sluggish acceleration
2003 Isuzu Rodeo
fuel filter, plugs, plug wires changed 2 months ago
Verrrry sluggish acceleration..will lose 8-12 mph climbing the small hills here in florida, even with accelerator floored.

diagnostic said 02 sensor heater, random misfire, temp sensor. Transmission checked out ok.

Any suggestions?

RE: sluggish acceleration
I don't suppose you have actual Code NUMBERS? Without them I would guess fuel pump or restricted exhaust. Look at the catalatic converter after a few miles. If it's glowing the exhaust is plugged. Rotten egg smell is also a giveaway of a clogged exhaust.

No, they didn't give me the actual code #.....they want me to give them $170 for "further diagnostics" .

The vehicle is significantly louder when accelerating....i will check into the catalatic converter.
Thank you.

RE: sluggish acceleration
Now there is another possible "hint" toward the problem. Loud exhaust would tend to mean a leak. Exhaust leaks can set Oxygen Sensor codes but usually not the Heater code. (That's where the actual numbers help.) There is also the possibility that an Oxygen sensor has been broken off or torn out causing the leak and the code.

Please keep us posted.
Thanks, Garner
