Ford F-150 - 1997-2003 :: 2003 - Running Sluggish Even Replaced Plugs / Cops And Cleaned MAF Sensor?
I've tried everything I can think of and it still runs sluggish.
1. Had dealer change plugs
2. Changed Cop's
3. Cleaned MAF sensor
The 5.4L has slight miss and doesn't respond well at all when trying to pass or going uphills.
Ford F-150 - 1997-2003 :: Replaced Plugs / Coils Now Truck Won't Start
Yesterday I decided to tune up my 2003 5.4 for the 1st time at 82k miles. I replaced all 8 coils with MSD coils & motorcraft plugs. After doing so I went to turn over the ignition & got 1 single click, motor wouldn't even turn over. Battery is 3 months. Truck ran just fine prior to tune up other than the slight misfire I was starting to get.
When I was working on the passenger side I did disconnect the big bracket that had the multiple wire harness on the fire wall underneath the starter solenoid to gain access to the rear plug/coil. Where to start troubleshooting? I checked the fuses under the hood & dash but nothing looked blown.
On a side note I remember when I was putting everything away I tried to lock the truck with the Ford factory transmitter & it wouldn't lock?! I had to open the door & press the power lock button to lock the doors.

I recently purchased a 1997 F150 4.2 Liter. On the way home it started missing. Within the next few days it died on the side of the road. After towing home I found no spark. A few days later I t started but only for a few minuites and died. No spark, coil pack is new so I replaced the CKP and it started up. Drove it about 1/2 Mile and died again, No spark again. Not getting power to coil pack when I am turning it over. So in short, new coil pack and CKP sensor and no spark. If it sits for a few days it may start or it may not. But if it does it only runs for a short period and then no spark again.

I just changed my spark plugs the other day and since then my engine is hard idling and skips and jumps while I'm driving it. I'm being told I either need to change the spark plug wires or the coil packs. So my question is which do I need to change? And is there anyway to test which one I need to replace?

View 14 RepliesCamry :: 2002 SE V6 - Replaced Spark Plugs / Check Engine Light Came On
I recently replaced the spark plugs on my 2002 Camry SE V6 (Gen 5). Let me just say that it was INCREDIBLY DIFFICULT to reach the rear 3 plugs as they sit underneath the intake manifold, way to the rear of the engine compartment. To reach those, I had to unplug some wires reaching on top of the engine, then loosen the intake manifold.
Along the way I broke a tiny air valve that sits underneath intake manifold, and replaced it right away, before starting the car.
When everything was put back together, the car started wonderfully, only to notice the engine light come on. I had the codes checked at the dealer and they indicated a malfunctioning Catalytic Converter and A/F Sensor and some other emissions stuff. Later that day, the VCS/TRAC OFF light came on as well. The service guy at the dealer said those typically come on together with the Check Engine light, which sounds like something he pulled out of somewhere!
The car drives well, no hesitation, no weird behavior, but has no traction control, naturally. While loosening the manifold I had to use a little force to flex it out of place. My guess is that it I may have yanked something out place: may be a wire issue, or a sensor.
Prius (2004-09) :: Hybrid Warning Light Came On When Replaced Spark Plugs
My husband just replaced the spark plugs in my 2005 prius with 174,000 miles (also replaced the right headlamp bulb). When I started the car, the PROBLEM check engine light Hybrid Warning Light came on.
Owner's manual says take it to the Toyota dealer. The dealer is 50 miles away. Is it safe to drive it the 50 miles? It drove okay up and down my driveway.
Honda - Odyssey :: 2005 - Replaced Spark Plugs / Gas Pump / Gas Line Still Getting 14 Mpg?
I have a very well maintained 2005 honda odyssey with 150,000 miles on it. It typically gets 22 m.p.g. It started using an unusual amount of gas - was getting 12 m.p.g. Took it to the mechanic and turned out the gas pump was cracked. We replaced the gas pump and the gas line, and it was getting 14 m.p.g. Took it to another mechanic, and he said that the spark plugs were the problem as they were not official Honda spark plugs (we replaced them at around 110,000 miles). So we installed the official Honda spark plugs, but still no good. I have visited several mechanics and no one seems to know.

View 10 RepliesFord F-150 - 1997-2003 :: 4.2L - Suddenly Started Missing Under Load
My 4.2 liter F150 suddenly started missing under load. A little background: It is a late 2003 and has 75k miles. It has been in my family since new, and I have had it for the last 4 years. This truck is as stock as they come, and has been well maintained.
On my way to work yesterday, it began missing. Not bad at first, but got worse. It misses while under load and under acceleration. The "check engine light" never came on. I have not put fuel in in several days, and it ran fine until now, so I doubt it is bad fuel. I started the engine after dark and looked for arcing. None visible, and I even sprayed the wires with a mist of water. I pulled the plugs and they all look normal. The gaps were all way too large, so I regapped the plugs to .054". I pulled the coil pack and it checks within range with my VOM. Can the coil pack be the problem even though it checks out on the bench? Can the large plug gaps have contributed to a coil pack failure?
Where to start. I HATE just throwing parts at this thing, and I don't like wasting money... If I let one of the auto parts stores run a scan, will it show a code even though I have no check engine light? I used to think of myself as a pretty good diagnostician, but then again, when I used to spend a lot of time under the hood, those cars had points, condensers and carburetors...
Ford F-150 - 1997-2003 :: Truck Randomly Started Missing - Misfire On Both Cylinder 1 And 8
I've got a 97 f150 4.6 that has randomly started missing over the last month. It has started to get more frequent and codes are showing a misfire on both cylinder 1 and 8. Both of these cylinders run off the same coil pack. I'm thinking its the coil? The plugs and wires, motocraft, have about 3k on them and the truck runs great otherwise. I just don't know how common a coil would cause this or if they would act intermittent like this.
View 5 RepliesFord F-150 - 1997-2003 :: 2001 - Started Shaking At About 30 Miles?
I have a 2001 f150 7700 edition. The truck has 118,000 miles and i've owned it for the past three years, the trucks great and really reliable. I drive the truck every day 50 miles to my college and about two weeks ago my truck started shaking . I had just got off the highway and made it to a stop sign. I then took off and when I hit about 30 miles an hour the truck started shaking but when I hit 40 it stopped.
I said whatever and ignored it. now it does it pretty much anytime I go past 30 miles in hour. My tranny shifts good. I checked the fluid and it was normal. smelt it and it didn't smell burnt or anything still pretty red. Some days its worse then others. Also, no engine lights, tranny lights, no obvious lose parts, tires are good. It only shakes when I give it gas. I let off the gas at 80mph and it doesn't shake at all. Which is why I'm confused.
Ford F-150 - 1997-2003 :: 2000 Truck Started Missing And Code P0302 Came Up Along With P0171
I have a 2000 f150 with 5.4 Triton with 165k miles. I did invest in a code reader. It started missing and code P0302 came up along with P0171. Put new coil on #2 and truck ran fine for a few days. Then it started to run rough again. Shaking, Idle rough, no power and CEL came on again. This time code P0171. I changed out fuel filter to no avail. My next step was to start looking for vacuum leaks. As I'm searching, All I am finding is trucks with this problem also get P0174 code. My question is since I am only getting lean on one bank does that pretty much eliminate things like MAF or the famous elbow vacuum leak and make something that only affects one bank like an O2 sensor on CAT more likely?

I have a 2000 f150 4x2 5.4 168k... Check engine came on,started shaking, weather was really cold. RPM would be a little high then low then back up. Especially when I turned on heater. Felt like truck would die but never does nor does it have issue starting.
So far, I have replaced two oxygen sensors inside engine,all coils, spark plugs, fuel filter, had injectors cleaned, intake cleaned. Truck runs better but, light came on a day later again. I can feel the tiniest of shaking going on and, cold mornings still make RPMS a little unstable. I was driving truck on highway at about 60 mph when a slight tug was felt and Truck check engine came on. I feel truck heavy, once it warms up completely, a little lighter.
Codes came up at auto zone as P1151
But I'm running out of options and frankly, money to fix this truck.
Checked the MAF and looked okay.
I'm with minimal skills.
Ford Ranger / B-Series :: 1989 2.3L - Started Missing Even Replaced Fuel Filter?
The other day I was driving down the road on a long, flat section and all of a sudden my truck started missing out of the blue. Ever since it started missing it hasn't stopped. The truck is an '89 Ranger, 2.3l, 5 spd. The plugs and wires were replaced last year along with the timing belt and fuel pump. It has been running great since then until now. I thought maybe it might be a clogged fuel filter so I replaced that but it didn't work. Also, it doesn't miss all the time. It doesn't miss when its idling or if you are going down the road while it is missing and slowly release the gas pedal it reaches a point while you are letting the pedal up where it will even out. It definitely seems like it is an "under load missing" scenario. Also, the Check Engine Light is not on. Where should I start looking?
