my car is being major PITA this week... little help

[CincinnatiKid]

I'm glad this thread is your twitter now.

Its those fucking muffler bearings dude. They wear out and get hot and trasfer heat up the exhaust pipe to the block thus heat saturating your block and making your temp sensor go nuts.

[ubernasty]

hah.. wow i sounded like a emo bitch last night.

sorry bout that fellas

edit: delete thread?

Really?

I was mostly just curious why the gauge jumps around. I figured the o2 is what's causing the problem tho.

Alright well i'm off to the bar to drink away my problems, maybe if i get drunk enough my car will be good by the morning hah.

it probably jumps around because your car has air in the cooling system. you lose power because the coolant sensor is a primary source for calculating the amount of fuel to be injected. the O2 is just a minor correction factor, for the most part.

fuck. nevermind. its a ground.... i just wanna have it connected to the oem location cus i'm ocd like that.

it bolts to the drivers frame rail..

why would there be air in my coolant system after the oil pan got changed.. it was fine before.

I think that they are 2 diff sensors...one sensor for motronic the other for the temp guage

Alright, i just hooked the ground back up and now it won't even run? It'll start with some throttle rev to 3k then fall back down and stall.

Oh and it smells like fuel strong.

I think you're doing it wrong. You should probably pay to let some hacks do work to your car, you're no better!

Did you connect the positive cable to ground? ;)

I've ben drinking and I'm joking, but for srs bsns, why did you even need to change the oil pan? If all you did was change the oil pan (or the shop did, whatever), I don't see why you're having these problems. And if you were in Cali I'd drive to you and help figure this out.

So everything wrked fine before changing the oil pan? And that's all the "shop" did? Did they say how they did it?

I said fan clutch, because unless I'm misreading, the car is doing fine on the highway, but not so good around town.

Shut the fuck up.

They didn't say how they did it. I needed to change the pan cus it was on pieces far from my house. I would have done it myself but didn't want to take the risk, for my own safety, of changing it with jack stands and shit on the side of the road. I don't know why the fuck its not running now.

No its just not so good all around. Won't even idle now.

[ubernasty]

BUMP this up.

Car starts no problem now, but it just revs to 3-4k then drops and stalls. There is a strong fuel odor.

After some research it could maybe by a relay. Would driving on a disconnected ground from oil pan to frame rail for 20 miles cause a relay to fail?

[ubernasty]

This the problem for the symptoms?? 3 relays next to power steering res look fried...

[blocke]

Since we have already established that the shop that did the work was a bunch of fuckups..it might be time to start checking other unrelated components and connections they may have fucked up along the way.

-Is your AFM plug secure?
-No vac leaks?
-Pull the vac line from the FPR..see if its dry. Fuel in there means the FPR is bad/leaking.
-Investigate fuel odor. are injectors leaking? Engine just flooding?
-Reset DME and see if the reving at start thing persist.

I had issues with my oil pan ground strap for a while. So for good measure, I went to auto parts store and bought 2 long ground cables for 7 bucks. Attached one from the strut tower to the intake manny, and the other from the alternator bracket to the chassis. This smoothed out my idle, and helped starting. Worth a try.
