what sensor is this?

[engineblock]

I was wondering what sensor is this that i have in front of the transmission, i thought it was the speed sensor but i think i was mistaken. Can someone please tell me what i is? (its the yellow piece), mysymptoms are when im idling at a stop my car starts to jerk like the engine is trying to come out. I own 96 eclipse rs and i know that the 4 cylinder avengers have the same engine as mine (420a) so anybody please help

the input/output speed sensors won't cause jerking at idle ...

[engineblock]

will placing the intake manifold gasket wrong cause jerking at idle.

ya think? like prob have huge vaccume leak

[bad venge]

any leak will cause unmetered air to get in and throw off the air fuel ratio and cause stumbling

So does everyone agree??

I plan on driving my avenger for a while (hell, i just got it!)

so instead of doing a head gasket/valve/oil ring job or whatevers going on should i just replace the motor with a new one?

which it is 4cylinder 2.0 if the gas mileage will still be good i wanna drop a v6 3.0 in it.

i love my car damnit. but i dont wanna spend 2,000 or something to fix a motor that will just have problems down the line.

The 2.0 to the 3.0 swap would be a hard one

[circumventor]
