Slow Acceloration

Sebarbe · 07-04-2006, 11:08 AM

I have had my S2000 for almost a year now. It seems as if in the last few months the 1st gear acceloration isn't what it used to be. Any thoughts? I had Honda Accord before and the same thing happened. When I took it to the dealership they said it was the "Clutch Spring" and $175 to fix. Which to be honest I aksed a few people and nobody ever heard of a part. Before I take it back to the dealership, I wanted to see if anyone has any suggestions.

Hi Seb;
Okay, I come up with two things that godda be eliminated first: 1) it's not runnin' away in an obvious, or, maybe, not so obvious, clutch slippage, n' 2) you're jus' not gettin' too used to the normal acceleration n' lookin' for somethin' more.
Then the usual tune-up stuff rears it's head: first air n' fuel filters n' if that doesn't solve the problem, plugs, plug wires, n' whatever else is involved on Stewie to bring it back to fresh after too many miles. (Check your bible.
You don't want to be riskin' your car to second-hand information. Get it straight from Mother Honda)
Which brings us to the next question: how many miles have you put on it since you noted the lessenin' of acceleration? If you've gone a long time without much mileage I'd be thinkin' filters more'n anything else.
Good luck, n' find n' consult your bible. Keep it on the bedstand. You'll sleep better.

Also you could try a valve adjustment. This is suggested at various service intervals, however some owners like to check theirs in between.
The service manual gives the gap specs for this.

What fuel are you running? Is this the same fuel you always buy?

The other thing is, is it Summer where you are at the moment? Hot Summer air is generally worse for performance than cold dense winter air.

Without specific data you can refer to (eg times) it could be a psychological thing as Java suggested. A bit like how some people swear their car is quicker by adding an intake or something.
