Toyota - Corolla :: At Idle Car Runs Very Rough But Can Accelerate Up To About 50 MPH
I have a 2000 Corolla with about 147,000 miles. At idle it runs very rough, but can accelerate up to about 50 mph. Then it starts to cough and wheeze and run roughly again and won't accelerate any further. It feels like the engine will shake itself off its mounts, so I slow down and stay under 50 mph. I replaced spark plugs and a repair place hooked it up to a computer. They then told me it needed about 1800 dollars worth of repairs to replace the valve cam I think they said. I'm skeptical and wonder if it just needs a tune up, . It has not had one since I bought it at 128,000 miles, and II don't know how long it had been prior to that.

I was driving yesterday and my Toyota pickup started losing power. If I let off the gas at a stop it would rapidly die. I managed to get it home but had to floor it just to get it going in 1st and 2nd gear, and if it was in neutral it would die without giving it a lot of gas. The only way it will start is if I give it a lot of gas while turning the ignition, and have to keep the RPM's up to keep it running. Looked under the hood while it was running and when I let off the throttle the entire motor would shake violently. Cant tell if it's just not getting fuel correctly or if it blew a head gasket maybe. Seems like it might only be firing on 2 or 3 cylinders.

Mine is toyota corolla - 2001 VE model. It has 116K miles in it.
It hesitates nowadays to pickup after a long idle time, say in morning when i start to work or when i leave from work to home(idle time of 8 to 10 hrs). I noticed this problem only during very high temp, say atleast 80F.
Hesitation will be there for 4 or 5 secs and will not move even if i give full acceleration, but after that it moves normally.
Car has automatic transmission and i only see this i put it to Drive(D or D2) and not when i do reverse.
Toyota - Pickup :: 1991 V6 Overheating At Idle And Cool Down Again Once Began Driving
I have a 1991 V6 automatic Toyota pickup. The transmission has ~230,000 miles, but the engine has been rebuilt and probably has less than 5,000 miles on it. I am having overheating issues in both departments.
Engine overheating: This has started fairly recently. My truck began overheating at idle (usually at longer traffic lights) and would cool down again once I began driving. My coolant was low, I took it to a shop, and they fixed a small leak. Fast forward a few weeks and it happened again, and this time when I turned on my heat full blast to take heat off the engine it blew cool air until I started driving. Took it back, they found no more leaks, and couldn't duplicate the overheating symptoms. They also said the fan and thermostat seemed to be working fine. It seems to happen sporadically, regardless of coolant levels.
Transmission overheating: Firstly, my truck tends to delay/hard shift when I first start it in the morning. Once the engine warms up it goes away for the most part. I took it on a 100 mile trip camping on a fairly curvy/hilly forest highway and the A/T Oil Temp light came on. This has happened before when I took it on forest roads, even after a recent ATF flush. Needless to say I had to stop a few times to cool it off. It felt like the transmission was working too hard at a flat 60MPH (2,500-2,800RPMs). A couple times the RPMs were pulsing like it was switching gears back and forth. The next day driving in town everything was back to working order.
I'm not sure if these two things are connected... but they never happen at the same time. I'm taking it to a transmission shop but I want to make sure they don't try to rip me off unless absolutely necessary.
Ford F-150 (2004-2008) :: Backfires / Spits And Sputters - Rough Idle
I've recently replaced the timing chains on my sons 04 F-150 5.4. Now I'm getting a code PO174. I've changed 2 coil packs, fuel filter, MAF sensor and cleaned all the connections. Fuel filter had what looked like brown fuel coming out of the in line of the filter. I'm stressed out now, the truck does not even have enough power to drive up the driveway. Backfires, spits and sputters, has rough idle.

I'm working on a 06' Passat 2.0t and it runs rough only at idle like its misfiring only vag-com says no misfires and no engine codes. MAF looks like it may be a little low on performance but should be ok. I tried swapping out coil packs but no change. I changed the pcv breather and hose, cleaned the carbon off the valves, swapped the throttle body with a known good one, and changed the piston on the fuel pump and still no change. It smooths out when I turn the a/c on but that's the only thing that changes the idle.

View 10 RepliesAstro - Chevrolet :: 1997 - Runs Rough At Idle
I've taken it to a half dozen mechanics, none can diagnose the problem. From a cold start the engine idles well, but once it warms up and the fast idle setting shuts off, it begins to vibrate quite a bit. I rebuild that included an all new fuel injection system, new ignition parts (including distributor, replaced at a later date,) new wire to alternator (the old one had cracked insulation,) and a new mass airflow sensor (swapped in from a parts van-no effect.)
Basically everything is new except for the sensors (crank sensor, idle air, throttle position, etc.,) and the fuel filter and pump. I'm not getting any codes, and at least two mechanics said it had good fuel pressure. It FEELS like a vacuum problem on a carburetor vehicle, but I had the vacuum harness checked as well, and everything seems to be in order.

View 2 RepliesNissan - Maxima :: 1998 - Runs Rough Once It Warms Up - Doesn't Idle Well
My 98 Maxima won't idle without dying, it sputters when you accelerate, and it tries to die while coasting. I've changed two O2 sensors (AutoZone gave me the code for bank 1 sensor 1 & 2) changed spark plugs, tried fuel injector cleaner, oil change, and cleaned MAF sensor & checked the wiring. It;s still spitting out the black exhaust. Although after changing the O2 sensors it quit for about a day or two but started again (I'm guessing the other sensors need to be changed to) But the main problem is once it warms up, it really runs like crap, and is a major gas hog. I'm getting about 12 Mpg.

My 2002 Toyota Camry 3.0L EFI DOHC 6cyl Camry LE will periodically refuse to go into overdrive. When I pull the code it shows P0330 code. (knock sensor bank 2 failed knock sensor/fault in knock sensor circuit/failed PCM) It seems that if I clear the code the problem goes away and the car shifts smoothly for about 30 miles and the then go right back into the problem. (and the code shows back up.) This makes no sense to me and I don't see how the 2 might be related? Is this just a coincidence or am I missing something? The Over drive switch indicator light goes on and off when I push it on and off but does not work with the problem when it is occurring. I just did a transmission service on it last week end and had done one 35000 miles ago. The car has 220,000 miles on it.

Toyota - Corolla :: 1981 - Won't Start When Hot?
My 1981 Toyota Corolla wagon began to intermittently fail to start when warmed up about five years ago, and by fail to start I mean all lights come on but zero crank and no clicking sounds either. The amount of time I must wait for it to cool down and start again has varied between 20 minutes and today's record, 3 hours. This problem is common with older Toyotas and usually means the starter motor needs to be replaced, believe me I've looked into it, but here's the puzzler. I've replaced the starter motor two times and it has failed to solve the problem. I've replaced the ignition switch four times, same thing. I replaced the battery thinking maybe my old battery was losing mojo, but tears came to my eyes when it happened again.
I've studied how a hot starter head close to the exhaust manifold sees it's resistance go up, that the initial crank requires big voltage throughput. But an aluminum heat shield is built in and wrapping the starter in a heat blocking blanket is not physically possible with my configuration. What I haven't looked into yet is the clutch safety switch. I did receive the following bullet from a previous CarTalk query which read: "If a manual transmission, the clutch safety switch must be working and have low enough "on" resistance. Likewise with an automatic transmission, the neutral safety switch." I would love more detail about the clutch safety switch. I can add this interesting caveat to today's 3 hour record wait. I've gotten good a bump starting the car by myself. Today I bump started it in rolling reverse, re-parked it, and tried restarting again. Started right up when it wouldn't start moments before.

View 5 RepliesToyota - Corolla :: 1981 - Cranks When Hot Only Starts When Cool
My 1981 Toyota Corolla wagon is beloved but developed a problem wherein when it gets warmed up and it is turned off, it may not start again until it cools down. When I say start I mean no crank, the starter will not turn over. All other electrical functions continue to work. The required wait is usually about 20 minutes and it will start again. I replaced the ignition switch in my steering column about four times (why four is another story) and the problem persisted.
Web research indicates the starter motor should be replaced, that because the starter is close to the exhaust manifold it can get quite hot and the phenomenon is called 'heat soak' where the electrical conductivity within the starter becomes overwhelmed by the heat, raising the resistance to the point where it will not conduct adequately. But I just replaced the starter motor and the problem is still the same! I am quite perplexed. I was so sure that would solve it.
Ford Super Duty (1999-2016) :: Rough Idle And Stalls But Runs Fine At Higher RPMs - No Brakes
Let me start with I have a 2003 f250 5.4. The motor blew on my truck and I had a 100k motor dropped in it. I've put new spark plugs, ohmd out the coils. I tried both sets of injectors. cat delete and new fuel pump. It has rough idle and stalls but runs fine at higher rpms. Also has basically no brakes. I am thinking vacuum but I've check all the lines. No codes either!! also cleaned throttle body.
