About a month or so ago, I was having minor problems with sluggish acceleration and occasional surging.My ecu was reading 21 and 33(?). In an attempt to repair any possible culprits, I changed the 02 sensor, the PCV valve, and the cap and rotor. Because the car was running rich, I adjusted the timing a little in advance.
For whatever reason, my performance problems have actually increased. VERY sluggish!!!
It seems to run much better before it warms up so I am unsure what components I should begin with. I thought about the fuel pump, but since it is running rich, I think the problem lies elsewhere. I'm still getting readings for the ignition circuit and the 02 sensor.
Also, my A/C has started acting up. The light always comes on but the unit doesn't always engage. Sometimes it engages and still doens't blow cold air; sometimes it does.
I NEED SOME SERIOUS HELP!!!
