Rebuilt engine head (Cams, lifter's, etc.)
New TPS (Throttle position sensor)
New idle air control
New timing belt
New exhaust manifold (Old one was cracked)
New Wires (Plugs/wires)
I have recently ordered a new fuel pump and 4 re-manufactured fuel injector's. Plan to switch them all into the car as soon as I get it all. Am hoping it increases the car's power if even a little.
Now what I mean by power is if I were to drive my brother's Mitsubishi eclipse with the identical same engine, its got so much more takeoff power and just overall power when full throttling it. Now hop into my car and it doesn't compare at all. The only difference is my brother's car has performance exhaust system and a different computer type, that's it.
I've just started blindly replacing parts in hopes of finding why its missing power. I have had my friend and my brother both drive my car and they both say its definitely missing power and somethings not right.
I really don't know what else to try at this point, im just blindly throwing money around. I do believe the wiring for the Throttle position sensor is faulty and needs to be clipped and rewired or something as my brother put it. It apparently connects/disconnects if its wiggling around too much, however I don't believe it would be causing this power issue to this extent.
Also not sure if its worth mentioning but it backfires just a little bit when just rolling and not pressing gas (Like if im at 4k rpm and stop giving it gas, as its slowly coming back down it sometimes backfires a little). Not nearly as much since I replaced the exhaust manifold, but still does a little.
What are your suggestions on what I could try doing next or what you think it could be?
have the same problem?
