View 12 RepliesFord - Escort - Code :: 1443 - Service Engine Soon Light Popped Up
Last year my car popped up with the SERVICE ENGINE SOON light. I am cheap so I went out and bought a code reader- code 1443 came up. Online I found this information: 1443-Evaporative Emission Control System - Vacuum System - Purge Control Solenoid or Purge Control Valve fault. I bought something from Ford for $81, erased the code and it came back on a week later. I just kept erasing it. It quit coming back on in November so I figured the bulb had burned out but the Light came on when I started the car. So I just ignored it. Now that the weather has warmed up again the light comes back on with the same code. Other question. Are there any modern cars that are as easy to work on as, say, a 68 Falcon? Or even a 74 Pinto? I don't expect real ease I just want to be able to stick my hand in the engine compartment with a blood sacrifice.

View 3 RepliesFord Ranger / B-Series :: 2000 - Idle With Code PO171?
2000 ranger 2.5 stick, coming to a stop i put in the cluch and the motor speeds up then slows down sometimes more sometimes less.
A month ago I had a code PO171, with a good idle. I cleaned the MAF senser then cleared the code, a week later the the CIL came back on same code. Then a month after the CIL is on the engine idle problem started. So I recleaned the MAF with MAF cleaner, cleared the code, and replaced the ICV with a new one. That worked good for about 3 days now the idle problem is back again.
The idle problem seam to be worse when the motor is warm or has been running at freeway speeds.
Toyota - Corolla :: 2000 - Check Engine Light Reading PO171 / PO172 And PO420
My Toyota Corolla 2000, 123,000 miles, Mass license plate, still getting 34 miles per gallon, has had check engine light on and off for a year.Failed inspection this June.
First garage in Somerville, without doing more than getting the three readings above, said catalytic converter was needed $350 plus labor.I was unable to do the work then and returned to NYC and job. Took to another mechanic recently to get fixed (as I wasn't returning to Mass for a while)and got only PO 171. I mentioned the other readings; they kind of scoffed it off.Trying to save me money (I guess), they cleaned the MAF filter and fuel ejectors for $200. Looked like it was fixed. A week later check engine light came on again and when I brought in found the PO 420 reading. They did not tell me if other computer read-outs were coming up as well.
Now they want to leave the oxygen sensor in front but change the one behind. Put in a newcatalytic converter $539 {they had quoted me $238 but it wasn't an OEM one I guess and they said they wouldn't warranty anything but this expensive one), charge me$137 for the oxygen sensor190 laborplus taxfor a total of a whooping $946!
I am afraid they will do this very expensive job and the check engine light will come on and htey will say o its something else.how can i be sure? also I was reading for a catalytic converter to go bad, something has caused it...what would that be? how to find out. Do they need to do the diagnosis with gas analyzer etc?
Why I spend a huge amount for an old car that is running well, not losing gas mileage, but perhaps is a bit slower on power.

Does the 2011 6.2 have a DPFE sensor? If so where is it located? Codes are lean bank one and two and random misfire. Suggestions I have read online are replace DPFE sensor. I don't think maybe there is one on a 2011 6.2. Who have had it and had it fixed. Other things I see are clean the MAF sensor. Look for vacuum leaks.
View 1 RepliesFord Ranger / B-Series :: 2000 - Code PO171 - Intermittently Coasting At 20mph Out Of Gear
2000 ranger 2.5 245000 miles. code po171 and idle problem has come back. Replace ICV, EGR, MAF, PVC, check fuel pres, air cleaner, plugs, wires, O2, check for vac leaks, Intermittently coasting at 20mph out of gear (stick shift) engine revs to 2500 rpm and holds until i brake to a stop then it idles down. So I disconnect the ICV and it runs perfect. (its a new ICV) something is telling the ICV to open up. a month ago it did the same thing when i replaced the EGR the idle problem cleared up so I thought that was it.
There is a relationship between the truck speed and the engine speed but how does the engine speed know the truck is moving when its out of gear. It work perfect for a month all of a sudden it starts this problem again. I am thinking of taking it to the ford dealer for a diagnostic test but I don't know how specific they can get on whats wrong I don't what to them to just say "oh you have a vac leak" . . . I know a 171 could be vac leak but the problem is so dramatic and off again on again it seems more like a part problem then a vac hose is either leaking or not.
Ford - Escort :: 1999 - Randomly Stalls When Stopping At Red Light
I've got a 99 Ford Escort Se 4 door sedan, Automatic trans with about 140k miles on it that randomly stalls when stopping at a red light. It is random and rare, but it does happen.
When it stalls, it sounds and feels like something is mechanically stopping the engine, like maybe it's not disconnecting from the automatic transmission. I can hear the engine working hard as the car slows down, it jumps around in the engine compartment a little bit, then dies as the car comes to a complete stop.
Then I start the car back up, everything is back to normal and I drive away with no further problems for the rest of the trip.
What can cause this? Does this car have a TCC clutch in the torque converter? Is it maybe randomly being falsely triggered to apply at low speed?
GTI 337/20th Anniversary :: 2004 1.8t GLI - Lean Code PO171
I got a 04 mk4 gli 1.8t and I got a po171 lean code and I know it could be a vacuum leak the maf sensor and other things. But when I clear the code it takes a couple days for it to come back on. But when I do clear it and start the car for the first time the car idles read bad almost sounds like miss fire. The when I pull out it hesitates just for a little than runs fine. Could this be a bad or dirty maf sensor? Like I said it takes a while for the cel to come back on.
View 1 RepliesLincoln :: 2002 - Idles Wildly / Getting Code PO171 And PO174?
My 02 navigator does not idle right when in park or sitting at stoplight. I've gotten codes po171 and po174. The truck ran fine for a good 3 months after the (service engine soon light) came on and I got these codes so I decided to do nothing.. Now it idles bad and has even shut off twice on me while pulling into driveway. I changed the MAF and that did nothing.. Should I assume its the o2 sensors or is there a chance my CAT is shot.
View 2 RepliesEngines - Camry :: Stalled When Put Car In Reverse To Downshift - CEL Code Reads PO171
While driving in a storm over the winter, I hit a skid and reverted to my old days of driving on ice (in a different stick-shift car). I tried to down-shift our '98 Camry (automatic)....so I placed it in reverse. It stalled. The car continues to run, but the check engine light has been on since that day.
I took it into a nearby garage the next week and they couldn't find any engine issues that time. They turned off the check engine light. It came back on the next day. I went to Advanced Auto Parts and got the code read: PO 171.
Since then, I've been driving the car once or twice a week, saving up $$ before taking it to my new repair shop -- to which we've switched for our other car. What might I expect to hear from them about our Camry? Am I damaging the car by continuing to drive it?
Ford - Explorer :: 1999 - Check Engine Light Keeps Coming On / Misfire Code
I have a 99 Ford Explorer - w/217k miles. (2nd owner) .. I got an oil change 3 weeks ago, tune up 2 mos ago, and new brakes/tires within the last 6 mos, oh, and Brother-In-Law just recharged my a/c last week.
Runs well, and I hope to keep it for another few years, but having problem lately.
Check Engine light keeps coming on - I've taken it in, and they read the code, and it comes up with a misfire. Mechanic resets it, and it will stay off for a few days/weeks, and then comes back on.

View 6 RepliesFord 7.3L Power Stroke (1999-2003) :: P1211 Code With Constant Service Engine Light
I was on the way back from the weekend trip and got a service engine soon light. I didn't notice any lack of power, rough idle or hard starting cold or hot. So we pushed on home. I checked the codes and it is the P1211.
Doing some research it seems the ICP is not as expected so I hooked up my phone with the Torque app and the IPR and ICP seem to be close to normal at idle and running. I din't see any high IPR %.
At idle the IPR was around 15.5 cold and 10.1 after a short run to the store and back when it warmed up a bit. ICP was around 690-720 cold and 470-490 when i got back.
Does that seem like normal readings? I cleared the codes and the CEL comes back on right away after starting the truck. I do have a TS performance chip that I will take out and see if that could be causing any problems. What else should I be looking into?
Ford Super Duty (1999-2016) :: F250 - Check Engine Light Comes On And Code P0500
So yesterday I decided to wash my truck and after taking care of that I took it for a short drive and the tranny started acting funny. Check engine light comes on and the code is P0500 . It calls for a VSS but I cant locate it. Also the fact that it did after washing the truck is making me think its a wiring issue... F250 SD 5.4 4x4 ....
View 5 RepliesFord - Escort :: Code P0455 (Gross Evap Leak)
Car has about 75K miles. Son has the car out of town (again), at school. He reported CEL (SES?) light on; "what should I do?" Told him to have it checked. He has trusted mechanic nearby, so I told him to go there. They say they don't just read codes ("You can get Autozone to do that"); they do diagnosis.
Report: Code P0455 (gross evap leak). Did smoke test; nothing. "Did you maybe have it running when you filled gas tank?" (No.) They reset the CEL, and sent him on his way.
Should we be satisfied if CEL stays off? What else to try or to look for if same code comes back?
Ford Super Duty (1999-2016) :: Check Engine Light Code For Injector Control Pressure Low
Traveling cross country & got a check engine light telling me "injector control pressure low". Replaced ICP sensor and injector pressure control regulator. Removed old one and installed the new one.
While looking for one of the nuts that attach the glow plug relay in the valley I found a small round part looks like maybe a valve seat. About 1/2" round with maybe a 1/4" four flute spline in the center. Has an o-ring on one end.
Is this something that followed the old ICPR out and fell off the end when It cleared the mounting hole? It looks like the ICPR would bear against this little thing.
