I have replaced everythang . OPTI , PLUGS & WIRES, MAP sensor, tps sensor , o2 sensors. It still randomly spudders and back fires out of the intake. It also has poor throttle response. But its not all the time. It seems to happen more when it gets hot too. All the car burns alot of oil. And the intake it coated with it. Atleast a quart every fill up. Why do you think that is? What else do you think it could be ? Leaky injectors? Clogged injectors? Bad fuel pump? Thanks for any help you can give me!

You need to do a leakdown test. It sounds like oil is getting into the combustion chambers, fouling plugs, making your car backfire, etc etc.

 

Ya thats what i was kinda thinking. But I don't know how to do a leak down test.
