Hi guys, I'm new in the forum, by the way is the best honda forum of the hole world. I'm from Argentina (yeah, it sucks) and, at the moment, have an 1988 civic hatch all stock (d15b2 dpfi). Let me tell you, the thing is driving me goddamn mad. I just replace de TPS because I was getting a code for it and also replace de o2 sensor with a brand new one cable ntk. I cleared the codes and everything is alright until I put the gas to full throtle, then the check engine light wents on and the car starts running like crap. The code I'm getting is, again, code 1. I can't really understand what the heck is happening to this s**t. To make it clear, the car runs great until I floor it, then the CEL goes on throwing code 1 and the car starts running pretty bad, like with no reaction at all. This only happends when I get, for example, on to the highway, or whenever I'm driving above 50mph. Please help guys, I'm really going mad over here. In my country no one nows nothing about hondas, specially this old *** one. Need help urgently, thanks
