can some1 please help me i have a 91 camaro z28 convertible 305 auto and if im doing around 35 and floor it my engine starts poppng alot sounds kinda like water boiling lol well its not really funny but you get my point anybody else ever have this problem

 

Have you "investigated" anything, yet...?
Last tune up (plugs, wires, distributor cap, rotor, coil, fuel filters, air filters, transmission tune up)?
Checked for vacuum leaks, wires against exhaust?
How many miles on the engine...catalytic converters?
Can you check for fuel pressure during WOT (wide open throttle)?

Eliminate the simple solutions 1st

 

im going to do a complete tune up next week it has 70,000 miles on it

 

Just went through this on my 91 bird, Change the coolant temp sensor, they only cost $10 or less.

 

did your car run perfectly normal until you floored it then it started popping and didnt go any where

 

Yep pretty much. If I went beyond 1/2 throttle it would stumble and not pick up also it had a poping noise in the engine that would sometimes make it to the exhaust.

 

My engine would make a backfiring noise when i would floor it too. My problem was that the cam had went bad.

 

How about a clogged catalytic converter. When they go bad and expand and contract they make a popping sound. The engine also boggs too.

 

be quit i dont want to hear that
that popping sound also comes out of my pipes and when your cat is clogged doesnt it usually stink real bad or not and thank you guys so far im going to check all these things

 

Not all the time does a bad cat stink. Its just something to look into too. It would explain the loss of power. A compression check and a leak down test maybe a good place to start. The compression test could help rule out a bad cam burnt/cracked valve.

 

could you please explain how to test compression
