Just started this. The car starts normal and runs great until it gets to temp or about 20 miles, then it begins bogging down. Has no power under load,(going up hill or giving extra gas), will load up then backfire, slowly losing power and speed, then cannot get gas to it at all, eventually shutting down. After sitting for a few hours will do the same thing again.
View 1 RepliesMy 2000 VR6 Jetta has an annoying problem of hard starting in warm weather. Last summer through fall when the weather was warmer, it would often crank but not catch. All winter it is fine. A jump will usually gets it after a while. Replaced the battery with limited success. I park in the shade whenever possible. It has the manf. alarm system, and, also, but not always, it is accompanied by key not turning off the alarm. Do not have remote. Replaced the Fuel Pump Relay. No success. Cannot predict, so I don't want to have it sitting at the dealer for days on end.
View 2 RepliesCar & History:- 99 Jetta, 2.0 AEG engine, manual. 86,000 miles. Bought at 70,000 miles 3 years ago.- low oil warning once in 2013 maybe. since been using 5w-40 synthetic and used Ceratec additive once. Been doing regular oil changes.- replaced original fuel filter at 80,000 mi- gaskets have been going. Replaced thermostat and gasket. Replaced leaking oil cooler gasket. Valve cover gasket has been leaking for at least 1 year. Will replace.- Replaced timing belt, tensioner, water pump, and serpentine belt at 84,000 miles.- Flushed radiator at 84,000 miles.- All break rotors and pads at 80,000 miles- Replaced battery at 75,000 miles- Gas mileage: 26mpg
Problem:- the sound is similar to a tapping. This has been going on for a year or more.- very noticeable and loudest when cold- worse in the lower gears- diminishes once warmed up (5 minutes)- happens only under load - so 5th gear and letting off the gas pedal (coasting) it's not noticeable.- JUST TODAY: 20 degrees F, and wouldn't start on first try. Cranked for 6 seconds probably. Second time I turned the key, it started no problem.
Things of note:- By peaking behind the engine, it looks as though the oxygen sensor wire covering (pre cat) is getting a little frayed at one spot.- When I bought it I noticed new spark plug wires.
My thoughts:- Exhaust manifold gasket (to the head) is bad. So when it gets warm the bad gasket expands and stops the noise.- It's not the valve lifters because the noise goes away when warm and not really heard when gas pedal isn't engaged.- Replace the O2 sensor?
Attachments:- 3 audio files. I put my car under my hood and went for a drive. You can hear when I engage the clutch, the ticking sort of goes away. - Pictures of the frayed O2 sensor wire ...
I have a 1996 VW Jetta GL 4 cyl. 2.0L. When the temp. start to warm up the car won't start. I don't know if its the temp. outside, or in the cabin of the car. all the dash lights turn on, and accessories turn on. sometimes I hear a clicking noise, which I think is the sound of electricity going to the starter. I have replaced the starter, alternator, & battery. I had a family friend mechanic look at it for about 3 hrs. and he couldn't figure it out. I have a suspicion that it might be the ignition switch faulting out, but how would I know for sure with out taring apart the steering column?
View 6 RepliesWhen I fill my 2002 VW cabrio, the fuel nozzle keeps clicking off. I took it to the service department at the dealership and the service manager told me that there is no vent tube to clean out, no carbon filter and the sensor for the ORVR is at the inside bottom of the tank and the only POSSIBLE solution would be to replace the gas tank. This doesn't feel right given the other discussions on this board. Could the dealership be misleading me?
View 10 RepliesI have noticed that due to warmer weather and more Prius C owners that the MPG's are going up. No many in the 40's mpg anymore. I enjoy people posting and obtaining over the EPA of 50 mpg, the 60 mpg figure appears to be fairly easy
to obtain with the Prius C.
On our Prius the last mpg was 52.3 calculated this is real world driving with my wife driving 75% of the time and she does not drive strictly for MPG's.
I believe we should all take a minute and pat ourselves on the back as all the countless gallons of gas we our saving and will be saving for our friends and neighbors who have no choice but perhaps to drive large cars and pickup trucks...
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?
Here in the northwest the weather has been dry and temps in the 40's to over 60 degrees. The mpg's have increased about 5-7 mpg over just a month ago.
View 5 RepliesI can't believe what I'm saying as I always say to start driving (slowly) to warm up the engine. Besides, who has the time?
But, this AM, I was stopped as soon as I exited my driveway as big garbage trucks blocked my cul-de-sac street. The engine went through the warm up cycle as I waited stopped and later, I went through my usual commute.
The thing is the commute ended at 67 MPG (indicated). I usually get "only" 60 MPG on the very same route, unless the engine is prewarmed before driving and I get exactly 67 MPG. I always clear MPG trip counter before driving on a daily bases.
how much fuel is consumed during a typical warm-up period for the Gen III? I realize there are variables related to ambient temperature etc..
my interest is to get a baseline consumption figure to compare warm-up saving devices/techniques against.
I have a recently rebuilt 400 with a mild cam and Tmeyers flat top pistons. The carb is a 600cfm edlebrock that was bought new and installed a few months ago.
The issue I'm having is if I'm driving around and shut it off to run in the store its hard to start when I come back. I end up having to floor the gas to get it to start. When it's cold I tap the gas and turn the key and she lights right off. Could this be an issue with vapor lock? Why does it go away if I floor the gas?
Only other thing going on is when accelerating the engine runs noticeably smoother above 2700rpm. It's a little boggy below that. Probably two different problems but I figured I would throw it out there.
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.
View 15 RepliesI just purchased a 1989 F250 with a 5.8 motor. Great truck for its age. Ive owned other Ford trucks in the past and my Dad had them as a kid. Love them.
When I bought the truck from the 2nd owner it had a problem so I bought this truck with the problem figuring with my past knowledge I could fix it. Not the case. When I got the truck it would start fine and run really great but when it got warm it seems it would die and I would have to wait till it was cooled down to start back up and again it would run fine. Well the problem got worse and worse and now it wont run at all.
It will run on starter fluid so that leads me immediately to the fuel pumps. I say that plural because none of them will run it seems. I did a fuel pressure test at the shrader valve at the top of the motor on the fuel rail and I get no pressure at all when I turn the key. The relay in the engine compartment seems to be working to as I can hear it. I put a new on of those on to to be sure. Leads me back to the pumps again. I replaced the external pump on the fuel rail and I know thats working. I replaced the fuel filter to while I was there.
Is it possible to have BOTH fuel pumps in the front and rear tanks go at once? Seems unusual. My other F150 with dual tanks worked great and when the back tank pump went I could just switch it over to the front tank.
I have a may 2003 6.0l f350 4x4 ,autoenginuity scanner, recently bought the truck starts fine and idles well then when engine get warm it starts to smoke unburnt fuel (white) volume of fuel desired on scanner goes from about 14 mm~3 to 27mm~3 and starts to run rough if you depress the acellerator the motor smooths out and the fuel desired goes down. No coolant smell. egr cooler removed ,oil cooler replaced, exhaust back pressure sensor and tube cleaned .ebp sensor koeo 14.2, eo 17 but jumped to 54.0 when map was at 17, bp 31.20 .... The AE is new to me Also found a superchip tuner under the back seat ...
View 14 RepliesI have a 1989 GMC suburban V8 350 5.7l that will not start. I have replace the following fuel pump and sending unit, fuel pump relay, ECM computer brand new, new fuel filter. When I go to start it the fuel injectors dont spray fuel into the combustion chambers verified fuel injectors still work by bypassing them and they spray fuel. Fuse's are not blown. I have been told the oil pressure switch might be bad but I'm at my end of sanity on this.
Additional Details : Tried spraying fuel into the throttle body and still no fire, ignition module and ignition coil where replaced 15,000miles ago.
Today, my 1995 E150 suddenly started acting like it was running out of fuel Lucky for me, this happened close to both a parts store and my usual mechanic's shop. Unluckily for me, it happened on Saturday, and my shop can't get to it until Thursday. So here I am, hoping to do a fix in the meantime.
At first, it seemed that it must have been the fuel pump, because I couldn't hear it come on when I turned on the ignition. Then, a guy who said he was a mechanic told me he could hear the pump cycling, and that my problem was the fuel pressure regulator. So he managed to start the vehicle after a few tries, then it crapped out again. He did this twice. Then he went away.
I called every parts store in town, and none of them had a fuel pressure regulator for my vehicle, and the earliest any of them could get one was Monday. But I knew I was due for a fuel filter, and I'd changed filters on this vehicle before, so I got one of those and put it in. To my delight, the van started right up and idled beautifully. In fact, it ran beautifully for about 15 minutes, until I came to a slight rise, then it crapped out again. It still started up and idled smoothly, and even revved up smoothly, until it reached a high idle speed, at which point it crapped out. I did manage to limp into the parking lot of my shop - which, again, can't get to it until Thursday.
So my question is: does this sound like a fuel pressure regulator to you? If so, is that a job which somebody with a reasonable mechanical aptitude (i.e., at least good enough to change the fuel filter) should be able to feel safe doing? If the answer to those two is "yes" (or even if it's "no")....
So my 7.3 started sputtering and lost power, died on the side of the road. I wasn't far from home put about 8 gallon of diesel in the tank with a couple of fuel jugs and it fired right up.
Gauge was reading 1/8 of a tank and low fuel light did not come on. (low fuel light comes on when you start) Gauge came up to about 1/2 after putting fuel in.
What happened? Gauge was always reliable and low fuel light always did work. Only work done to fuel system was had new tank straps put on a couple of months ago.
I have my aux fuel tank pump hooked to upfitter 3. It has worked perfectly until this week. I started to transfer fuel and the aux fuel gauge and fuel pump both quit. The led on upfitter switch 3 still illuminates, but no fuel pump. I found fuse 9 on passengers kick panel is for upfitter 3. The fuse was good. Is there another fuse somewhere for the circuit I've missed? I can trouble shoot the wiring if necessary, but it's tough to do all behind the left side underbed box and not easy to get to. I've missed something simple before I go further????
View 14 RepliesI have a 2006 F250 c/c LB and I am curious, how much fuel is left in the tank when the low fuel light comes on?
View 8 RepliesThis van has had a couple of fuel pumps, no surprise there, and i need to look through my paperwork and find out how many miles the current one has on it, but it has the STRANGEST habit I've ever had on any vehicle. Starts fine, runs fine, no fuel pump noise when van is running, and when you turn it off, the fuel pump creeks on and off for several minutes.
I mean a strange creaking noise almost like a shorted electrical device or a vehicle's brakes when you park it on a hill and the breaks creak as it settles into place. I'm probably doing a lousy job of describing this but i don't know how else to describe it!
ALSO, if you lay under the van and wait til it stops creaking, you can tap the bottom of the tank and it will creak for a few more seconds. You can tap repeatedly and make it creak more. Is it about to explode? Can i trust it on a road trip?
I have a F-250 4WD with 7.5L which has a MC/Holley 4180c sitting on top. It was getting very poor mpg (like 5-6 miles/gal) and then was getting harder and harder to start. This progressed rather quickly to not starting with fuel coming out of the primary vent tube. I suspect it has to do with the primary float stuck open. I was considering rebuilding the carburetor. Is this over reaction prematurely or is there something like float adjustment that may rectify all of the symptoms described. If a rebuild is in order what is the information I would need to ensure getting the correct rebuild kit. Info that I have so far from research is it is Motorcraft ID #E5HE-9510-MC.
