Flooding Problem!!!

Hey all!

Got a questions for whom ever can help me.
I have a 1994 Z28 Automatic, i put a new Mass Air Flow Sensor per fault codes. O2 sensors code says Lean on both banks i have not changed them yet. My question is when i drive it, cold it runs some what ok, when it gets to the point of warming up the service engine light comes on and it changes the way it runs it boggs down during the transission of no service light on to service light on. Now i go and park it for a minute get back in it the service light is out again and it floods with fuel till the service light comes on. I've check the MAF voltage etc. seems like good connections but still has fault code.

Current codes:
Still says MAF system failure
O2 sensors Lean
Hope i've givin enough info guys!

Thanks

Re: Flooding Problem!!!

Cats plugging up? Fuel pressure regulator stuck closed?

Re: Flooding Problem!!!

A few years ago, I was driving my Jeep Wrangler from CT to MD when all of a sudden the CAT and the exhaust pipe seperated at the welds. The Jeep has two O2 Sensors, 1 before the cat and one after. The noise became horrible from the exhaust, but I kept driving untill the engine would start to bog down. I pulled over and let it cool off for a few minutes and then start it again and it would be fine for a few miles and then bog again. Basically what I'm saying, is that if the O2 sensors are not reading correctly, you will end up with that problem. I would replace both O2's if I were you. I had another problem like that once but that time it was the temp coolant sensor. If your computer is giving fault codes for O2, just replace them.

Re: Flooding Problem!!!

This car has no Cats. It has Headers and 3 in pipes. It does have o2 sensors in the headers, but no air pump pipes, i dont know if that matters!
