Chevrolet :: 1987 - Check Engine Light On But Only When Driving Uphill?
Feb 19, 2013
I'm driving my mom's 1987 Chevy Spectrum, which has about 190,000 miles on it. The Check Engine light comes on daily, but only when I'm driving uphill. The Chevy dealer says because the car is so old, it will take several hundred MORE bucks to find out what the codes mean. Doesn't seem to matter how full the gas tank is, or how steep the hill is. Other than this light, she just keeps going and going. Do I need to track down the cause? Might there be other symptoms that would diagnose it that I'm unaware of?

My 2003 Chevy Imapala went over some large water puddles and shortly after a check engine light came out. My local auto store did a check and stated there is a possible problem with a senor. If the senor got wet, could it even give the computer a good reading? Would it probably give a totally different reading once it dries?

2006 F150 Triton 5.4 Motor... It's been over a months journey with fixing this truck....
How it started: had an oil change, a while back, on long drive after, check engine light started flashing as I accelerated up hill so I pulled over and in a while it was ok, but couldn't get on the gas too much, or it would cause that flashy light thing.
So fast forward to now, after driving it with an intermittent miss for a while, was driving it to work and the miss became a shudder, and she stopped going over 30-40, and runs extremely rough.
Steady but loud idle.
Replaced all plugs with motocraft plugs and new coils all around. No change.
Finally hooked it up to a computer and got random misfires, now it's saying
P0174 bank 2 too lean,
But it's bank ONE that's the only side misfiring.
Here are the freeze frame details:
Frame 1 Mod $00
MIL Status Off
Troub Code P0174
Abslt TPS 24.3%
Eng speed 1665
Baro PRS 71 kpa
Calc Load 100%
[Code].....

my 2002 chevy impala has had the check engine light on for a while now i took it to a shop and he said my engine was bad. I asked for the codes he got he said he just told me my engine was bad why do I need codes. I talked to another mechanic this week and he said he'd look at it, that it might not be that because I should of got a print out for what I paid for. SO I got a oil change today and when i left I saw in the comments that they put class 2 oil pan leak and a class 2 transmission leak. Could that be why my check engine light is on? How bad is a class 2 transmission leak?

Had the check engine light come on, and when I checked on the code it gave a 4th cylinder misfire. Autozone instructed me to simply replace my spark plug with a new oem plug.
I replaced the spark plug as instructed. After about an hour of driving, the check engine light goes off and I think, great! Problem solved. However, another hour of driving and the check engine light is back on again, without going away.
I headed back to autozone to get a readout, just to find that it's the same code. So I put another spark plug in. Same result - check engine light goes off after an hour, only to come back on again permanently after another hour.
Now, normally I would think, this must be the spark plug line that needs replacement,however I am sure there must be some clue in the fact that the check engine light turned off for an hour.
By the way, not sure if relevant, but I also found a lot of build up around the spark plug before I initially changed it.In fact, there was so much that I had to scrape around the plug with an awl, and blow out the crud with a compressor,just to get my socket into place without there being crud in the way.
Any clue what that check engine off/on clue might be?

If I hit a bump too hard the Check Engine light comes on because the gas cap pops out. Dealer told me this is a common problem with many of the Chevy models earlier than 2007. GM doesn't have a solution, either.
Since none of these cars have a locking mechanism I decided to get a locking cap at NAPA because the locking mechanism would hold the cap in place. Nope! The locking cap is even worse.

After filling the gas tank yesterday, as I was on my way to work, the check engine light came on. For the last couple of days the temperatures outside have reached 118 degrees. I have checked the oil and coolant and have resealed the gas cap as well, yet the light still remains. The research I have done leads me to believe the problem may be the catalytic converter, but I'm wondering if there is any further troubleshooting I can do without heading to a mechanic.

My check engine light keeps coming on. I've had a couple of mechanics look at this and they say the code indicates the transmission is going out. the transmissions does not slip or have any signs of going out.

Went in due to the check engine light coming on and found out I had a oil leak in both oil cooler lines they wanted to charge me 350 per line and 200 for labor which brings the total to 900. Are they over charging me if not is there a cheaper fix for them? 2007 impala 3900 v6....

My 2003 MC SS has been acting up, the check engine light starts flashing at me and the car starts shaking when I turn the AC/Heat on. I know nothing about cars and before I take this to a mechanic, what might be the issue, I do not want to go somewhere and get totally ripped off.

I just bought this used truck, 2005 Chevrolet Silverado 1500 extended cab. I noticed some shaking while in idle when I got it back home. The check engine light came on a day or two later, and I recently had a diagnostic test ran on it at the local AutoZone. It came up that I had a P0135 o2 sensor (bank 1 sensor 1) malfunction and a P0101 Mass Air Flow Sensor signal performance issue. The check engine light comes and goes. I stopped by Walmart for about 10 or 15 minutes and when I got back into the truck, the issues reoccurred. For about a minute, the check engine light actually started blinking! And then went away and started running normal again. Its upper confusing. I bought some MAF cleaner to use on it tomorrow and figured that wouldn't definitely clear up my issues, but I'm still wondering if the MAF sensor is enough to warrant the CEL to blink like that?!

This has happened five times within the past couple of months. I have a 2004 Chevy Malibu Maxx LT. In all cases, I was accelerating while going uphill. I am in Chicago so by uphill, think expressway ramp. The Charging System Light and warning bell come on for about a second and then shuts off. When I get home, I check the battery. In all cases, it is fully charged. The battery is six months old. What could be causing this?

My Check engine Light comes on with a P0410 Code. It used to come on every 6 months and I would get it cleared. Now it is coming on about every month. I can't find much about it. Is this something I should get fixed right away. where is it located?

I have a 1998 chevy 3500 2wd pickup with a 454 engine. The check engine light is on. I have had the codes read and they were for a MAF and MAP sensors. I have replaced both. The check engine light is still on saying that I have a bad MAF sensor. I replaced it again. The check engine light still is on. What else should I look at to fix this problem??

I have a 2004 Chev Avalanche. Several times recently my check engine light comes on, the truck dings 3 times at me and a dash script tells me to tighten my fuel cap. I do and the light goes out within a few hours or the next day. I have changed fuel caps twice. This week the light came on, has not gone off and at least 3 time it has told me to tighten the fuel cap which I have done.

When I tried to turn left yesterday, my car suddenly stopped with both the "check engine" light and "battery" light on, but the heat, headlights and radio were working just fine. I turned off the engine, and waiting a few minutes, ad then restarted the car, and everything is fine. I do not drive the car today. My question: is this a problem with the battery or the electric line? When the "battery" light is on, can i conclude it's a problem limited to the electric line only rather than a fuel line. My car is Chevy Malibu, 1999, with 90,000 mileages on it.

So I recently bought a Chevy Impala with about 150,000 miles on it. The check engine light is on and sometimes it will tell me my coolant levels are low. I filled it up with coolant and the message still comes on sometimes. Also, when I'm driving, I can feel my rpms go way up when I press the gas, but they car won't accelerate for shit. Sometimes the check engine light will blink, which I've heard is for safety, and my car will barely accelerate at all. I can drive it around town easily the way it is now, but I don't want to risk ruining it. On top of that, my radio and lights will cut in and out sometimes and get better the more gas I give it.

My 2008 Malibu service manual states that the check engine light should briefly come on when I start my engine. When the engine is cold this does not happen. Also, it happens infrequently when the engine is warm. My Chevrolet dealer says this is normal as the light checks out when tested. Chevrolet has not given me a difinitive answer on this. My concern is that if this is a problem it may surface at another time when the light should go on and cause damage if not attended to. If the manual says the check engine light should go on when the engine is started and it doesn't, doesn't this mean something is wrong?

I have an 07 Impala. Just recently, the engine light came on. I contacted OnStar who did a vehicle diagnostic and told me the problem was the emission control and further told me I should tighten my gas cap which might take care of the problem. It didn't. How important is it to take care of this?
