I did a search, but there wasn't much to find. My guess is the fuel filter. This just started a couple days ago. When I'm at low RPM (1500 or so) in 3rd, 4th, or 5th, the car stumbles. Now its getting worse, it does it in first gear and its moving up in the rev range, its doing it at 2000rpms. Is there anything else it could be? I also need to replace the PCV valve, but I don't know if it would cause this. I check the spark plug wires and everything seems fine. Cap, rotor and everything was done at 90K (130K now). Anyone have any ideas? I'm gonna try resetting the ECU too.

Punch it and see if it boggs then goes. I really dont know what to say. But I guess performing some routine maintaince might help.

I prolly couldn't help you unless I was there and rode in your car.

 

I'm not totally sure on this also, My car tends to boggle alot below 3000 rpm on any gear. I change the basics, spark plugs, fuel filter, oil change. etc...but still tends to boggle...I think my teg body just too heavy and with a 7 year old clutch, it just normal for me...but I dont know. Any feedbacks from others would help the both of us.

One of my buddy has a s2000 and his car choke/boggle on him espcially on 1st gear from rpms 0-3500 and after 3500 it runs normal. He took it to honda, did a diagnostic test and they told him, it was his o2 sensor on the cat that was burned and thats why his car boggle.

any feedbacks...i dont think its my o2 sensor though.

 

I also have a question about this...

92 Si hatchback....bogs off the line after launching at about 2500. It didnt used to bog so much 3-4 weeks ago. I've done a tune-up, oil change, etc.....still bogs. Anything else to check?

 

here is a little update: I was in 4th at about 1700 and it shuddered/bogged or whatever, up till like 2500 or 3000, and my A/F (Autometer disco party guage) was going with the sound of it. My car sounded like a Harley. It was SUPER slow and didn't wanna accelerate at all, but above that rpm range it was fine. The car pulls hard and A/F guage reads normal (2 LED's in the rich side) under WOT. Does this help? Any ideas?

kinda sounds like an o2 sensor....with the A/F meter flying around with it, i think it would be possible that might be the culprit...

 

well, f***, how much do those run? $100?
