The cat convertor on my 96 s-10 2.2l is gone im looking at replacing it soon. Would this cause my truck to have lack of power?

A blocked exhaust for whatever reason can cause low power. Do a compression test on your cylinders. Check out these guides

and

Please run down these guides and report back.

Hi chevy5196 and welcome to 2carpros

Do a fuel pressure test to confirm that the fuel pump is producing the correct fuel pressure. If okay check and test the idle air control valve/throttle position sensor/MAF/MAP sensors-then report back for more assistance

Good Luck

Good afternoon,

Some possible issues.

1. Fuel pressure. you need to verify correct fuel pressure.

https://www.2carpros.com/articles/how-to-check-fuel-system-pressure-and-regulator

2. Catalytic converter clogged. you need to check the back pressure of the exhaust.

https://www.2carpros.com/articles/how-to-test-a-catalytic-converter

3. Throttle body. Check the throttle body plate for any carbon build up.

https://www.2carpros.com/articles/throttle-actuator-service

4. Valve timing. I assume it is a 2.5, not a 2.3. The timing chain needs to be checked to be sure it is not worn.

V6 vortec. Its only throwing p0420 code. But only after hollowing out my converter. It was misfiring/bogging down before I did it too and throwing no code, which is why I hollowed out the converter thinking it was clogged up, but that did nothing either, so now its throwing the code and still occuring. Took it to a local shop they said to replace the cap and button and it should fix it, it seems to stop the misfiring and bogging down for about 4-5 days and was running perfect, so I thought it was the problem. But now its doing it yet again running like ass. Seems to only occur when pressing throttle through first and second gear (in auto trans) once I get it to third shift(gear) it smooths out and runs ok with very little to no bog down. Seems I have to ease the throttle to get it to not do it, but its when I press hard on the pedal it doesnt want to go, or if it does bogs down and sputters. Hope this info is a little more helpful. Thank you.

Oh also to mention the local shop smoked it out (vaccum) and checked my fuel preassure and those all tested out fine. For some reason im thinkin it could now be injectors not fuelling correctly/clogged, or maybe fuel pump not pumping the right amount of fuel into the engine when I press on the gas pedal? Not sure what it could be though. Also tried sea foam but that did absolutely nothing either.

Did you use good quality ignition parts? Auto store house brand is crap generally. So that has spider/poppet injection?

It looks fine I even checked inside to see if gunk was built up in the connectors. I have tried everything mechanics have reccommended and still no fix for it. It also seems like it ran better for about a week after I put the new plugs in too, but started up doing it again. I used ac delco parts, except for the plug wires, they were like in a black box with purple at the top.

It seems that my truck has lost power. And a great deal of fuel economy. I have replaced the cap, rotor, plugs, wires, fuel filter and even the catalytic converter. But none of these have really helped all that much. Could this be the injectors? Or maybee the fuel pump?

If your service engine light is on then you should have the engine scanned, most auto parts stores do this. Check your fuel pressure it should be 60-66 p.S.I. It could be the injector lines inside the intake manifold that are cracked causing this as well. A pro should check that out as he will have more experieince on this.

Was running good then suddenly started acting up as I left a stop sign. Idles fine, revs up good when parked. Runs very rough through all gears. Plugs all black soot. Replaced coil pack, plugs and wires, fuel filter, injectors, fpr, fuel pump six months ago, checked TPS was okay. Small amount of black smoke when revved up. Very rough at any rpm under load.
