I have a 92 3.1 camaro. the car runs like it lack power and also when it idels it always at 1000rpms.also when entering 1st about to release cluth it shakes a bit. any help or suggestions are welcome.

 

also if it helps it has error code 42 and 13. i think 13 is because i removed my cat so now the sensor is just hanging. but like i said any help or suggestion are welcome

 

BUMP

 

Code 42 is an EST fault, which means you're probably running on base time, and the engine really doesn't like that. Check to make sure that the connector that is disconnected to set the ignition timing hasn't pulled apart.
Code 13 means your O2S isn't connected to the ECM. I'd fix that as these engines don't like not knowing the AFR.

 

i dont think i have a o2s because i have no cat and the o2s is just hanging i dunno where to connect it... ill inspect the code 42 but what a cable is not connected is making my car seem sluggish?

 

The connector for the O2S will be hanging out of the wire harness by the top of the bellhousing. Has a single purple wire. And yes, you still have an O2S. It's in the pipe about a foot and a half before the cat.

As for the EST, there will be a black single wire connector with a tan/black wire hanging out of the wiring harness by the ignition coil. Not the gray one with the white wire, that's for the tachometer in the dash, and it's not a weatherpack connector with the green gasket.

 

ok thank ill check up now

 

well the connector is attached and i tried resteting the iac sensor with no luck. when i try to set the rpms to around 500 or even less the car want to turn off but it picks it self. i dunno mayb its timing ??? bad sensor?? can it be a knock sensor cuz i did inspect the block and it showed the connector is dryed out. i prob gonna replace that but anything eles

 

Question is, are you sure you're getting a code 13 and 42? If you were having a problem with the knock sensor, you'd be getting code 43. Codes 14 and 15 are for the coolant temp sensor (check this one especially as it can really throw a wrench in the works if the connector isn't plugged in or if it's damaged internally and open). Code 33 and 34 are MAP, same thing as code 14.

 

Well here is the cable i think that goes to the o2 sensor which i have in order

and here the plug i was talking about that seems dead that i assume that goes into the knock sensor. correct me if i am wrong

Yes on both, and the second one is why the engine is running like garbage. If you need a knock sensor connector, I have one in an envelope ready to go, just need an address.

Also, check your base timing and make sure it's on 10* BTDC.

Well here is an update i have the o2 sensor but the rust infected origanal refuse to come of so i have navel gel and a blow torch to handel that later. i have replaced the pigtail for the knock sensor and nothing really has changed.. i checked my codes again and now and all it states is code 42... when leaving first when about to let go of the clucth the car shakes .. and also still jumps around 2000 rpms when turning on then idels at 1000. any help would nice

o2 sensor has been placed... code 42 still there and still shakes when leaving first a bit... although i have notice it only happens at low rpms or not giving enough gas so .... rpms still idel at 1000 still tring to figure to bring it down. mayb fuel injector stuck or spitting bad....

When doing any work to sensors or any other adjustments. Remember to disconnect the negative battery cable.
With all that your doing you will need to do the reprogram (learn) steps for your ECM

Also check your ICM (idle control motor) Or replace it outright. Clean the housing for it.
make sure that the O ring is good. And the plunger depth is to factory speck 1 1/4 inches
good luck

 

will do ill check that out tonight
