It appears the information this unit sends is quite imnportant. Could this really be the cause of all the jumping, missing, backfiring, glowing red hot catalytic, stalling, pissing everyone beyond me off while I slowy accelerate from 0 to 20 in 5.5 MINUTES, and generally making me think my car is about to die crap. One day its 0301, another, 0304, another pick one any one but random? My question is really about the low volts. Does this mean the sensor is recieving low voltage or that it is sending low volts, the language the two use to speak, to the Computer. Since accuracy to hundreths of a volt determines throttle position I also cannot find if my patrticular sensor is adjustable or fixed?

Hello,

Ok, are the codes you posted the only codes you are getting? If so the codes mean.

P0301 - Misfire in cylinder #1

P0304 - Misfire in cylinder #4

FYI - The codes P0301 - P0306 are misfire codes for each cylinder

P0300 - Random or Multiple cylinder misfire.

Now causes for these codes are.

Weak Fuel Pump and/or Fuel Pressure Regulator

Vacuum Leak

Bad Plugs

Bad Plug Wires

Bad Coil

dirty, clogged or inoperative fuel injector

Low cylinder compression

Leaky EGR Valve

Blown Head gasket

The code I am more interested in is0122- TPS Sensor. My plugs, wires- brand new properly gapped and installeed, no gasket or vacuum leaks, egr fine, gas sytem operative, coil testing within limits, head gaskets fairly new and I have no oil or coolant loss, all fuel injectors clean and working. Sorry was tired and frustrated and unclear last night

Ok, when theTPS is bad or going bad the vehicle usually will not run or will start up and run for a few seconds or even maybe a few minutes.

Try the following and post results.

Remove the O2 sensor in the Manifolds and test drive. If all appears normal replace Cat.

I tried removing the O2 sensors, however they would not budge even after ounces of PB Blaster-granted I have never had to use the proper tool and haven't one. I did notice a clanking and saw my exhaust bouncing sounding like a baby rattle, after replacing the TPS-which for 25 bucks I did not mind either way, mind you. After not being able to remove the sensors I beat it with a hammer and think I broke some of it up as I gained some acceleration. All and all, it seems I may have a plugged exhaust system. I am sure you are hoping to hear that your diagnosis was correct and despite my current agreement I will let you know fully tomorrow. If you are correct, this site will be 2 for 2 for me and after my expenses diminshes with this old ass car I will be lighting up your donation page thanks.
