2000 Z28/SS

I just bought a 2000 Z28 camaro. From what I can seethe following items have been bolted on; SLP cold air induction, SLP MAF, SLP TB, MDS wires.

EBCM appears to be malfunctioning as ABS INOP, BRAKE, ASC OFF lights come on intermittently, sometimes after it starts, and other times after I run it a bit.

Service engine soon light remains lit, when scanned O2 sensor code P0157 along with knock sensor code P0332 popped up.

Issue with Drivability:

Starting is fine, idling is fine, normal acceleration is ok. When I stab the pedal the power reduces, spuddering and spitting like an old highschool girlfriend. Driving along at 45 mph for instance while in OD, all is good till I want to when I step on it show off and haul *** for a block or so, however, I noticed that if I keep the revs up (like dropping into lower gear manually first) the hesitation frequency is reduced and more often than not gone.

Possible issues that I can think of:

MSD wire(s) bad triggering the knock sensor code

Bad plug(s)

How about the CSS?

Blown Head gasket, however, no white smoke and not consuming coolant I haven't checked for bubbles yet though I will tomorrow.

Any help at would be greatly appreciated. I read through many of the postings here prior to my post, solid answers would be appreciated though i know an exact answer is nearly impossible with out seeing it, especially the EBCM.

First off stabbing the pedal when your car is running like **** will not get you anywhere. You need to check all your plugs and wires. If you don't know how long they have been on there, throw them in the trash, and swap in new ones. When a knock sensor has failed or has detected abnormalities in your engine the car will run like ****. Thats what suppose to happen, knock sensors will pull timing, etc, so the car will run like **** so you wont blow it up until you get it fixed. Another thing you need to do is check your o2 sensors.

Replacing the plugs and wire was the first on the list for sure, however, I just didn't want to start throwing parts at it until it gets fixed. I was hoping that someone has had a similar occurance and found a remedy.

The ignition wires and plugs would triger the knock sensor, would it not?

The O2 sensors, is there a way to test for resistance or continuity before throwing 65 dollar O2 sensors at it? May the plugs and wires clear out both codes?

It could be the EBCM, or it could be something as simple as dirty and/or defective wheel speed sensors. I had the same issues as you but I tried cleaning off the wheel speed sensors and the problem was solved. I would think your engine codes are self-explanatory: there's an issue with both sensors and they probably need to be replaced. At the very least check your wiring and make sure that they are connected properly. Someone please correct me if I'm wrong...

After reading your quote I dont want to work on my car any more, I want to slide in next to mama.

Oh yeah, your post, the wheel sensors being dirty? Did yours have grease on them or just road/brake dust?? Was your failure intermittent as well? or constant?
