????95camaro HELP!!!

I have a problem with my car .... well a few of them actually
1. my temp gauge goes crazy. Sometimes i cant even get four blocks with out it hitting 260.. but it should not even be warmed up yet?? if i turn on the heater to cool it down it blows Ice cold air.. when it starts to blow warm air the temp will drop... it dose this almost every time i drive it.. right now it is cold outside so i dont think its really overheating.. idont know it is weird..... please help if you have any ideas.. (i have already replaced my thermostat
2. my second problem is when i drve at like 45 50 or 55 it jumps .. almost like it is missing but i dont think it is..


*** any help would be greatly appreicated**** thanks

your car jumps or your speedo cluster jumps?

you can feel it jump or sputter i dont really know how to describe it but you can also see it on the rpm gauge and the speedometer

for your temp problem i would first replace the thermostat and for your 2nd problem i would have the car scaned for codes (at either a dealership or autozone, autozone does it for free) after you get the codes it will more than likely will tell you what could be causing your sputtering

I took my car to an auto zone already and it wouldnt read any codes off of my car, he said that there is some electrical chip in cars like mine that block the scanner from picking up any codes.. I guess ill have to take it to a dealer...

I already replaced my thermostat.. unless there is more than one... is there? Im not very car savy!

also when your temp gauge says 260 does the car smell hot? if you were to open the hood would it be a lot more hot than usual? btw does your car have a v8 or v6?

For the jumping or the sputtering might it be the fuel injectors or mabe even the fuel filter?

oh wait you have a 95.... thats right.... i used to have the same problem when scanning codes.... you need a special adapter for just that year....and no their is only one thermostat.....but make sure that you bled the lines of any air that possibly got into the lines when installing the thermostat...

v-6 no sometimes i dont think it is hot... the temp changes so fast that i dont think it is possible.. like with in 10 seconds it can go from185 to260 and back down again

how would i have bled the lines ?? i dont know if i did cause im not familiar with all the terms..

sounds like a sensor malfunctioning or an electical problem... im not the guy to talk about as far as that.... atleast that should cost you less than if your car was actualy overheating...

i'm not totaly sure on a v6, but on an LT1 V8 their are 2 bleeders http://shbox.com/1/bleeders.jpg that will show you what to look for -Idle the engine and monitor the temp. If the temp goes abnormally high, you may have an air pocket. Open the bleeder screws after the thermostat is open to remove any air. Only a stream of coolant will come out when all air is gone and there will be no spitting or hissing.
Close screws and monitor the temp.
this link will give you more information about your cooling system and sensors involved http://shbox.com/1/4th_gen_tech2.html#cooling

yeah.. i hope so.. thanks for all of your help any ways....... but about bleeding the lines? how is that done

thanks for your help!

*** any help would be greatly appreicated**** thanksNo you're not overheating. You have a loose connection in the temperature gage circuit. This is a technically easy problem. However if the bad connection/part is behind the dash it's time consuming to repair. So lets start the easy half. Make sure you have a good connection under the hood at the temperature sensor. It is located on the left side of the engine block. .§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§REFUSE . TO . LOSE§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§

thanks Ill look in to that!

the temperature guage could also be failing and need to be replaced. this may also explaine the sputtering, as the engine runs according to its temperature, so if the temperature is incorrect the air fule mixture will be effected and so will how the car runs.

that jumping happend 2 me it was my maf sensor i think but im sure it was that

all of your suggestions really do help! I am trying your ideas, Any other ideas are more than welcome... thanks again....

it is not my MAF sensor.. already checked...? what do I try next?????

The reading on the temp gauge itself shouldnt have anything to do with engine operations.. Doesnt the temp gauge, and the ECU each have their own temp sensors? Correct me if im wrong, not familiar with newer models

the tempature dosent have anything to do with jumping... the temp is fine when it dose the weird jumpy thing.... it overheating was a seperate problem.. but i think that one is fixed now!!... now just to solve the jumping problem..


thanks again for the help

have you checked/replaced the gauge temp sensor, and the harness/wiring at the temp sensor??
Thats where I would start

as far as the temp sensor, in newer cars i believe there is only the one. The PCM sends the temp signal to the guage cluster if i am correct. but i may be mistaken. but seeing as that problem is possibly fixed, ill look at the jumping.

When you say jumping what are the RPM's doing? is it like its dropping in and out of overdrive? going up and down by a few hundred rpm each time? If so it sounds like a bad lockup converter solenoid. I had heard of a problem in third gens, that had this problem but it was due to another issue. It turns out in third gens there is a condition where the virbrations of the cooling fans sound like engine knock to the knock sensor, and it retards the timing, which lowers the engine rpm, which causes the converter to unlock, when this happens the vibration changes, and the knock sensor restores timing, causing the engine to resume normal operation, and it locks up again, creating the harmonic vibration again, which starts the cycle all over again. It is possible that this is happening to your car. The only thing i can think of is to change your knock sensor, or change your cooling fan, and hope for the best. My 89 RS was doing this, i replaced the cooling fan motor (as it burned out anyway) and the problem went away. Your problem may be similar, or it could be some other electrical problem.

NO.. it dosent drop and rise a few hundred rpms.. its less than that .. but i thnk my car is a fourth gen... 95.. i dunno...

ok definatly sounds like the converter locking and unlocking. this is a locking solenoid problem. either you have a solinoid problem, or a signal problem. I would take it to the dealership and have a transmission speciallist diagnose and repair this one.

Mine seems to be acting funny , the transmission anyways. I don't know if it's just old fluid or if it's time for another rebuild..I beat the living hell out of the 700r4. It seems like it slips or doesn't fully engage sometimes when it's like under 60F outside. I had a buddy of mine look at it that works at Tanner Transmissions but he said it seemed fine. I had no metal flakes or anything in the pan or filter , no clay like material from the belts grinding into dust and creating clogs , none of that. Is it maybe my tranny fluid is too cold ? I also put a fluid cooler on it with a little 10" fan.

could be, you could wire a switch in line to the tranny cooling fan to turn it off in cold weather to allow the tranny fluid to come up to temp.
