1994 ford f250 7.5 I have replaced thermostat to a 185 from a 192 new fan clutch dam truck still gets pretty hot at idle or if I am at a stop light and fast It shouldn't run this hot. It gets to 95 degrees never had this problem before only thing I can think of doing Is a radiator flush and clean it really good have checked for obstructions in fins but clean.
View 2 RepliesI have a '95 Ford F150 with a manual transmission and when I come to a stop light, the engine will either idle down more then it should then go back to normal or it will idle down and then stall out. And when I accelerate, I have to gun the engine for it to go forward or it will stall out again. I replaced the fuel filter and cleaned the air intake area and it still happens.
View 2 RepliesI posted a few weeks ago about a problem I fixed with the MAF ( leak after the MAF ). 89 GT 111k miles, ( car restored to showroom condition ) Last week I pull to a stop light and idle is at 2000 RPM. Shut engine off and restarted and all was well, and idle back to about 800. I know something was wrong before hand as the car was pulling without my foot of the throttle. This happened again when I pulled into my driveway so let it run like this and when I pulled the plug on the IAC and idle dropped to about 600.
I took the IAC off the TB and cleaned it which did not look too bad. Installed IAC but left it disconnected and set up the idle on the TB according to the shop manual to 750 RPM. Shut engine off connected the IAC and followed the instructions in the manual to reset the ECU by disconnecting the battery for a few minutes, letting it idle for 2 minutes shut engine off then restart.
Well it was good for 2 days then started the same thing, 2000 rpm at idle..for the time being I have the IAC disconnected and set the idle up on the TB to about 850 RPM.
I have been driving the car like this for 4 days now and no running problems what so ever. Funny thing is no check engine light and no stored codes during this entire episode..Had my friend with an earlier OBD scan for codes and clean.
I hate shot gunning parts by replacing the IAC. Does it hurt running the car with the IAC disconnected or should I foot the bill and get a new one ? and hope that is the problem..or could something else be causing this ?
I checked for any vacuum leaks using my propane torch no change in idle. IAC problem on 89 Mustang GT 5.0 manual trans.?
1997 escort lx wagon, manual, 173,000 miles... When I stop at a red light or stop sign, it takes 10-15 seconds for the idle to drop down to where it should be, and when I push clutch in to shift gears it doesn't drop down, it stays where it is. No codes are coming up. I'm thinking IAC....
View 9 RepliesI have a 2005 Ford F-250 Powerstroke. At times when stopping at light or for any reason, I give it gas but it does not want to go. It's like it is not even registering that I am pushing the pedal. I shift it into neutral and rev it up then switch it back to drive and it goes and puffs out smoke. What is going on?
View 6 RepliesI have a 2003 ford Explorer xlt v8 4.6 with a P2197 code.(02 sensor bank2 sensor1)...
I had code P2195 a few months ago and replaced that 02 sensor but just recently truck threw code P2197 and is now starting to idle surge when I stop at a light or just leave it running in park.
Replaced PCV valve and the hose that goes from pcv valve to IAC also replaced Fuel Filter. Cleaned IAC, Throttle Body and MAF did the old check for vacuum leaks with can of carb cleaner nothing found.
Pulled all coil packs off checked OHMs all read .6,coil boots looked to be in good shape going to replace spark plugs and 02 sensor.
2001 f350 v10, initial problem was when i came to stop at light it idled rough. I changed all plugs,injectors and COP, and bad connectors thereto. Changed the clock spring as well. Now the truck idles like crap at first start of of the day then run fine there after. Replaced IAC, TPS, Temp sensor. Condition getting worse and now the temp gauge does not work. I am thinking maybe CAT Converter loaded up?
View 2 RepliesI have my 2004 f250 6.8L. Recently my truck has been having issue with the oil needle. When im stopped or coming to a stop my Check Gauge light comes on and my oil needle drops all the way down. As soon i step on gas it goes right back up. What could it be?
View 7 RepliesAm I the only one who thinks the tire pressure monitoring system is a silly feature? Is there any way to delete this and stop the light from coming up on the dash? I want to do new wheels and tires on my 2008 f250 and I don't want to deal with the tpms. Can it be tuned out from the computer?

View 5 RepliesWithin the past few days my towncar has developed a rough idle. When I'm stopped at a light or stop sign it jumps and just plain idles rough. This also happens when I change speeds after either accelerate or decelerate. I travel an average of 80 miles a day total to and from work and my car has about 140,000 miles on it.
View 13 RepliesMy car is a 2010 gti mk6, unitronic stage 2, apr turboback, r8 coilpacks, stock intake with k&n drop in filter. Several months ago, it started throwing CELs, P2096 post catalyst fuel trim system too lean bank1. I cleared it. It kept coming back. Sometimes it threw P2293 fuel pressure regulator 2 performance but I read it via VCDS, it should be P0088 Fuel Rail/System Pressure too high - intermittent. it was accompanied by some high idles at stop light e.g. at constant 900, 1000 or even 1200rpm occasionally. but the car drove well, seemed like nothing wrong.
High idle youtube link: [URL] .....
I changed the front o2 sensor but the problem persisted. Then I thought it was the MAF, I unplugged it, oil consumption improved but high idle and the above P2293 persisted. Recently, the high idle appears more frequently. I now suspect it is the PCV valve. I took off the oil cap this morning, felt some suction, the engine shakes a little and exhaust sounded a little rough but rpm didn't change. Taking off the oil dipstick showed the same. Is it the pcv valve?
I disconnected the battery yesterday and once I connected it back the car felt like it was gonna turn off and ever since when I'm in a stop it starts shaking. Is their anyway to fix the idle time ....
View 7 RepliesI'm trying to diagnose the problem with my friend's 1994 crown Vic police interceptor. It dies at stop signs and then won't start back up till after waiting like 5-10 minutes. I asked him if his check engine light is on. He said yes, so I looked up how to retrieve the codes with a jumper wire as I have on older vehicles of my own. I found that information but can't locate the terminal. He said other symptoms are poor fuel economy and sluggish performance. My friend is so busy and pinched for cash he's been driving like this for over a year.
View 1 RepliesThis is my brother's 02 SE. 140k miles. 4cyl. He claims that the car is beginning to idle rough when he is stopped at a stop light and the AC is on. If i replace the spark plugs should that do it? I'm pretty sure it doesn't have spark plug wires cus that's what my dealer parts dept said. Motor mounts were replaced around 70k if that matters. The vibration is directly related to the AC being on.
I am also going to replace the serp. belt because there's a belt squeak when the motor is cold.
Have a jazz blue chipped tuned with giac.. It does this random times.. When I come to a red light on idle the rpms go up and down just a bet but never stalls. The car vibrates and the engine shakes a bit. Engine is stable when car is on and off. Idk if its motor mounts or what?
View 10 RepliesI have a santa fe from the year 2008 and recently i had a trip where i would get tons of white smoke every time the car was at idle at the stop light. upon inspection, i saw that the coolant level was below the low line so i had it topped up and the problem disappeared. Everything was fine until today when the problem occurred so i checked the coolant level on the side of the road but the coolant level was fine and still is upon inspection when the car was cooled off. After i stopped to check the coolant level and restarting the car, the smoke was gone and did not appear again. I checked the internet for solutions and some suggest blown head gasket but many of the symptoms do not make sense in my case since the engine never overheats and the coolant level hasn't gone down in the past week.
View 3 RepliesI have noticed, in my 2012 Elantra with 32,000 miles on it, that my car is shaking at idle. I'll be at a red light or stop sign and the vibration is SUPER annoying. I have had it tested at a Hyundai Dealership. They couldn't "replicate the problem" and nothing it wrong with my car.
I may be trading this car in for the Veloster Turbo. I'm tired of how slow this car is. I know I sacrificed speed for gas mileage, but I have a question, does the Veloster have this problem as well?
My 2002 passat engine shakes when in idle or stop at light. When running on highway, it is smooth. what could it be?
View 3 RepliesI have a 2002 Honda CRV that recently started to fail on me. I'll be driving and usually in front of a red light (when the car is idle), the car will stop. Luckily, the last time it happened, I was able to get the car to start back up again. Also, the car sometimes won't start (ignition won't start) from when it's been parked. It happened multiple times this past week and the mechanic apparently doesn't know what it is. He cleaned my throttle body, how smooth my car runs now (less shaky) but the problem still persists.
