When I fire her up, the AC will blow cold for 10ish minutes until everything is up to normal operating temperature. Then it tends to blow warm, and that last for about 20 minutes, before finally settling back down and being cold AC again. I initially thought it was an issue with my compressor disengaging, but it doesn't seem to be...
View 3 RepliesMy A/C will blow cold for about 3 min. and then stop for 10 min......then cold again for 3 min.....then warm for 10 min.......what is going on ? It does this when on climate control and on A/C . I had a compressor go out about 1 1/2 yrs. ago due to a fan failing...the compressor tore apart... This is not acting like that though .
View 9 RepliesI have replaced the EGR over 1 month ago and also replaced the MAP sensor also as it was bad. I also have a Scan gauge, for monitoring.
The problem is once the truck gets to OT and the valve opens I have heavy black smoke on take off?
I have a 2007 F250 6.0 L with 116000 miles. I have never done any modifications or changed anything on the truck. Now that the weather is starting to warm up I've noticed that once the truck is at operating temperature it starts to chug and sometimes even die while driving and while its doing this the truck has no power. It does not seem to do it when its cold. Here is a picture of my gauges KOEO operating temp at idle...
View 4 RepliesThe other day, I started having problems with the truck not starting when at operating temp. Went for a drive and stopped a a scenic overlook, and spent about 30 minutes taking pictures. Went back to the truck, and it wouldn't start. Outside temp was about 95 degrees.
I tried for about half an hour to start it, but all it would do is turn over. There was a work crew there with their heavy machinery, and I was able to borrow their starting fluid. One quick squirt into the intake, and it fired right up.
Although I do have an oil leak from the right valve cover, when I checked the oil, it was just off the full mark. The truck was parked on a slight angle with the driver side being about a foot higher than the passenger side.
2003 F350 w/6.0, 180,000 miles
I have a 04 f350 6.0 with about 195xxx miles on it. The other day my truck started acting up. It starts and idles without a problem and drives fine till the engine gets to operating temp once there I cannot accelerate quickly like getting onto the highway to get up to speed it just the motor just goes quiet and won't accelerate. It usually does this a little after 2000 rpm. I can let off the throttle and slowly get to speed as long as I don't go past 2000 rpm. No check engine light was not on scanned it and got p0611 for the ficm. I tested the ficm and it read 48v with key on. While truck was running I got 46.xx v then Started to climb to almost 48v. The truck was warm but not at operating temp where the problems starts(didn't have time to let it warm up all the way) could these symptoms be the ficm still? What else should I test?
View 5 RepliesI have a 12 cc 4x4 drw. I hauled a bull and a cow about 100 miles this morning. I was pullling approx 6k including the trailer. The temp was about 75*. 50-60 miles into the trip I switched to the oil temp screen and the oil temp was 224* and the trannie was 199*. I was going into the wind which was about 20 mph, and I was traveling 75mph. The truck never lugged down heck it never shifted out of 6th gear. When I unloaded the cattle the temp came back down around 190*. Headed home and the temp got up to 226* and the tranni went to 205*. This was going with the wind and just the trailer. I am using oem 10w-30 motorcraft and motorcraft filters. The truck just has 9k miles on it. I am thinking that the oil temp is a little warm, should I be worried. What should I look for to diagnose. I like to do my own diagnosing if I can, the dealers around me can't find anything wrong even if you point the leak out to them. Should I be using a different oil?

View 1 RepliesI know that average normal tranny temps for the new 6.7s are 200 degrees give or take which my truck does as well. but I'm wondering about how long is normal for the tranny temp to get up to that normal range? My truck can take anywhere from 20 minutes to almost an hour depending on if I'm on highway vs lower speed driving and it's been that way since I bought it. Am I worrying over nothing or my worries not just worries?
View 7 RepliesI have a 2001 Miata. It's been over 100 degrees daily lately. The AC will blow sort of cold for about 30 minutes and the temp gauge will move towards the H hashmarks. If I turn the AC off, the gauge will slowly drop. I've also noticed that the amount of cold air is decreasing as time passes. In fact, the other day, the system was blowing air hotter than the outside temperature after about an hour drive.
The viewing glass has bubbling stuff flowing thru it. The recently flushed radiator is full as is the overflow reservoir.
I have a 2004 Grand Prix and it is displaying the symptoms of overheating but the temp gauge is not going above normal operating temp. I replaced the thermostat twice, and after driving for about 10-20 mins coolant comes out of the overflow. I'm at a loss, I'm thinking temp sensor(?) But I don't want to keep throwing unnecessary money into it. The fans work fine, the heater blows as it should.
View 8 Repliestoday me and the wife where riding around doing some things before the snow storm. we went to the store and the heat was great but when we came out cranked the truck and all of a sudden no heat at all would just blow cold air. im not trying to go to a dealer and get charged an arm and a leg so where do i start.
View 14 RepliesI have an 03 f250 6.0 150k milage and lately my A/C has not been working at its best. Its intermittent, and for some reason it will work fine until i get on the highway and it just blows hot air. Would this be a leak or clutch issue? One thing I have noticed if my oil/coolant is above 200 the A/C will blow hot air but not return to cold when the temperatures return to normal. I haven't done any trouble shooting so my first thing ill check are the fuses. As far as the compressor goes its an alien object to me I have never had A/C issues with any vehicle i have owned.
View 6 RepliesI have a 2007 6.0 that this has happened to twice now. It's fine around town but I never hear the can come on. Friday when on the interstate my my temp gauge started to rise past normal operating temperature before fan came on. Is this normal? After the fan came on it stayed at normal temp for the rest of trip....
View 5 RepliesI'm having a bit of a cold start issue, need to know if it is normal or something is wrong. I live in southern Indiana and it's gotten down to a VERY cold 50 degrees (lol) and the past two mornings I have started it up and it seems to have a misfire first thing in the morning and it will kick into high-idle mode and after I shut it off and start it back up about 20 seconds later after the ECT gets above 100* and it runs perfectly. It has brand new 190/100 injectors from Warren, an IDP tune, and I am running 13 quarts of FoMoCo 15w-40 oil with 2 quarts of hot shot stiction eliminator (tried it before installing new injectors). And also throwing no codes. Is this normal or should I be looking for a problem?
View 13 RepliesOK, long story short. I had P2284 code on my scan gauge after replacing the oil cooler. I contributed it to air in the oil system. Sure enough, a few days of hard driving and the code went away.
Now a week later, I fired up my truck on a cold start yesterday morning. It's not that cold here(low 40's in the morning), but the oil started off at about 50F. Correspondingly, ICP at is higher, at around 1000(it's like this every morning until oil warms up). I usually let it warm up a tad before driving but yesterday I didn't, and hit the gas pedal a little hard once and the truck started acting like it does when you get this code.
Sure enough, check scan gauge and the code is there. I drive home(about 15 minutes). A half hour later I start the truck up, check codes, and it's back to normal. Of course, oil temps were higher and ICP in the normal range between 580-590.
So is this normal? Since it doesn't trigger a CEL I assume it's more of a system parameters code? Only other thing I can think of, if this isn't normal, is a mucked up IPR screen from when I installed my BPD oil cooler.
I don't have my manual handy, wondering what the normal operating temp of the coolant is for a 1.8T B5? I believe it is 190, but want confirmation.
View 1 RepliesAbove 0 Cel.(32F.) 145 F-165 F. even in summer towing. Winter when it gets -20 my trans temp gets warmer (not towing 165.F or higher) When it gets to -30 my trans temp gets to 175 F. or higher I have never looked at trans temps before on any vehicle that I have owned. I like that these trans get warmer when it is cold out and colder when it is hot out.

View 1 RepliesI've got a 1997 Nissan Altima (automatic, GXE). Recently it has started stalling. Usually this happens when the engine has warmed up to normal operating temperature (though last night it happened when the engine had just started).
Usually when it stalls it will start right back up, but sometimes it takes a few minutes. Sometimes it will start back up and die right away, other times it will turn over and over but not start. After a few minutes it will start back up. Sometimes it will stall momentarily and then restart right away, but not usually.
The rest of the time the car runs smooth as ever, no surging, no stalling, no erratic idling, no sputtering or anything. Usually the check engine light will come on after a stall, but I get a "no code" code when I check.
This started about two weeks ago, it did it once on a Saturday and then didn't do it again until Wednesday. Since then it has happened at least once a day, and yesterday it happened a lot while I was driving home, but not at all when I headed to work. Today it was fine for about 15 minutes and then started doing it a lot, but the last 3 or 4 miles it was fine again.
What may be the problem? I'm going to check the MAF and throttle position sensors, though I would assume if they were malfunctioning I'd either have more symptoms or I'd be getting a code.
