my d16y7 in 98 civic lx it stalls or hesitates if i step on gas hard / a lot after it warms up itll cut off if i hold it if i dont itll bog / want to turn off what could this be TPS?


I order tune up kit from online with good brand names, should be here soon ill install all things then see if that works but what could be the issue? i just hit 103k miles purchased the car a few months ago at 99k didnt do anything to it.

i think its all complete bone still stock with no timing belt or anything done

shed some light could my car need a tune up or should i purchase a new throttle body to replace tps? or better yet do a y8 intake mani swap

 

cels?

 

O2 sensor down stream I replaced it and cel still on after I clear codes.

 

downstream o2 is just a cat monitor. provided fuse 15 isnt blown in your underdash panel, your cat may be the issue.

 

First off, you don't have to buy a new TB to get the TPS. There are companies that sell just the TPS. Second off, give us exact CEL codes. If you don't have a scanner, then blink codes are fine. If you aren't 110% sure about the blink codes, feel free to upload a video to Youtube so we can see them. Third, if you replaced the secondary O2 sensor, and the code didn't go away, then either you didn't replace it correctly, or you didn't reset your ECU correctly, or there's something wrong other than the sensor (but that still wouldn't cause your symptoms).

Check your TPS sensor before blinding replacing it. You can find a how-to here.
