hi
im going to tell you whats wrong and a list of parts ive had replaced
the car is a 2.8 mpfi 85 camaro berlinetta 4speed auto with od and 98,000 kilometers
it has a hesitation problem only sometimes, and when it hesitates the worse i feel the backfire in the intake.
it used to chip the tires when i wanted to get it moving
im getting bad milage, i think it is running rich as it killed my o2 sensor and made my manifolds turn blue and leak
i get 300 kilometers to a full 55 litre tank (about 185 miles?) of highway, a month ago i was getting solid 450 kilometers per tank and i dont keep to the slow lane much.
the car feels less powerful and it downshifts constantly to try and keep speed. when i accellerate it feels like it doesnt have much power until it gets above 4000rpm
when i drive on flat roads i can feel a slight surge like someone is rocking my seat slightly
those are all the symptoms i can think of trhat started a month ago that it didnt used to do. i drove it all winter.
when i got the car last summer 25,000 kms ago i replaced
plugs wire cap rotor
pcv valve
air filter
recently in the past few weeks ive had replaced
coil
starter solonied
air filter
tranny fluid
fuel filter
plugs
cleaned iac
i had the cat cut off to see if it was plugged and it is not.
cleaned engine temp sensor connection
run lots of fuel injection cleaner
i always get the oil changed on time with 5w30
hope i can get some help as its a bugger having my car break every long weekend it seems. i have the next few days off and weas planning to go on a 4000km road trip to visit parents but am not as the car isnt working well.
