I appreciate your help!
I gotta 97 maxi, and when i step on the accelerator, i have a bit of hesitation, sometimes its as if i have to force gas through. it does not chugg, or stop and go but it used to shut off and rough idle until i replaced the MAF (pepboys told me it was bad, no code) and the knock sensor (pepboys said it was bad too, code). I've done research and replaced the engien coolant level sensor and its never run better, however I still have a bit of hesitation and a drop in RPM when accelerating. I can tell I do not have consistent power, because I get a surge of power and other tiems I do not. car does have 220k miles. I also replaced the air filter and had an oil change done. Also had the fuel filter checked and it wasnt clogged, and I put lucas fuel system cleaner in and had the throttle body, and intake cleaned, along with the idle air control valve.

What gives?

thank you again

 

Is the check engine light still on ? symptoms your describing sound like a bad coil pack .

 

Pick ONE thread for your issues man...gives us all the info...and keeps you from getting confused as well.

Decrease of rpm at highway speeds and "bogging down" when engine is warm is a symptom of catalytic converter being clogged...as we told you in your other thread.
