Ok so i have a 97 civic ex coupe 5-speed. I just got the car and dont know much about it. It does have headers and a cold air intake. When i get to 4500-5000 it acts like im hitting the rev limit. I thought those cars came with a d16y8 bit the numbers on block say d16a. The ecu is a p2p-a33. The car was running rich and showing codes for multiple missfires and i founf someon had put a resistor in the iat. I put an iat on it today and drove it 100 miles after resetting codes and so far no codes but the car wont get anywhere near rev limit. When i get to 5000 it starts loosing power and won't speed up til i hit next gear. The car will bark tires bit is still sluggish. I used to have a 94ex 4door and it was way faster then this car and it was bone stock. I am wondering if it needs a different ecu. I replaced the fuel regulator and the coil and plugs. Still no luck. Really hoping someone can help. I cant afford to keep changing this and that. I cleaned where the map sensor is and checked the screen on vtec and it all looks good but its not working. I put full synthetic 5w30 in it. I just know i am tired of a focus at work stomping me and everything else for that matter. I have been trying to replace my civic for years.

 

A focus? Dude, that's lame.

 

Does the check engine light work? Is it on?

 

didn't bother reading this paragraph title suggests limp mode

 

it stops going faster till you hit the next gear? sounds like your driving a 5 speed....

 

Thats funny but why is it running in limp mode? The check engine light works and isnt on.

 

Last codes i had before clearing were 02 and multiple missfire
