Hot air problem

[ehall85]

I've driving my car a lot lately because the cold air is making it run extremely nice, but it seems like when I floor it, it noses over. The car is 100% stock except the air filter. I'm pretty sure it still has the factory fuel pump, and exhaust so maybe those are my problems.. Any suggestions?

You're on the right track; fuel or ignition-related.

factory exhaust ,i would deffinately get rid of that , moisture produced by the engine will collect and sit in the factory muffler type setup ,especially if you have an inclined driveway , enough cold startups will effectively fill this cavity with water unless the car is run long enough to blow it out , even then it causes intermittant drivability issues . Besides rotting out the exhaust pipe from the inside out the flow of exhaust is cut down by the water in the muffler ,causing backfires , hesitation ,overheating . hope this helps , if you can elaborate on your description of nosing over it would help pinpoint your issue

Fuel pressure with vac line off?
New fuel filter?
Air filter clean/new?
Pump hot wired?
Plugs/wires in good shape?
Compression check/leak down numbers?

Getting air in and out , compressing it, mixing in the fuel and sparking it off at the right time, that's all it takes.
