Camaro :: 96 Chevy High Temp At Idle About 230 - 240
Oct 19, 2009
96 chevy camaro 3.8. i got a problem with the idle temperature, just replaced the water pump and thermostat (180 degree). when driving around the cars stays at a constant 180 temp but when sitting and idling for more than 3 or 4 minutes the temp starts to climb and gets up to about 230-240 which i know is not good but that's when the fans start to kick on. The system is clean all new antifreeze, no air in the system every thing ready to go. I know its not normal for the temp to climb that high, what else could be cause this high temp at idle?

I have a 1993 Chevy Camaro z28 5.7 with about 135,000 miles. It made a whining/humming noise recently. It sounded soft at first, added oil the. Noise would go away. One time it got REALLY loud, spooked my girlfriend as well as me, then it stalled out and died. I checked the oil but that was fine so it bothere me even more. So I Let it sit for a few minutes then started with no problem. It happened again recently but i slowed down an it gt really loud again. Let it rest then tried going home. I was going about 75 miles per hour until it didn't want to give gas and started to stall. I pulled over and shut it off for a bit them drove it home while it did that stalling out about twice more.

The car is a 91 Chevy Camaro RS , 3.1 V6 and a 5 speed. Mileage is approx 400K + , the odometer has never worked since purchase and showed 239K when I purchased it approx 8 years ago.
The battery croaked due to being low on water and at the same time a stalling problem began so I wonder if the battery going bad may have contributed to the stalling issue.
The battery has been replaced with a new one but the stalling issue has not been resolved by replacing the battery.
At start up the car will idle correctly, occasionally when starting the rpm's will shoot up then slowly slow to correct idle
speed and usually continue to run.
When driving car seems fine but when the clutch is pushed in when coming to a stop at a sign, light, etc the engine rpm's begin to slow from traveling r's down to what would be normal idle speed, this is when it stalls.
If I left foot the brake and keep r's up with my right foot I can prevent the car from stalling. If I (using my foot on the gas) allow the r's to slowly come down to sitting idle speed it usually will not stall.
The cat converter was removed from the car several years back so it's not a clogged exhaust problem.

My 1995 chevy camaro has been overheating. at first i thought it was the thermostat sticking because there was no spewing or smoking so i changed the thermostat and my car was still over heating. I finally found out that the water pump was leaking fluids. so I changed out the water pump and filled it full of coolant. i turned on my car and within 10 minutes the gauge went up to 260 degrees and went down a little bit but stayed around 260, there was no spewing or leaking or smoking again. I was thinking that maybe now it could be the sensor but im not sure.

Yesterday when I started my car the coolant temp was near 100 (from a previous drive several hours prior) and it was over 80 degrees outside, yet the car went into high idle mode as though it was cold outside. It does this sometimes, but not always, and if I dont let it idle down and just start driving, it'll stay in high idle for a long time (i.e. even after a couple miles of driving, if I put it in neutral it'll rev back up to high idle).
Air temp sensor and coolant temp sensor are working properly, but it doesn't seem like a normal thing to do, but its done it for years. Anything else that might cause it, or any way to stop it?

I have a code for iat sensor 1 circuit high. It's the only code I can pull. I replaced the sensor in the manifold and still no change. The truck revs up when started but kinda finds its idle rpm after a second and the idle fluctuates some when the truck is warmed up too. I have a snap on solus and all parameters seem to be good. Icp sensor is also new thinking it might be the cause. Other than that the truck runs perfect and doesn't miss a beat.

I have a 2000 z28 Camaro, and I'm having problems with it slipping at high speed. and I noticed today that fluid is leaking and the car loses power as it warms up. it runs great starts right up, just having problems with the tranny. What may be going on, I do check the fluid and fill it when it needs it. and it runs great until I need to get up to around 50mph.

I have a 96 Camaro that is rough when idling. However it isnt always rough sometimes I start it up and it will run great but other times it is very rough but only while idling. When I drive it and i starts rough I just turn it off and back on again and usually it will run fine the second or third time I do this. I have already ran a couple cans of Seafoam through it.

Ok so I recently started noticing my car was overheating and the sensor would go off saying coolant temp hot. So I started by adding coolant that didn't work. I than replaced the thermostat didn't change. I saw the water pump was leaking and changed that but before I did I was driving it home one night and the engine stopped and I barely had control of the car. Now the water pump is new and I don't know what the problem is. I think it's the head gasket ???

So yesterday my truck decided to start giving me fits right after it finally got extra cold and snowy here! I noticed early on this fall that my water pump was leaking, so I replaced it. I also found that my truck only blew hot air while in motion, and cold air while it was stopped or at idle. At this point I replaced the thermostat and housing. I originally had the stock setup with the combined thermostat and housing. The new one is and updated GM version with the separate thermostat and housing assembly. Everything seemed to be ok until yesterday morning.
This is where my problem is now. Yesterday on my way to work, the message center said my coolant was too hot. The temp gauge showed the truck at about 250 degrees. My speed was only about 45mph and it was 6 degrees outside. I ended up parking the truck and looking at it after work. I found it was still doing the exact same thing. When I investigated further, I found that the upper radiator hose was hot, while the lower one coming out of the thermostat housing was cold.
At this point I figured that I had a bad thermostat, and bought a replacement. I tested the old one on my stove top in a pan of water and found that it did actually open at about 175 degrees, so I'm not so sure it was bad now. With the new thermostat installed, the engine is no longer overheating and the temp stays around 235 while driving. However, I am back to the heater blowing cold air at idle and while stopped, and warm air while driving. In addition, the rear heater now only blows cold air, it never warms up.

I have 2002 Chevy suburban. Recently, a high pitch whine has developed. When accelerating the whine intensifies. I replaced the alternator ... No change! What could it be? Speedometer cable?

My dad's 1996 Chevy Silverado will not shift into hi gear. The truck starts up fine and he can drive it but for some reason it won't shift into hi gear. Him and I are clueless as to why it won't. He has a 1996 Chevy Silverado, 6.5 liter V-8 automatic transmission, and its a diesel. We really want to fix the truck ourselves so we are trying to avoid taking it to a shop.

I have a 96 chevy Silverado 4x4 5.7 motor and it does the same thing but it doesn't leave in first gear, it misfires and high rpms and doesn't go in overdrive. but if I drive a little while and turn it off, it's fine it acts like a normal truck would. then if my truck is off for more that a couple of hours it goes back to it acting up.

01 2500hd, 8.1L allison auto, push button 4x4. wont lock in until its about 2000 rpm then will release just fine. Just not sure of where to start looking for the problem. Actuator on the axle or in the transfer case or something else?

1983 chevy c10I bought this old truck about a week ago and I noticed a few things right from the start. Engine revs kind of high before the transmission engages (about 1,200+ rpms).at highway speed the truck shakes and vibrates really bad at times. the steering wheel doesn't vibrate so I dont think it`s ball joints or tie rods.The truck barely goes backwards when in reverse, the engine revs high (over 2000 rpm) but the truck barely moves backwards.It almost feels like the emergency brake is on.
yesterday the truck (transmission?) started slipping and then it stopped working. I was stopped on the side of the road and this old guy stopped.I told him what happened and he said it was probably the transmission but he knew a way to get it working again long enough to get me home. He picked up a handful of sand from the side of the road and put it in the transmission dip stick hole and then poured half a bottle of brake fluid in.He said the transmission is gone anyway so the sand and brake fluid wont do it any more harm.The truck ran again but not far enough to get me home I had to get it towed. Now I am wondering if it really was the transmission and not just the torque converter. I guess it doesn't matter now because the transmission is probably toast now.

I have a 92 chevy pick up 5.7 with 159,000 miles. The truck runs and starts great but shortly after I bought it 3 years ago it developed a sort of misfire at higher rpm's, it's fine if I drive it normally but if I try to pass someone it will downshift then fall on it's face, (spit,sputter and slow down). some times I can feather the accelerator and it will come back again. I normally don't drive the truck in the winter but this week I was forced to use it and the cold weather is seriously affecting it, it took forever to get it up to 70 mph after getting on the highway. once up to speed it will do 75 all day without an issue.
I've replaced the plugs, wires, pulled the throttle body and cleaned it as the port for the pcv valve was plugged solid with carbon. I have not replaced the cap and rotor as they seemed to look fine. I have not checked the fuel pressure because it will break the tires loose upon take off and I don't think that would be possible if the pressure was low, would it?

I am doing a side job and this thing has a rough idle. I put the scanner on it and pulled code 43 ESC and a ritch and lean code from the O2 sensors. I know the O2 codes are probably from running rough. It has been a while but could the knock sen be the problem or the ESC itself? I looked for the ESC by the throttle body but didn't see it. I remember what they look like but this is a late model 94 are they some where else?

Like the title says, 89 Chevy G20 V8 5.7l. When coming to a stop or in idle while in drive the van will shut off. Here are the symptoms.1. When driving below 10MPH the oil pressure gauge will drop to 0 and then the van shuts off.2. When starting the van a nice white plume of smoke comes out of the exhaust.3. Van had been chugging a bit when stopped and the AC was on. I replaced the fuel pressure regulator today thinking that possibly the engine was getting flooded when slowing down, but that did not fix the problem.

97 chevy k1500 with 305, engine rebuilt by shop 60k ago, last few months only drove truck 4-5 times, last time driving gave p0306, new plugs, wires, cap, rotor, cleared code, now gives p0300, took intake apart removed spider, sprayed/scrubbed each injector and poppet with cleaner, but no way of cleaning the line between the injector and poppets. No change after cleaning. Also ran injector cleaner through tank. All vacuum hoses look in good order, sprayed carb cleaner around intake to check for leaks at intake/throttle body, no leaks.
Checked TPS, IAC, MAF, Coil and fuel pressure, all good except fuel pressure was 52-54 while idle, replaced fuel pump, screen filter and main filter, cleared code, rough start and rough idle still gives p0300. Checked coil with ohmmeter, between posts A & C, Chilton says 0.1 ohms, i got 0.5 ohms, went to autozone and had them check a new coil, it have 0.5 ohms......? Can drive at higher speeds and runs smooth, but idle is poor almost dies.Checked fuel pressure after pump replacement, still ~54 psi. Stumped and don't want to throw more parts at it without a proper diagnosis. Have a OBDII pocket scan tool, but can't find manual, will try to find manual and see if I can pinpoint the misfiring cylinders.
