Check you coolant and coolant temp when driving
Check the transmission fluid
Check the fuel filters.
Check engine oil just in case
Oh well are you auto or manual?
Also check the vacuum line to the secondary diaphragm
Also check the carb venturi's since no fuel will cause the car to die.
A loose booster venturi will cause problems when trying to accelerate, and while driving, you can use the process below to check for a loose booster venturi.
THE BOOSTER SHOULD NOT MOVE AT ALL, IF IT MOVES WITH FAIR RESISTANCE IT MAY OR MAY NOT BE A PROBLEM... BUT IF IT"S VERY LOOSE THEN IT MUST BE TIGHTENED

do those screw only hold the venturies on then A20A1??

holy shit you had no coolant. damn better keep up with you fluids. or you'll be sitting on hte side of the road. glad its fixed now.

Ahh, that was #1 on the list

Um, just a follow up... you may want to check for leaks (hoses/waterpump)... and make sure the fans are working... as well as the thermostat.

Hi Guys:

My 89 Accord is having a problem. When I reach 3,000RPM and beyond, the car studders. Doesn't matter what speed I'm going. I thought it might have been clogged fuel filters, but I have replaced those and the problem still remains. I also replaced the spark plugs. The cap & rotor are also new. What would you guys recommends I inspect? I thought it might also have been the fuel pump, however that was replaced about 60K miles ago.

Thanks for the help.

I just got my car back from the shop from a similar problem....check your fuel injector grounds, and all your fuel based grounds....turns out mine came loose, and would cause it to kick in and out past 3krpm...hope that helps.

[A20A1]

He has a carburetor... his sig says LX and DX, plus carb has the 2 filters.

Thanks for the recommendation. I forgot to mention that I had replace the carburetor about 4 months ago. I doubt it's the carb, but at least I have a warranty on it.

Would the fuel sending unit be something to look as well? It's the original that came with the car. Today, the car stalled on me twice. On restart, I did have to crank it for a long time before it started.

Thanks,
Claude

Maybe the pumps giving out.

The fuel sending unit? you mean for the guage cluster low fuel light? I don't think that will effect anything, unless you believe your tank is empty when it says its full.

hehehehe, that gauge sucks on my car now cause when i fill up my car, it says i have 3/4th of the tank left, stupid senders and stupid gauge.

Mike could it be the fuel pump relay? or is it just the cut off relay?

[A20A1]

The cut of relay should have no affect... though the chiltons I believe tells you to remove it when testing the fuel pump... hmm.

what about air filter, that's what mine's was when it was clogged.
