when i first bought my em1 i felt it pretty quick & the rpms will climb up quick now i feel it slow like if something is holding it back and rpms take longer to climb up. i just replaced my spark plugs, dist cap & rotor. still need to change spark plug wires and fuel filter. i have a bad 02 sensor that i need to replace is that the problem? is there anything else i need to replace?

 

A bad 02 sensor can make it feel sluggish.
Alway start by fixing CEL codes.

 

yeah thats how it feels bro but i wouldnt have thought it would make it that slow lol is there anything i need to look into?

 

Be carefull on the lower bolt on the fuel filter. They are very very well known for a being a PITA. It also is quite easy to round off.

I had so much trouble, I almost said F it. I ended up using a crows foot and that did the trick after about a hour of fighting it.

How many miles are on it? Is it burning oil? Loosing compression?

I agree with Mcvtec, fix the o2 first.

 

also throttle cable adjusting/tensioning would help.
over time they seem to stretch/slack.

check your vtec fluid aswell

 

lol @ vtec fluid

 

a line wrench works the best.

 

Thnx for advice bro, my car has 97k miles & no its not burning oil only when i hit vtec lol

Ill check that thnx

I think he ment my oil frm the engine

 

Actually NO, they aren't always the best.

I woudn't have told him to use a crows foot unless it worked.


OP, that really isn't many miles at all. I am suprised to here you are haveing issues with such low miles.

I was going to say check the throttle cable, but forgot.

Good luck with getting this fixed.

 

Actually they do work good. I have a set if wrenches that I've only used to change out the fuel filter and I never once had much of an issue with that lower bolt. The ones that I have are offset so you have to keep flipping the wrench over, yes it's a little time consuming but it works.

Since I've had my 97 I've replaced it about 4-5 times already and I also just replaced it on my 99. I have always used purolator fuel filters and never had any problems.

 

I never said they don't work well, what I said was they aren't always the best.

I tried every wrench I could find. ( My dad has TONS of wrenchs) Noithing worked. The last option was a crows foot which did the job.

I was only giving the OP another idea of what he could use, if he runs into the same problem I had.


OEM fuel filters here.
