Accord hessitate slightly going from 3rd to 4th.

[Bad_dude]

Hello everyone,
My car 1990 Accord Sedan Auto. Every thing is stock except for the stereo system. The car is well maintained by myself since I got it in 2008. Here’s a [URL=”http://www.cb7tuner.com/vbb/showthread.php?t=188160″%5Dglimpse%5B/URL%5D of it. The plugs are NGK G-power, wires are new Denso, cap and rotor are OEM, EGR plugs cleaned 2 years ago and problem existed since I got it through today and wonder what is it. It’s not as bad lately but I do notice it.
Basically when I go on the freeway accelerating, every thing going smooth, until I get from 3rd to 4th gear. The Tach meter between 2400-2600rpm, and before hitting 3000rmp, I notice the meter hesitate and drop about 100-200rpm and the meter flick right back up to normal. It’s just a slight instant. I barely notice the car hesitate a little also. I wonder if it’s some thing any one has experience and has a fix for it?
I can’t think of any thing right now, possibly the igniter or the coil? But if those 2 items are bad wouldn’t symptoms be more consistent throughout.

Thanks for any idea or help.

it may be the igniter having a problem. The tach
gets its signal from there. with the tach dropping
may indicate igniter issue. have you tested spark
to see if you have a good blue spark? also check
the igniter itself.

I have checked the sparks and the using the Helm’s manual for my car and tested the igniter, all is good. This why it puzzles me. I think the igniter could still be bad after all this time, 22 years old and 164K miles. But what’s the point of the test in place that can’t 100% confirms it. I am going to the junkyard to pull one off a 94 dizzy next week. I don’t have $90 to drop for a new NEC or Hitachi. I don’t want to spend less for an aftermarket that last only 2 years either.
Any suggestion on other route to get an igniter that is affordable?
Thanks.

try the junk yard igniter. you may want the
coil to.Try one piece at a time.If the price
is right.get the whole distributor. keep us posted.

no oil in the spark plug wells?

you need to take into account that if the autobox is electronic then each time the car changes gear a signal is sent to the engine ecu to cut throttle while changing gears ? (just a thought)

No oil in the dizzy. To specifically put it, I would say it’s already in 4th gear when this happens. It’s only occur when I push the car. If I go easy on the gas pedal, this problem does not happen. I bought a OEM Honda dizzy a while back from Ebay, it says from a Honda Accord 91. The dude sent me the dizzy for an external coil from the 92. So it has only the igniter in it. Maybe I will try that. I don’t want to strip the screws that hold the igniter in place.
