I purchased the vapor canister vent valve and purge valve as the service engine light has been on and this are the contributors. I want to know the location of these and how to access. It appears that they may be by the fuel tank and I don't know if I need to lift the box or something to access them. It is the 5.3L V8.
View 5 RepliesI have a 2001 1500 with the 5.3V8 motor (ext. cab sb 4x4 LT). I was my dads and had the service engine light on for a long time for the P0446 code. I replaced the vent valve and the purge valve and light keeps coming back on. Usually can go for a day or so and then it comes back on and I get the same P0446 code.
View 3 RepliesDriving while in 4x4 HI up a hill the truck started to slip. I stopped, shifted to neutral, and engaged 4x4 Low. I shifted back to drive and started moving up the hill. The engine started to lose power and the "Service Engine Soon" light began to blink. I put the truck in park. As I let it run a little bit, the engine started to shake as if something was very imbalanced. I went to check under the hood, and confirmed that it was shaking quite noticeably. There was no grinding or clattering of any kind though.
I turned the truck off for a bit, and then restarted. There was no light or shaking upon starting up; but as soon as I put it in gear and started driving I could tell it was losing power, the light came back on, and the shaking ensued. This occurred in 2wd, and both 4wd lo and hi. I parked it at a neighbors place and there it sits for now.
I plan to try and get the codes read. My other vehicles can't make it through the snow we have right now, but it is suppose to get warm later today and might melt enough for me to get one out. I also live out in the country, so the nearest auto parts place is about 20 miles. Same with a dealership service shop. I'm hoping I can buy and return a code reader from an auto parts store to assess if this is something I can diagnose myself or not.
It is the 6.0l gas engine with the 4sp automatic transmission. The truck also has about 107,000 miles.
I just purchased my first foreign car ever. it is a 2002 Elantra it idles very rough changed plugs using NGK and wires new fuel filter and ran 2 full tanks of high grade fuel with STP fuel injector cleaner. but had no effect on idle also have no check or service engine light. What to check next?
View 3 RepliesTwice now (and maybe a third time once I start my van again) we've had problems with the van chugging and then the service engine light blinking. Both times it happened in the past, we took it to a mechanic who said it needed a tune-up - new spark plugs, wires, etc. I'm curious as to why this keeps happening. Mileage is around 105K. It first happened last summer, second time was in December. Now it's March. What could cause this problem to repeat?
View 2 RepliesI have a 2001 F350 and my service engine soon light came on. For a while it went on and off and every time it came on the engine ran rough and I lost some power. I pulled the valve covers and checked the UCVH and everything was fine that I can tell I even made the shims out of quarters and put them in. After putting it all back together its still doing the same thing.

I checked the gauge and it is running at 14 consistently. But the service engine soon light keeps coming on...I clear them and they come right back... Alternator is only 2 years old and not a rmf..
View 1 RepliesTruck started losing power then service engine light came on, drove about another mile then it just stalled ( almost home lees than a 1/4 mile). Got out open hood oil everywhere on top of motor. Looked under truck and oil all over the road. Looked back where I was driving a line of oil as far an I could see. Checked oil barely any on stick. Where should I start hpop or plug?
View 7 Replies2001 01 1.8t... Hoping this isn't a bad ABS module. When I bought the car, I was told it was a bad wheel sensor in the drivers side. But, the funny part about this is its not on all the time, sometimes it doesn't even come on and the dash is normal.

View 4 Replies2000 Ford ZX2 2.0 ....I've got approx. 79,350 miles on this car. I'm the original owner. The "Service Engine Soon" light came on. I took the the car to an Advanced Auto Parts store, they hooked up their handheld computer to the car and told me "it might be an oxygen sensor or poor fuel octane", he suggested adding an octane booster and see if the light stays off. I did that,but two days later it came back on, the idle seems a little ruff when stopped at a light.
View 5 RepliesI have a 1999 F-150 w/ 4.2 V6. and auto trans, truck has 219,000 miles on chassis but only 25,000 on engine and 10,000 on trans. I've been getting obd codes p0705 and p0715. I replaced the position sensor on outside of trans. but I continue to get the codes off and on again. I noticed that the O/D "OFF" light on the shift selector blinks simultaneously when the "service engine soon" light comes on. I've noticed that there is no low gear unless I have it in D from a dead stop, and not even when downshifting manually.
View 1 RepliesMy crew cab 2001 has 75K miles and is well maintained and garaged. Every once in a while the engine will just quit while driving just as if the key was turned to neutral all dash indicators light up but just quits running. Turn the key to start and hear the engine cranking but won't start. Sometime in park it just cranks however I noticed that when I move the shift lever into neutral and depress the brake it will crank and start sometimes.
I don't believe it's a fuel problem. Could it be a loose wire in the column?
Ignition coil replaced twice in 3 weeks, engine still cuts out randomly and "service engine soon" light flashes on.
View 3 RepliesI have a 2001 2500HD P/U with the 8.1L V8. I have owned the truck for ~5yrs and used it with everything towing. For about the last three years, I have noticed that when the truck is in gear (Either Rev. or Drive) the engine idle almost acts like it is missing. It doesn't do this at higher RPM's (say over 1K) while driving.
Last spring I did a tune up (Plugs and wires) and a few of the plugs had quite a bit of build up so I figured that was what was causing the issue. For about 1wk after the tune up it seemed to clear things up (at least I didn't notice it), but then resurfaced.
My question is: should the "Coil" parts that feed each spark plug need replacing, or could they cause this symptom? The ignition system on this truck is a bit different that what I am used to seeing, so I am not sure where I should start looking for the problem.
Also, there are no error codes being thrown.
Any way to reset this so it goes out?
View 1 Replies1996 Silverado 350 engine. When I turn ignition key on, all system check lights come on as they should except "check engine soon". If I connect code reader the light comes on and will come on the next time ignition is turned on but only one time. The second time you try it, it does not. What would cause this?
View 3 RepliesMy service engine light comes on after my camero has been running for a little while some times it takes about 1o minutes before it comes on it runs like there's no problems with it. I know there's a way to check it with a paper clip but I forgot what spots to put it in to get the codes. Its a 1989 camero r/s 305 tpi
View 1 RepliesI just bought a 1994 s-10. I found out it needed the head gasket replaced, so I had that done. I picked it up last night, and found that when I'm going at speeds over 55 mph, the service engine soon light comes on. When I let off the gas and slow down, the light goes off. The engine sounds fine, and the service engine light has never been on before in the month that I've had the truck. The oil and coolant levels are good. There is no hesitation when going at higher speeds. The only problem is that the light comes on.
