Ready to Push it Off a Cliff!

Does this thing have an egr or no?

[GhostDakota]

Thanks fella's. A guy was recommending crank and cam position sensors. He said his car did the exact thing mine is doing right now. I may buy a Walker Y pipe through work just to get rid of the supposed bad cat, and also do those two sensors?

Is there any way for me to test the crank and cam sensors?

I cleaned up the ECU connections on the remanned ECU, and will clean up the harness connections on the car and try the reman again.

EGR are the two tubes coming off the exhaust manifold, right? If so, it does have them.

[JL8Jeff]

The EGR is only on the passenger side up on the front of the engine going into the front of the exhaust manifold, the AIR tubes are on both sides and have the check valves. The check valves can go bad (and often do). The air should only be able to go into the manifold and not come back through.

[GhostDakota]

Thanks, Jeff. FWIW: I ordered the Walker OR-Y through my work. It should be here within 1-2 weeks.

New Walker Y-Installed. Still running like ass:




Driver side:


Pass. side:


Driver side pipe is this short:


Had to weld in some pipe:

[GhostDakota]

I took the car to a local Performance shop that does tuning. He hooked it up to his laptop, fired it up and ran his programs. He said it's running lean (though smells of unburnt fuel). It's missing on 5, 7, and also on 6, 8. More-so on 5, 7. Driver side front o2 is bad. I have a new one that I will be installing to see what it does. Hopefuly is resolves some of the issues, if not everything. I may change the plugs again as well since these brand new ones may be fouled...

[GhostDakota]

I replaced the front driver side o2, recet ECU. Runs better, not the fix though. It has some weird electrical things going on. Shifted into reverse and the speedo jumped to 20 MPH. Opened the cutout and the RPM's jumped 300 RPM. 2 weeks ago the speedo was reading WAY low. 42 MPH when doing 70 for example.

[GhostDakota]

Just wanted to update the latest. My buddy and I at work checked the wires running from the PCM to the coils. They all have continuity per our multi-meter. So, the wires are good from the PCM to the coils. One more thing ruled out I guess....

could have continuity but doesnt rule out it being shorted.

i think youre best bet is to rewire all the coils.

[GhostDakota]

I finally threw in the towel. I just dropped it off at a local shop this morning. We'll see what they fine.

[GhostDakota]

I'll do some more looking and a compression test soon.

I dropped it off at another local shop today. They put some time into it and are going to put some more work into it next week.

Just some info from my Torque app...

End of report.

41* timing advance?!

i thought you pushed it off a cliff or drove threw a river and got stuck

[sweetbmxrider]

Bring the engine up to 3-3500 and see what the short term fuel trims do.

I'll do that next. Here's what I have at the moment...

What have I been saying?

[grazi]

I would just unload it for cheap so you don't have to deal with it anymore. PM Me........

[stealth355tpi]

Didn't read through everything but if the wiring all looks good, how about the computer? My 98 had some weird problems but somehow once I grounded the computer everything worked fine.

You should read through everything.

[WSex]

ghostdakota, compression test is pointless imo. is say swap the harness. if anything you can resell the harness.
have the people youve taken the car too used an oscilloscope?

How is a compression test pointless?

Sounds like your car is wired like hell if your cutout is messing up dash cluster signals..

I read the whole thread, and could not figure out what you have been saying.

[GhostDakota]

I did state earlier that I swapped ECU's from my buddies '98 Camaro SS. Didn't change anything.

So if you're just reading this, #5 and #7 are the misfiring cylinders.

I purchased a compression tester today:


Only had time to do 4 cylinders, but everything checked out fine:


And the plugs ... 1-3-5-7:

you swapped the ecu but not the harness itself

ok i know you have tried different coils. but heres something you should try.
undo the brackets for the coils and swap sides. plug it in and start it to make sure its not the wiring that is on the bracket.
if the misfire is still on 5 and 7 then we can definitely rule out the coils and wiring that is on the coil brackets.


and again have you hooked up an oscilloscope?
