Kia - Sportage :: 2002 4WD Won't Work In Warm Weather / Misfire Like Electrical
I have a 2002 Kia Sportage 4WD. It runs great from fall thru winter and spring. But when summer comes and the ambient temp gets into the 80's it will run good for @ 5 to 10 miles then crap out. Sometimes it seems like it's starving for fuel but others its more of a misfire like electrical. I've replaced the fuel pressure regulator, the intake air temp sensor and even the catalytic converter. Spring is coming soon and I really like this car.

Ok after finding out I had a bad battery @ Toyota shop they also say the scan is reading an exhaust leak ( I could hear that one ) they also say there is a misfire on cold starts should I worry and what could it be or is it a misread from the other two ?
View 4 RepliesPrius (2001-03) :: 2002 Check Engine Light Codes For EVAP System And Misfire
My check engine light came on the other day, with no symptoms or problems. Today I stopped at the Auto Parts store and had the codes read. They were P0440, P0441, P0446, and P0301. They are for the EVAP system and misfire.
I had read here that one of the codes could be for the gas cap so I tightened it and then, also as read on here, disconnected the negative 12 V battery cable to perhaps clear the check engine light. I was curious.
When I started the car again, I now have not only the check engine light, but the red triangle exclamation point. How would you proceed? The 12 volt battery is around 5 years old. The entire exhaust system was replaced last year.(not O2 sensors though)
The hybrid battery was replaced at 70,000 miles and I now have 110,000 miles on it. I really wonder why disconnecting the battery and reconnecting it caused more error lights to appear? Also, the Auto parts guy said his code reader was fine for my car but I seem to remember here that there may be a special Prius one.
Prius (2001-03) :: 2002 - Won't Start - Chip In The Key?
I was at Walmart today and FINALLY remembered to get a couple keys made for my 02 prius. I have been taking somewhat of a gamble considering I only got 1 key when I bought it.
I tried the keys in the trunk. Cha Ching! Unlocked and locked the doors. Cha Ching! Put the key in the ignition and turned it. Cha Ching! Went to start the car and Nothing!!
I could turn the car into accessory and into the run position, but it would not put the car in ready mode. At first, I thought my battery died. I took a deep breath and put the "Toyota" key in and she started right up...
Prius (2001-03) :: 2002 - Engine Won't Start?
I own a used 2002 Prius and have only been driving it for about two months. In the last week it has given me some trouble on start up. I turn the key, but the engine will not start. Unlike some of the other comments I've seen here, I'm not getting any warning messages when my car won't start. I turn the key and the dash lights either come on half lit or not at all, the computer screen doesn't light at all when this happens. If I hold the key in the start position for a few (up to twenty seconds) it will eventually turn over and start, but that seems to be draining the big battery and doesn't seem like the best way to start the car. This happens about 2 out of every three times I go to start the car and it doesn't seem to matter how long I've had it parked - could be an hour or overnight. Conversely, it could be sitting for a day and a half and start without issue. All in all, there seems to be no obvious condition that would cause this, and I was curious to know what I should troubleshoot and in what order. As with many people these days, money is scarce and I don't have the money or time to keep it in the shop for a week for diagnostics, especially when it might be something I can easily fix on my own.

I pulled the traction battery...remanned it with great success computer very happy with results... drove it for a week. Took it to Walmart to have oil changed... Got in car , started fine...new oil made motor even smoother....then in 200 yards at traffic light , motor died with unusual sound... pulled over and restarted...but would die. Lights all over dash on.
made it back to oil bay...engine would not restart.
pushed inside and would start and then die... then was rattling when dying
checked aux battery with testers , both indicated dead cell 10.25 volts
tried to substitute a new battery via heavy jumpers... got it to start then die..,..then no try at all
I have read forums ,,,that indicate after 3 tries on a dead aux battery , computer will immobilize it
Have tried replacing with a new lawn tractor battery .but seems the car is immobized . Read codes with Mini VCI, and was able to clear all codes but the immobilizer code.
Prius (2001-03) :: 2002 - Code P3006 And Won't Start?
I just purchased a 2002 Prius from a government auction. The car had to be jump started at the auction yard. It ran for awhile and then died before I could put it on the dolly. I jumped it again, load it and towed it home. When I got home I jumped it and drove it off. I tried to charge the 12V battery on a 2 amp current, but it wouldn't charge so I replaced it with a new battery. Now the car won't start at all. Don't worry, I did not reverse polarity at anytime. Here's what is happening now....

Pulling into parking lot and the triangle and exclamation light appear on dash. Drive about an additional hundred feet with what felt like lower power and no noises.
- Check 12V after about an hour and it reads 12.4 volts.
- Read codes and get P3125 sub code 325.
- Temperatures and HV battery numbers all looked good.
- Clear codes and immediately code comes back with no start, nothing. Did this many times.
This code and sub code lead to the inverter failing. Being that there was no noise as a MG2 stator failure this also leads to an inverter failure right as the MG1 motor starts the engine? Inverter pump still running good as it was recently replaced along with ATX fluid. Within the last two weeks two HV modules have been replaced.
Ford F-150 - 1997-2003 :: 2002 - Hard To Start When Warm
I have a 2002 F-150 4.2L that is hard to start when warm. Cold starts are no problem, except in the below 0 F stretch last winter. Also when it is a hot start it is not an issue. Only when it has sat for a few hours does it have an issue. The following is the list of things that have been done.
- New Plugs,
- New Plug Wires,
- New Coil Pack,
- New Fuel Filter,
- Clean Throttle Body,
- Clean Mass Air Sensor,
- Clean Idle Bypass,
- Replace EGR Vacuum Control Switch,
- Manifold Leak Repair (Ford Dealer),
- Throttle Body Stop Adjusted for more idle speed,
- Check fuel pressure (40 psi key on, drops to 35 psi static).
Elantra XD (2001-06) :: 2002 - CEL Flashing On And Off / Cylinder 3 Misfire
I have a 2002 Elantra with 123k on it. It has been having issues with poor acceleration, rough idle, surging, and the car just overall shakes sometimes when driving. The check engine light started flashing on and off periodically today, so I coded and it and it gave me P0303, which is a cylinder 3 misfire. I checked the spark plugs, and the cylinder 3 spark plug was pretty bad, so I went ahead and replaced all 4. The wires were in mint condition, so no issues there. I also put fuel injector cleaner in just for good measure. When I went to test the car, startup and acceleration/reverse were better, but the other symptoms still persist. What I should check next???

My Santa Fe driving me crazy. Have a 2002 Santa Fe 4 cyl with a problem. It will start when cold and run normal about 2 minutes. Then it starts running erratically like a misfire. If you let it idle this way it will stall quickly and not restart until totally cold again the next day. If you catch it quick enough and continually pump the throttle it continues to run rough until it starts to warm up. As it warms up the engine slowly improves until it reaches operating temp. At this point the misfire is much less but still there. If you shut it off for more than 10 minutes it will not start until the next day. There are no codes at this time. I have changed the coolant temp. sensor, the cam position sensor, fuel pump and screen, spark plugs and wires. I have also verified all timing marks on the crank, cams, etc. The crank sensor was replaced about 40k ago when the timing belt was replaced. What can I look for now???

I have a 2002 Santa Fe 4 cyl that is giving me a problem that I could use some advice on tracking down & fixing . First & most important is a code P0302 # 2 Cyl misfire. How to check the ignition coil pack , injector ,& wire for this cylinder in home garage with normal tools & meter . Is there a you tube displaying how to do this step by step ?
The other problem which I don't have the code for at this time is that some part of the exhaust is not getting warm enough & this also put's the check engine light on . Will get back on this one when I solve the main problem Misfire.
Santa FE SM (2001-06) :: Overheating / AC Blow Warm And Hard Start
I have a 2004 Santa Fe and have recently noticed the following problem. When it is hot outside (95 degrees) and car has been idling for a while, suddenly the A/C will start blowing warm air and the temperature gauge will start creeping up above normal. It hasn't fully overheated as when this occurs, I shut off the A/C or start moving and it returns to normal temperature. The A/C will then work properly again. Also, when this happens, if I turn the car off and then try to start it again a few minutes later, it is very hard to start but eventually starts. It can easily be reproduced, but I want to try to understand possible cause before taking it to a dealer. I was thinking maybe fan going bad, or fan switch.
View 4 RepliesSanta FE SM (2001-06) :: Misfire Codes On Start Then Runs Fine
Often, when starting it will run rough and throw different misfire codes. Most of the time it smooths out in short order (a minute or less). When it doesn't smooth out quickly, it smooths out when I clear the code. Also, rarely it will start very hard. I have to wimd out the starter pretty good to get it to start. All that I have done is cleaned the MAF sensor.
View 3 RepliesPrius (2001-03) :: Engine Off After Warm Up And Wandering At Interstate Speeds
Wondering if this is just my car or something that's common with the Gen 1? After my car gets warmed up, just over 150F, the first stop or coast the engine will shut off. But unless I stop again and wait the 5 seconds or so for the engine to stop, I can't get it to shut off again down a hill or coasting. I need to stop, let it shut off, then after that all is good. Lift foot, engine off. Drives me nuts when I have a long hill and it doesn't shut off! (I'm using a scan guage II to watch the rpm and water temp)
Also a question on the steering, we took a 550 mile trip this past weekend, all interstate. Although it was a little windy, the car takes constant steering input to keep it in the center of the lane. It did get old after that many miles! Common problem? I read a little on the Gen2 having problems like that but the solution was dealer adjustments. The previous owner did have a new rack put in in 2008.
Prius (Gen 3) Fuel :: 2013 - Does The Car Always Warm Up After Each Start Up?
Well I bought my Prius 2013 II about a month ago so I have been learning alot about the car as I go and reading how to effectively get the best mileage from the car. I have only filled it up once so far but one thing I am trying to figure out is the mileage at start up. I have read that you get the worst mileage when you first start up the car after a nice period of no driver which I understand. They say 5-10 minutes of driving and it should be fine.
But my thing is it seems like every time I start my car up it goes through the whole slow mpg start up. Is that normal? Let me give you a example. I had to drive from work to a movie theater which was about 9 miles and I averaged around 68 mpg. Yes right when I started my car after a 8 hour shift the bars on dashboard next to the MPG were going up and down and would stay around 25-30 mpg for the first few minutes but would eventually go back to 99.9 when i was coasting.
Well anyways I drive to the movie theater just to get out and get a gift card for fathers day. So I am only gone for maybe 3 minutes. I get back into my car and start it up and my fuel consumption plummets to 20-30 mpg for a few minutes before it goes back into warm up mode. I was told your car should only do that your initial warm up after it hasnt been started but it seems like when I do many errands and I have to turn my car off for whatever reason. My gas plummets until I get the ball rolling again. IS this normal?
Prius (Gen 3) :: Can't Lock The Door When Start Up To Warm It?
how can I unsure someone won't drive off with car when I start up to warm it? I mean I can't lock the door with it running. Not going to install a remote start (if that's even work) Wish it would not drive when put into gear to ward off thief, without key fob. Is there a solution? 2015 regular Prius.

2001 V6 Passat with 125k miles throwing a P0430 code.
Having trouble on cold starts, takes about 10 minutes to finally get it to turn over. When it does the idle is extremely rough. For the first 1/4 mile the car bucks, stutters, and misfires. After that it runs fine and starts fine when already warm. I am noticing slightly decreased gas mileage but nothing major.
Valve cover gaskets were replaced 2 months ago, but were leaking oil for at least a year before I could afford to have them replaced. I am still noticing some oil leakage, however not as much as before. I have had both O2 sensors replaced twice in the past 5 years. Timing belt was replaced at 98k. What might be causing the starting issues?
Prius (2010-12) Fuel :: Car Takes Too Long To Warm Up From Cold Start
It seems like it takes an awfully long time for the good mileage to get going from a cold start - even when it's warm outside. The last 5 miles of my commute are great, but the first 10 miles not so much. How much effect does ambient air temperature have on this process.
