#1390 of 2262 Re: Comments on buying 98 Accord w/ 175K miles [trikev19]
May 12, 2008 (7:40 pm)
In the five years I've had my 1996 Accord (Since Aug 2002 when it had 125k miles), I've found an average of $300 a year does it for repairs.
Brake Master Cylinder, Radiator, Front left driveaxle, were the big-bill items. I just put a timing belt, balance shaft belt, and water pump in it for $425 (the drive axle was $300, and a new exhaust valve gasket-cover was $35, no labor since the engine was already torn-down to do the belt, which fixed an oil leak- all this was done a week ago for $760 total).
My car still tracks beautifully with no steering slack, and will do 100 MPH without protest (I had to go stormchasing the other night and had to get to the TV Station in a great big hurry! - traffic was light and my 180k mile Honda was ready!). I live in Alabama, and my mechanic told me "I'd drive it to California, today."
I would too.
#1391 of 2262 Surging tachometer
May 15, 2008 (1:23 pm)
I have a 99 Accord EX with 59k well maintained according to the Honda manual. I just came back from a 300 mile round trip to my parents and couldn't help notice while cruising at 70, no head winds, no incline my tachometer jumps from the normal 2500 rpms to about 2800 rpms sporadically and then resumes back to 2500 rpms. Is this normal? Elroy and others have given good advice for others with questions. Appreciate any input.

That sounds like the torque converter locking and unlocking to me, based on the RPM speeds.

Providing that it is what you say it may be, is this an easy fix and at what cost? I can live with it, just don't want to damage anything. When cruising 70 the tach reads at 2500 and remains there for the most part...occasionally it will exhibit the symptoms posted earlier. Thanks.

I honestly don't really know. I'm wondering how truly "problematic" it is.
I was hoping some of our "in-house" mechanics would chime-in soon. I'd stand-by and wait for them.
The only thing I can really think of that would be causing you a problem is the increased fuel usage, and if it isn't doing it often, then I can't imagine it is too big of a deal, but I'm really NOT the expert here. I have a couple of Accords, but have never worked on them myself beyond replacing their air filters.
I imagine some more knowledgeable people will be posting here soon. In the meantime, maybe try posting your question on "Edmunds Answers," one of the new features on the site.

I've heard of the tachometer surge problem before, but for the life of me I can't remember what the cause was. Maybe do an Internet search. Is the engine also increasing rpm, or just the tach needle jumping up, with no change in engine speed? If the engine speed increases, does the car speed up, or stay at the same speed. The answers to these questions could tell you if the transmission is slipping, or there is an electrical problem.

The car maintains the same speed. Thanks.

The car maintains the same speed. Thanks.
So if the engine is turning higher rpm (is it?), the transmission is either slipping or downshifting.

I didn't detect anything different or sounds in the way the car drove other than the observation of the tachometers surges. Thanks.

In a Camry, the torque converter lockup is like adding another gear, and is done for fuel efficiency. It's computer controlled.
If in lockup, and the computer is sensing it is going to need to downshift to maintain speed, it will unlock the converter, and the rpm's raise by a couple hundred rpm's. A number of times that is all it takes to get mph back up, because if you look at an engines HP and Torque output curves, you'll see the higher the rpm the more HP and Torque the engine will put out.
If the incline is too large and the mere torque converter unlocking doesn't maintain the speed, then it will downshift the gears. Older transmissions never even had transmission lockups, it was developed for FE, and removes 'slippage' from the converter.
I don't know if a Honda is the same or not. However in a Camry, a torque converter unlock is a perfectly natural action.
