Under_Pressure

This problem started recently I drive a 97 T/A ws6 6MT. Its got a rebuilt motor "355" with about 8k on it. The car feels like it has no power and feels like its going to fall on its face when I give it gas. I notice the mani glowing on the passenger side in the rear. I gutted the drivers cat and removed the passenger 1 thinking that they were cloged but to no aval its still like it was before. I have the following codes All o2's, inuficent cat bank 2, and both CKP codes. The SES light does not flash it just says on.
Heres a link of the orriginal tread on SFFBA.net :

Any help would be greatly appriciated

one or both of your cats are clogged, methinks.

i HAVE NO CATS NOW STILL HAS THE PROBLEM!

Some of the cat has come loose and is clogging the y pipe or exhaust. Pull it all and check for debris.

I got the passenger side cut off before the cat I guess Ill cut off the drivers same place as the other.

Ok today I found out that both sides are glowing both not too red.

is there gas in your oil if the dipstick smells like gas i would suspect injectors.

Check your fuel pressure and see if it's lean. Lean will make um glow quicker than rich.

wouldent bad o2's make me rich?

Not 100% sure about this, but if the computer's thrown codes for all the oxygen sensors, doesn't that mean it's in open loop mode and ignoring the O2 sensor inputs on the assumption they're defective? Fuel pressure is the first thing I'd check, since both manifolds are glowing. Since you mentioned in the original thread that the crank position sensor codes were there before the stumbling/bogging problem started, it could be as simple as a bad fuel pressure regulator. If that's not it, it would be helpful to pull the spark plugs and check them, to make sure of whether or not it's on all cylinders or just a few.

Lean and retarded timing cause glowing headers and stubbling

I'll check fuel pressure on the weekend and change the o2's. hopefully this fixes the problem. Thx for the response guys.

Ok I changed my O2's!!! like always anything thats on the drivers side is easy compared to the passenger . Anyways no more O2 codes but now I got the following: 0174 Fuel trim system lean Bank 2, 0336 Crankshaft Position (CKP) sensor circuit performance and of course 1657 Skip shift/One to four up-shift system control circuit. Now my car is hesitating again in the upper rpms and lower when I give it gas .


As soon as I think I fix it it goes bad again. now what do I do about 0174??? wouldn't the computer compensate for it with the O2 reading? this may be why the mani was glowing it was lean and didn't know it.

Also now the exhaust has a tearing affect to my eyes! I smell and see it now

Rich or lean will make ya cry.

OK Checked fuel pressure today was at the 40psi mark and when I gave it gas 43.

Its getting worse now my car idles at like 500 and shut off on me today while driving around the block.

I also change the ignition module on it and still. now I'm going to disconnect the O2's and see if it runs again. I'm also going to disconnect the MSD box and run it normal. The car feels like its running on 3 cylinders now when it warms up.
