After driving a while, shut down the engine, return to start a half-hour later, no response when key turned. Wait a while, everything's fine. We've chased all the under hood wiring connectors, all are clean and tight. Replaced the ignition switch. Have not yet been able to get it to fail when it's in the mechanic's shop. Problem worse in warmer weather, but it has misbehaved in mid-December, too.
View 1 Repliesmy 2007 3.2 s80, 75 K miles, will not respond to accelerator for the first 1-2 miles after a cold start, then runs fine, no check engine light has shown. Per shop recommendation switched to 92 octane x3tanks, then replaced fuel sensor, neither solved.
View 15 RepliesI have been getting no throttle response intermittently. I will be driving usually at lower speeds and all of a sudden the engine with slow down and there will be no response to the throttle pedal. It will come back quickly. Also the ESC light sometimes comes on and yesterday I could not set the cruise control. Today it had this problem but the ESC light was off and cruise control worked.
View 23 RepliesJust got the car back from the dealer a couple weeks ago after the engine was vibrating. Replaced one of the valves and it worked great. Now a few days ago I was driving home and the AC just flat out died. I know the 06's have a problem with the AC, but I think this is something different because the fan doesn't come on at all (with the AC on or off) either. When I turn the AC on, there is absolutely no response. RPMs don't go up as they would when the AC unit comes on, the fan doesn't come on... nothing. All that happens is the yellow light on the AC button turns on. The compass on my rear view mirror doesn't come on either. The turbo doesn't seem to kick in at all. If it kicking, it's very very weak. This all happened at the same time as the AC failure.
I checked the fuses, and everything seems to be okay. The console, for the first time ever, is saying I need to take the car in for maintenance in so many miles and in so many days. I've never gotten this message before. The car is 100% driveable though, other than the lack of power due to the turbo not coming on and not having AC in these hot 100+ degree days...
On my 86' 740 the cranking has been kinda lengthy and a bit weak as if the battery is going bad. I finally had an episode where the cranking and the start was stranding me. After three attempts and keeping the throttle wide opened it started. What is now strange is the crank is strong and faster as if something broke loose or got reset.

Intermittent accelerator problem: no response, just goes to idle. Runs perfectly with no other issues but zero response when the accelerator it pressed. There seems to be no pattern to the problem as this happens at any speed/position on the pedal. When the accelerator goes out the check engine light in the lower left corner comes on. All fuses are good.
Symptoms began a month or so ago feeling like an occasional 'hiccup' or hesitation. Symptoms occurred a few more times until a couple of weeks ago (Friday, 2/20/15) when it left my son stranded a few miles from home. He was able to limp it to a parking lot and we left it over night and went and towed it back to the house the next morning. The truck started and ran fine just no accelerator so we towed it idling so we would have power steering/brakes, etc. As we neared the house the engine light went out and the accelerator began working and he was able to drive the truck the remaining 1/2 mile home.
Most all of the research I did came back with the Throttle Position Sensor as the culprit. I was able to order one (the complete accelerator pedal assembly that is*) at a Napa store in a nearby town and picked it up on Tuesday (2/24). As soon as I installed it everything worked fine.
As an aside, I have read a lot about the mid-2001 switch from the units with the TPS (Throttle Position Sensor) and IVS (Idle Validation Switch) as separately connected units to the 'new' style where these parts are combined into one and there is a single 5-wire connector. Being a 2002 there was no question as to which one I had. Just be aware of the difference. Also, this part is simple to change. The connector has a clip that you pinch down on with your thumb and then pull off. I use my little electric impact with 1/4" extension and a 10mm socket. Zip, zip, zip an you're done. It takes me longer to get my tools out.
A few days later on Friday (2/27) it presented the sporadic accelerator symptom a couple of times again but was able to get the truck home. The next morning I unplugged, cleaned (CRC Contact Cleaner), and dabbed into the connector a small amount of dielectric grease to insure good connection. (I had read that in my research as well). That seemed to work beautifully and he said it ran fine all day and until the next afternoon (Sunday, 3/1) when it began acting up yet again.
I continued to research and could find nothing that would suggest anything other than the Throttle Position Sensor. I read that some other folks had gone through a few of the Napa/aftermarket units though so I began thinking that maybe I had just gotten a bad unit.
I have read many different threads regarding the TPS sensor on the pedal and EBPV deletes on the E99 7.3L Powerstrokes. I am trying to troubleshoot some issues with my E99 7.3L. Usually on cool mornings and after not being started for awhile the truck will seem to be stuck in an Idle. This is an intermittent problem that doesn't always happen.
I cleaned the connections to the Tps and the IVS sensor and put them back in. No luck. On another note I am also seeing a reduction in fuel mileage and power like the truck is being restricted. I don't know if these symptoms are related or possibly their own issues. I am troubleshooting and possibly thinking it is the EBPV system that isn't working correctly. Considering doing an EBPV delete with a NON-EBPV Pedestal and Flange.
I have a 2000 Grand Marquis. Yesterday I turned the key and the starter didn't crank. Everything else came on like it is supposed to. Radio, dash, warning lights, etc. After trying a few times, it started but the starter wouldn't disengage. I had to disconnect the battery for it to stop. I changed the ignition switch and cycled the key, but when I try to hook the battery back up, the starter immediately begins to crank. Even when the key is off and out of the ignition.

View 7 RepliesMy 2007 CM Santa Fe 45K miles began acting up intermittently. We have owned it 5 years from new and never any issues whatsoever. My wife told me that first thing in the morning it made a horrible clanking noise and the entire car shuddered so she shut it off. Then it cranked and ran for days normally. The other morning I got in it and cranked it and man, it sounded like rods knocking, pistons slapping the crank, it was awful. Actually it sounded like premature or off time detonation, the engine would not idle and would die.
After a couple more tries the engine cranked and ran smoothly but with increasing idle speed and after two instances of normal cranking but idle increasing ever upward (same morning in sequence of 10 minutes or so of trying) I called AAA and had it carried to the dealer afraid oil pump giving out, timing belt jumped, bad crank / cam sensors, who knows? Oil was changed 5K ago with Hyundai toilet paper filter.
Anyway dealer found a code, something about engine torque excess - who knows - it wasn't causing the horrible cranking idling banging noise... did some ECM/ECU update, and repaired a TSB for the passenger side Airbag seat detector. They kept it over night and still could not make it occur.
My wife is really worried because honestly it sounds like it's going to throw a rod or something *I know it doesn't have them*. It's just a horrible gut wrenching noise. Dealer mechanics could not find anything wrong and they kept it overnight to crank it cold, and when we picked it up today it cranked fine.... She can't trust it anymore.
I have a 2000 Hyundai Accent hatchback with 98k miles. About a month ago we were headed out of town and got gas about a mile away from the house. After filling up, the car wouldn't start. It would crank but not fire. Tried for about 15mins to no avail. Had it towed to local mechanic and it started right away. They kept it for the weekend and said they had no problems starting it, so without experiencing the problem they said they would just be throwing parts at it.
About 2 weeks after my wife drove to store and when she went to leave and same experience, but this time it started after trying for a couple of mins. Then just this Tuesday it wouldn't start in the morning. When it just cranks but not fire it shows a pending P0335 (crankshaft position sensor). So I ordered the part (won't arrive til Friday). When I got home I tried to start it as well to no avail; tried again Wednesday morning and evening, nothing. Then this morning (Thursday) it starts right up. Once its started it runs great. After recurrence of no start 2 weeks ago, I replaced spark plugs and spark plug wires.
1999 Savanna 1500 van. This has been a great Van, only has 70,000 miles and has never let me down until a few months ago in February when it was getting down to -20 degrees F. Seemed like it was cranking fast so I thought it was timing. Turned out there was no fuel pressure so first put the relay in, that didn't work so we dropped the tank and put a fuel pump in. This seemed like it cured the problem but I only drove it 200 miles until mid May when it did it again.
The security light wasn't staying on so we thought it must be the ignition switch. That didn't fix it either, we just got the ignition switch back together (not the actual switch but the wiring harness) and it's not starting again. It will start after some anguish and cursing at it. Seems like messing with the wires going to the fuel pump or hitting the cover over the fuel tank will cause it to start. I haven't checked it yet but I can guarantee it doesn't have any fuel pressure.
For the past year I have had intermittent start issues with my LS that occur about 15 percent of the time. Ambient or engine temperature do not make a difference. Sometimes the starter engages but then disengages right away. I then need to depress the start button an additional time or two before it actually starts. At other times the starter engages and continues cranking while the engine sounds like it is trying to start (like it is just barely keeping ahead of the starter speed). That carries on for several seconds and then it starts. Nothing shows on diagnostics and the dealer says I am going to have to wait until there is a complete "no start" before they can trouble shoot. There was a similar issue with earlier 460 models but the Lexus service tech said that problem does not apply to the 2011's. It seems there is a lack of fuel delivery but from what point? And why only intermittent and momentary?
View 6 RepliesRanger wont fire! fuel pumps not pumping..... Jumped fuel pump relay and got both pumps working, but while jumping relay and cranking motor, still no fire. Plenty of fuel pressure though. got spark too. Replaced relay and no pumps working while key is turned to run or while cranking. I got to get this sweet puppy back on the tarmac...
View 7 Replies2006 F250, 6.0, AT, 59K. Week and a half ago, started cranking slow. I charged the batteries and checked with a professional load tester. Both batteries good, but voltage was fluctuating and tester said charging system needs service (no battery light). I swapped in a remand alternator as a new was not available that day. It lasted 6 days and this time the battery light was intermittent.
I checked voltage and again it was fluctuating. I swapped in another remand unit and 3 days later, same thing, intermittent battery light and fluctuating voltage. I'm installing a new, not remand unit tomorrow. However, could a bad FICM cause this problem? I noticed that the engine seems louder (not the exhaust note) at idle. This truck is clean and I have no corrosion issues. What is the right direction to test the FICM?
My dashboard turns off . I have it disassembled and redo all welds. But nothing changed. However, disconnecting some lamps, it light on . Do you think that can come from L4925N ?
View 1 RepliesI have a problem with my 1994 Volvo 940 GL. When I turn on the headlights (light knob pointing to the right) the headlights do not come on, the rear lights aren't on, the dashboard lighting turns off, etc... I don't know about the brake lights, i bet they work fine...
What's odd is that if i set the knob to the middle (pointing up), the rear lights come on, dashboard lighting works, and front-side lights come on as usual. In order to drive at night, I have to set the knob to the middle, and hold down the brights (which work fine).
My 740 (1990, B230E, non-turbo) has been running rough at low rpm. Once above 1800 rpm or so it's fine. I've changed the Distributor cap and rotor arm (they were both shot), but the problem persists. I'm thinking injector relay or ignition stage amplifier next, but I don't want to just through parts at it.
The plugs were changed 3 months/1,500 miles ago. The misfire is intermittent.
I have a vibration that comes and goes at a regular interval. Starts at about 60+ MPH on up. Most apparent between 70 & 75 MPH. The steering wheel will visibly vibrate for about 3 seconds and become completely smooth for 1 to 2 seconds. This vibration interval repeats over and over, in Drive or Neutral. I have replaced both outer tie rod ends, driver side wheel bearing, L & R stabilizer bars, rotors, pads and calipers. Passenger side motor mount which was visibly broken, others all ok. Finally, I just replaced both axle shafts with brand new ones. Front tires are in balance and round! At lower speeds, 60 and below it is smooth as silk. Bumps sound good, no rattle noises or loose sounds. No pulling left or right.
View 2 RepliesI've checked the wheel bearings, lug nuts and wheel balance. Sometimes the car will shimmy or vibrate not in the steering wheel and not all the time. It will vibrate for a day or two, then nothing, then vibrate again. It was not vibrating today, then I took some curves hard at 35 mph or so and it started a medium level vibration. This vibration started a day or two after the ABS, traction control, and check engine lights came on while nearly completing a 10 hour drive. I have described this to a number of mechanics and the fact that the vibration goes away has them stumped.
View 8 RepliesMy 1996 Volvo 850 has a relatively new battery but every few weeks it will go completely dead. A typical situation is this: the car will start fine and we will go to a restaurant but when we come out the battery is so dead that the digital clock is off and the radio pre-sets are lost. The shop has done a lot of diagnostics and replaced the alternator but the problem persists. They have determined that the battery is fine and the current drain when the car is off is within normal specs. And, yes, they have disconnected the light in the glove box. They have done everything they can think of but because the problem is so intermittent it is proving impossible to track down.
