Well i think i will have to send my car to the dealership because of this weird issue i am having. Since there is no harm in posting, i thought ill try posting my issue here and maybe someone (with a similar issue) could help me solve it.
I've just bought my 2001 Eclipse GS.
Before buying the car it ran fine without any problems, after buying it its had this problem that to this day i can't solve my self.
If i drive the car nice and slow with very slow acceleration the car runs perfect but the minute i gun it (floor the gas paddle) it sputters like hell. Meaning if press the gas paddle hard it it feels like someone is holding the car back but if i slowly accelerate it accelerates fine. To this point i have tired replacing the spark plug wires and the spark plugs with oem parts to no avail.
any suggestions what i can do and or check before sending it to the dealer?
ps. i have used numerous fuel injector cleaner, intake manifold cleaner with little to no effect. i did notice that about 2 weeks after replacing the plugs that they were pretty dirty (black)
