Misfire video's of the '95

[Cl-Slick]

The car is still acting up after a top 60k, swapped out cam sensor, coil pack, and DIS. It's sputtering under acceleration, backfiring occasionally, and just running like crap. Here are the videos I took tonight, maybe they can help show what I'm talking about better.

Pull the plugs on 5 and 6 and see if you guys fouled them out when the wires were crossed.

Ok, looks like a project for next weekend. Tomorrow I'm going to take a pic of the EGR part I need to replace. I doubt that's causing it to run that poorly though. I want to have this thing ready for Nashville!

He just called me and said the car is fixed now. After sitting overnight and then taking it for a drive, the idle has smoothed out, and he said the car has much more power than it's ever had while he's owned it--even squealed tires off the line.

Maybe the computer reset itself after the plug wires were corrected and the car was driven awhile to burn out any carb cleaner and other crap used to clean out the intake.

It did have oil in the plug wells previously; thus the reason we did a top 60. Either way, as of right now the car appears to run great according to him. I've noticed that any time I've torn into my cars, sometimes it can take a day or 2 and a little driving to get it to where it seems to run correctly anyway.

With new plugs, valve cover gaskets, MAF, and O2 sensors, the car's power appears to be fully restored. Now we'll see what kind of mpg he's getting.

Oh yeah, now put a catted Y on there; that exhaust sounds awful. Plus we got nasty looks from the neighbors yesterday.

Nevermind....calls back again while driving the car to work and it's doing the same thing, stumbling, backfiring, etc.

We're at a loss. The only thing we havent replaced is plug wires. CEL is only showing a 332, and he did have a couple of those thin plastic EGR lines that were broken or needed replacing. Would the EGR cause the car to run horribly like this?

I wish he could just rip the EGR system off and throw it in the trash. What a garbage system on these cars. My 89 MTX has it b/c it's a CA car and it's another PITA thing to worry with.

I told him to run a cylinder balance test. We did the KOEO and KOER tests. I can have him check to see if we fouled up the plugs, but I don't know what else to check. These cars aren't that complicated; there can only be so many things that would cause this.

If you haven't replaced the vacuum lines, it'll run crappy. Also, if there was oil in the plug wells there's a good chance the old wires are arcing out and causing a misfire. I'd replace 'em.

Thanks. We'll probably just go ahead and replace the wires. The EGR lines that were broken were not the rubber ones, but ones "made out of WD-40 straw material" as my brother said, lmao. Very flimsy, cheapy, worthless looking things.

 

[Bob Gervais]

Yep, those are vacuum lines. The other ones are for the DPFE. Hopefully, Colby's Mighty Puttying some WD40 straws together....

 

[Cl-Slick]

Going to buy some new wires this weekend. I still need to post a WTB for new EGR vaccuum lines, I'm out of straws.

 

[Bob Gervais]

You can use regular vacuum line for that if you want to. Take the rubber elbow to the parts store, get the same size ID vacuum hose, cut to the length you need.

Why didnt you replace the wires if you were going thru all the trouble to do gaskets and plugs?

Thats like replacing the CPS and not touching the water pump.

 

[Bob Gervais]

Because beancounter?

Because I went full retard.

 

[Cl-Slick]

Can someone post a pic of where both of those EGR hoses go on the intake? Going to try & fix that tomorrow before I have to go to work.

Upon further inspection the car runs fine until it gets warm, then it starts misfiring and running ruff. Still guessing its plug wires.

UPDATE! Car is fixed, new wires did the trick!
