Well, after finally getting my engine to about where I want it and getting into the last stages of getting the engine running very good I am running into some more minor bugs. Something I hope you guys can help me with. First off, my engine is running excellent, and after recently replacing the transmission modulator (fixed my problem in another thread), my transmission is shifting perfectly. When allowing my car to reach to full operating temp and taking it on a little spin on some backroads, I am getting 16.9 in the quarter mile (with a friend using a stop watch). The car is also a breeze to drive daily now, and I've been driving it back and forth to school every day. I hope to go to a local dragway this summer and get a slip with the time on it so I can have an official badge of honor.
However, it was 85 degrees today, and I'm having the exact same problem that I was having a week ago when the temperature was 79. After driving my car across town to a friend's house or the store, then driving back to my house, I'm getting a massive hesitation at high rpms. Sitting in traffic, my temp goes up to about 75%-80% on the gauge. Then when getting back out into the country, I get a VERY noticeable hesitation at about 4000 rpms (right as I'm shifting into third gear). I had this problem last week when I was alone, but I had a friend with me this time and he told me that it felt like the engine wasn't receiving enough fuel. This only happens when my engine is hot on humid days, and (what seems odd) it only happens when in second/going into third gear. Not first/going into second. As soon as my tach hits 4000, the engine cuts out and stops accelerating unless I take my foot off the accelerator completely and let the car rest for 3-4 seconds. Then it's good. I was thinking vapor lock, but I'm not sure if this is a sign. Anyone else have this problem before?
