Question about 2001 Ford Escape

2 Answers

2001 Ford Escape has a random misfire when cold...had recent spark plugs changed from a garage..just replaced leaking intake gasket because it was not changed when it was removed to change rear plugs. Also, rpms take a long time to return to idle when reved...is this normal? if iac is disconnected the rpms are quick to return to idle.

Wondering if one or more CATS are pluged ??


Is there any oil in your coolant or coolant in your oil? (Oil would look like chocolate milk and coolant oil would be obvious. Sounds like a possible head gasket leak due to preignition or misfiring of the cylinders. Also double check the plug wires to make sure they are all on the correct cylinders. If two of the plug wires are reversed, it could cause this issue. The car should still run with out any cats but it will throw a check engine light. I'd bet it's either crossed wires, head gasket, and possibly a bad thermostat.

What is the reason piston #4 is misfiring


Hi
The misfire could be being caused by a number of things, such as:
1. Worn/dirty spark plug - Clean/replace spark plug/s
2. Spark plug lead breaking down - Replace spark plug lead
3. Or possibly the intake gasket. If the intake gasket is leaking it causes a vacuum leak. with this vacuum leak at idle it will cause a misfire. - To check this, take a can of carb cleaner (or WD-40 may also work) and when the car is running, spray it along the intake by cylinder number If you see/hear the engine change then you have a leaking intake gasket.
Trust this helps

2001 ford escape rough idle


since these are coil over plug, wires are out of the question, but not the coils. Although on this model, it would hard to test out since u need to remove the intake to get to the coils. But if it\'s been running like that a while, you should probably have a check engine with a code stating a cylinder misfire. If so, check if it\'s a specific cylinder, or a random cylinder misfire. If it\'s specific, you can swap 2 coils for one another and see if the misfire changes cylinder. if so, then you will know which coil is shot. If it\'s specific but changing the coils for one another doesnt change the cylinder misfiring, then the injectors are probably problematic. You can test that theory in the same way you did with the coils, but be sure to empty the pressure in the injection line before taking an injector out, or else you\'ll have a huge mess on your hands. If it\'s random misfire, then that will be a bit harder to pinpoint. You\'ll need to check for air leaks due to damaged/worn gaskets or vacuum hoses, check for fuel leaks from the injectors due to bad o-rings. If all else fails, just write back with what you\'ve tested and i\'ll try to help you find the problem.

2001 ford escape 3.0 engine no power in cylinders 4,5,and 6


wonder if it brings a check engine light on? check your coil packs spark plugs/wires - could be a bad injector - could be a vacuum leak - could be an intake leak causing anifreeze to be introduced into the combustion chamber - same with the head gasket could be blown causing the same effect as an intake gasket most of the time if you check your spark plug they will tell you everything like oil on them would be black and oily if its been introduced to water/anifreeze could show signs

2002 ford escape misfiring changed all plugs gaskets boots


I would have it scanned and check what cylinders are still misfiring. I would change the ignition coil for that cylinder and see if that fixes the
problem. If the misfire is still there...the PCM will likely need replacement.

Heavy idle, random misfire code 04 trailblazer


I would start with the inlet manifold gasket, these are know to break down causing vacuum leaks which can cause this issue, also check around engine for other vacuum leaks

My 2003 Escape has a history P0351 and P0301. This vehicle is also surging at times, at idle or around 40mph. I've changed the affected coil and intake gaskets. Spark Plugs recently replaced. Any...


I had the same problem and replaced the spark plugs, and also the tubes that run from the coils to the spark plugs. there is a spring inside the tubes that was brooken and that fixed the problem.

Random misfire,1.6L ,ecm, changed coilpack, new plug wires,


Try low end plugs like

Autolite 3923
Autolite Ignition Spark Plug: Copper Core; Price Is Per Spark Plug Spark Plug - Resistor Type: Oe Style; Gap .044
NGK Spark Plug: Plug No. BKR6E-11 V-Power Spark Plug: Gap @ .044
Adjust the gap to 0.44

Top off coolant tank and start monitor or the next few days.
If you are losing coolant then it can be the 1st sign of blowing head gasket.
Do a pressure test if the temp is getting higher and losing coolant.

Old worn out O2 sensor will not provide the right data to the ECU.

I'm leaving the tough on to the later here.

Vacuum leak on air intake tube / lines / and valve cover are VERY tough

If it's over 4 years old then change it. It will help you save on gas mileage.
Take your time and check one spot at a time.

Random misfire is not a easy fix.
