PLEASE BEAR WITH ME! I'm sorry for the long post, but I wanted to be as thorough as possible.
Where to begin? I have a 2001 JDM B18C. I have an ebay chipped ecu with a basemap, 9k redline, and 5000 rpm vtec crossover, and an OBD1 B18B dizzy. (I was running the Type R dizzy with a conversion harness/pig tail but the cylinder position sensor went out on it, so i just took a spare B18B dizzy I had to work and milled the bottom two mounting tabs off. Works like a charm.) Also, these problems were occurring while still using the stock dizzy.
After driving the car for about 30 minutes, it will start doing this weird stalling thing when taking off from stops. I'll let off the clutch, and at about 2000k the motor will lose all power. You know how when you have the car in gear, and you just let off the gas, how the motor just winds down? It's pretty much what it sound like. I'll spell it out for you, bear with me here.
Start accelerating: vrooooooooooo- *shit starts fucking up at about 2k rpms while still pressing the gas* broooooooooooooooooooom *Until the car stalls out, or I clutch in and pump the gas pedal like crazy, rev the motor up, and drop the clutch*
If I just keep my foot down the entire time it's acting up, it will eventually pass (most of the time) after about three or four seconds. When it finally catches, It'll throw me back into my seat and haul ass. I've also noticed that is seems to miss a little bit in the high RPMs in third and fourth gear around 7.5k. It sounds kind of burblely, like a really fast bub-bub-bub noise. It's barely noticeable, but it's there. Occasionally, when shifting into fourth right below the vtec crossover, it will sound COMPLETELY different when it mashes VTEC normally. 1st-3rd gear are usually really high pitched, and fourth is usually, but sometimes it sounds kind of muffled. WTF? Everyone I know says my car runs too rich, because when I gun it, I throw out black smoke, not ALOT, but enough to notice.
I looked at the plugs, they had a lot of nasty brown crusty shit on them, so I cleaned them off (I bought new NGK's but they gave me ones for a LS, and they would have to special order B18c5 ones.) The wires look okay. They don't show signs of arching. I originally ran the swap with a P28, and it ran like a CHAMP, surprisingly enough. Idled great, ran fine, the only downside was I couldn't rev very high. My friend SWEARS that it's my egay chipped ECU that's causing the problems, because they used cheap components to chip it, so when it heats up, it causes problems. I have my doubts about this theory, since it ran great for the last four months, and I took the cover off to give it more air. I've touched the components to see if it was hot (In traffic, while my car was acting up) and the resistor's and chips feel pretty cool. What gives?
It's annoying and stupid dangerous, especially in Austin traffic, where people like to ride your ass. Someone HELP!
