plug wires with the plugs.

Is there any way to get the wires tested so that i know for sure before i get them changed??

On my old civic I never changed the wires. Why change them when they work just fine.

[typerx7]

ok, i actually noticed the same in mine bruce. its a 94 civic 4 dr and i had the clutch replaced and regularly replace the plugs, wires, and rotor etc. my timing is perfect....i thought about replacing things just to keep my car going for a long long time....so i replaced the ignition coil, its 75 bux here. i have not recently felt that lagging or hesitation since....try it man it cant hurt...any new parts for your car make it run better anyway....oh and get the valves adjusted too, that helped me out...c ya
