Thats not good. It is the MAP sensor and critical to engine operation. I would replace it. Funny normally the two retaining prongs break and not the MAP sensor. What condition is the orange accordian seal in?

The seal looks to be in very good shape. I'll have to look around and see what a new MAP sensor is going to run me. *sigh* I'm saving so much money doing things myself.

Oh well, this is how you learn.

Will it be safe to drive my car a couple miles to the local AZ to pick up a sensor? How about if they don't have it? Safe to drive 26 hwy miles round trip to work and back?

You should be able to drive it a short distance with no problems, other than it driving like crap. The AC-DElco part # is 213-796 for reference. I believe A-Z carries Wells, part# SU1078. Wells isn't abad brand, but it's been my experience to stick with OEM parts when it comes to critical components. Also, be careful re-installing it. The bottom nipple is off-centered, so if you try to put it on wrong, you'll break the little plastic retainer clips as bnaylor mentioned earlier.

I went with the Wells brand as it was all I could find nearby. The car runs as bad with the new MAP sensor on as it did the old one. Lots of chugging and misfires. I made it through changing 4 of my 6 plugs last night before I was overcome with exaustion (4am) and took those out and double checked the gaps just a minute ago. No help. Would only having 4 plugs done affect the car? I did break one of the clips on the connector for the MAP sensor despite my best efforts to be careful. The sensor still seems securely attached though, so I cannot believe this is related. Any ideas?

Incidentally, there was a crack in the ceramic of the number 3 plug that I had replaced previously. It was tiny in width (just some black spiderweb cracks really) but ran for over an inch, so I suspect that was what was causing my original issue.

One final question: Do the metal boot shields serve any neccesary purpose? I only ask because it's all but imposible to get my number 6 plug seated with the metal shield in place.

The heat shields isolate the boots from heat, so they do serve a purpose. If the other two plugs are bad, then changing the other 4 would do no good. Have you changed the wires as well, and if so, what brand did you install? Also, have A-Z clear the CEL code for the MAP sensor now that you have it changed.

never mind

Alright, I'm a certifiable dumb-ass. I crossed the 3 and 5 wires. Once those were in the correct position the car runs flawlessly. I drove it about 5 miles total with the wires crossed. Hopefully I didn't do too much damage to the engine. Thanks for all your help guys. It's nice to be able to punch it and not have the car bog down.

I doubt there was any engine damage. We have been all through the school of hard knocks so I wouldn't worry about it. Important thing is you got it fixed and we are glad to hear about that.

richtazz · #25 09-28-2006, 06:11 AM

I'm with bnaylor, we've all done something silly like that to frustrate ourselves. We like hearing happy endings, glad you got her fixed.

Heres a tip from the spark plug wire changing master. lol. when your doing wires to make it so you dont cross wires. do either one wire at a time or if you have to take them all off the best way to do it is to take some masking tape put it around the wire and number each wire to the correct cylinder. this is very helpful

on my trans am LT1 if you install headers the wires tend to rest on the headers so you go through wires all the time. unfortunately i didnt know this till after the 5 hour install job. so i just wrap the wires in plug booties.
