Ford F-150 - 1997-2003 :: Ignition Coil Stripped While Another Snapped - Intake Manifold?
I was replacing my spark plugs and one screw holding the ignition coil stripped while another snapped. I have change 3 plugs (the easy one) and could have more problems. I spent half a day trying to drill the screws out to no avail and also noticed the intake manifold is plastic. I was thinking of swapping it out. This would alleviate the broken screw problem and make pulling the plugs easier. It also looks like it's just 8 bolts. Would swapping a new intake manifold in add any performance gains? Is there a manifold others recommend?
View 9 RepliesJetta - Volkswagen :: 2011 - Ignition Coil Replaced, Car Misfire
My wife's 2011 Volkswagen Jetta (2.0 I believe) is misfiring again. We took it to the dealership about 6 months ago and they said that the ignition coil had gone bad. They replace the ignition coil and said that the plugs needed changing as well. I went to Auto Zone and got some decent plugs and changed them myself at home without much problem. It seemed to work with the problem (although it didn't seem to completely fix it) for a while, but it just recently went back to misfiring. The current symptom is that it seems to misfire when the car is warming up, but misfires less when the car is warm.
The dealership says that the plugs that we got were not recommended by the dealer (they recommended Bosch) and that they need to be replaced. I think this is BS and it is not going to fix the problem.
Lexus ES 2007-12 :: Ignition Coil Malfunction - Misfire In All 6 Cylinders?
Started up my car the other night and my engine light came on, trac light came on... VSC msg came on the dash, engine was rough idling. I drove it home after checking my fluids... i took the OBD scanner to see whats going on, hoping i just need a battery change. Codes popped up P0354, P0300-0306. basically ignition coil malfunction, and my cylinders were misfiring.
I am at 62k miles and warranty crapped out at 50k. the problem was obviously electric, since all 6 were misfiring, otherwise it would only be a few. I haven't had any engine work, I just recently did a proper oil change at home(royal purple 5W30), which I've done since I've had the car in 07.. I took the car to the dealership for the CPU reprogramming for the recall in April.
About to take the car back to get it checked up on and fixed.. I am lowered on coilovers and 20" rims, which gives it a rough ride, but i dont think it would cause this problem. i dont track/race the car and i drive it relatively civilized. Lowered since 30k miles and 20"rims since 50k miles.
What could've gone wrong? timing off etc... i pulled my engine cover to check the connection points for the coils, all seems fine, no corrosion on the grounding points. i was only able to check the front 3 coils, the other 3 were hidden in the back and i wasnt able to look at them. i assume they should be fine as well..
Chrysler - Lhs :: 1997 - Replaced Ignition Coil / Crankshaft Sensor But Car Won't Start?
Drove 97 LHS home from work back at the end of June on a 100 plus day, it seemed fine, no indication of any problem. Got in it the next morning to go to work and it would not start. Cranks fine, hear fuel pump. So a few days pass before my husband can look at it. He did get codes. He replaced the ignition coil, put on a new fuel filter, and replaced a couple of modules. It would still not start. We towed it to a service station that we have used for years.
They replaced the camshaft sensor (and fixed the AC). I drove it for 8 days, no problems. Then on the morning of the 9th day, it would not start!! Exact same symptoms. So towed it again back to the service station. Then they said it was the PCM (control module). Husband went to junk yard to get one (much cheaper). Service shop put it in and then said that was not the problem and replaced the crankshaft sensor instead. Say it was ready to pick up. I went and paid again! Got key and came back later with husband to pick it up. IT would not start!!!
Civic - Honda :: 2003 - Bad Ignition Coil
Found out today that my third ignition coil is bad, it's a Honda civic 03' my question is, do I have to buy a new ignition coil. I had a clerk tell me I could switch the coils and it would run fine? Is this right? could I just switch the ignition coil with another ignition coil? This doesn't sound right. Well If I do buy new one which would be the third ignition coil? is it counted from left to right or right to left? Are there any telltale signs of a bad ignition coil on sight?

View 2 RepliesPassat (B5) :: 2003 Misfiring - Ignition Coil Faulty?
I have a 2003 passat 1.8 and I just started having a misfiring problem. I googled it and ran across a 2003 press release that VW had recalled them. I am going to call tomorrow, but I did a little testing myself. Probably not the best thing to do, but this is what I did. I had my wife start the car and I pulled off the coils until I hit the one that didn't make the car shake any more than it already was. It is the second one from the front. I pulled the spark plug out. It is the original, but didn't look too bad.
My question is: How do you test the ignition coil to see if it is faulty or if it could be the distributor? The coil that attaches to the plug looks a little burnt around the rim where it connects to the plug. Its not an expensive part, but I don't want to go buying another one just to find out it is the main distributor or something else...
Mazda - Mazda6 :: 2003 - Chronic Ignition Coil Cause?
Can a problem elsewhere in the system cause ignition coils to go bad? I have an '03 Mazda 6s, 147k miles, owned it since new (Dec '02). 3 1/2 ~ 4 years ago, over a period of 6 months I had to replace 4 of the 6 coils. A month ago, one of the replaced coils went bad so I had all three rear bank coils replaced (cheaper to do all three at once rather than one at at a time since half the engine needs to be disassembled to get at them). This week, I started to get the initial symptom of a coil going bad on me: Occasional stuttering in the engine.
This issue always starts when it's wet outside. The first few times it started when going through a car wash, this last time was right after Super Storm Sandy dumped a lot of rain (I am not in one of the flooded areas, NH just got a lot of rain).
Ford F-150 - 1997-2003 :: 1999 - Persistent Misfire In Cylinder 5
I have a 1999 F-150 4.2L with a misfire in #5 cylinder. I have replaced plugs, plug wires and coil pack, checked compression (147 psi) and ran 4 cans of seafoam thru it and still getting misfires on acceleration. It'a a 5 speed and it sounds rough and runs a lil rough as I go thru the first 3 gears, then it runs good as I get up to speed and cruises fine at 80mph. I'm thinking a bad fuel injector???

I'm working on my 99 f-150. I replaced all my spark plugs and coils after I got a misfire on cylinder 3 reading on the scanner. The truck was running ok but two weeks later it started to ride rough again I checked the scanner and got the same reading for a misfire on cylinder 3. Why its giving me the same misfire again? Could my injector cause that misfire? What about the egr valve?
View 8 RepliesFord F-150 - 1997-2003 :: 1999 - Random Misfire While Driving On The Bad Alternator
I have a 99 F150 4x4 with 5.4 Triton, 99xxx miles. I was towing my boat when the regulator in my alternator went bad. I drove the truck with the voltage being sporadic for about 10 miles until I could get to a parts store. While driving on the bad alternator, I started noticing a misfire. I replaced the alternator, battery and DPFE. I still have the misfire....but here is the kicker. The misfire only happens when the truck reaches operating temperature. Which, in my limited knowledge, eliminates a fouled plug, COP, bad injector and a vacuum leak. I've got no check engine light so I can't pull a code. The only thing I can think of is to clean the EGR?

My grand am began shaking (shuddering) consistently yesterday morning and I ran a diagnostic reading on the car. It told me that there was a misfire. I replaced the spark plugs and still no change. This car has been a nightmare to do maintenance work on since everything is either within a case or impossible to access on a regular car jack - so what could be causing this reaction in the car? Is it definitely the ignition coil? I would just hate to attempt to replace that (not to mention the fact that it's $100+ for the part) if I didn't survey other options. 2003 Pontiac Grand Am 2.2....
View 1 RepliesFord F-150 - 1997-2003 :: 1999 XLT - Cylinder 4 Misfire / Shaking When Accelerate Or Idle
Ford F150 1999 5.4 XLT... I've had this truck since may 2013 from the 2nd owner who only drove it
occasionally to make sure it ran. For the last 5 weeks there have been two occasions where my service engine light appeared...once on 12/28/15 and again today. Both read cylinder 4 misfire. Upon searching this piece which I'm assuming is the boot that covers or houses the spark plug is very unsecure and causes a shaking feeling as I accelerate or idle. Being so far back I can't reach it with extensions on a ratchet and barely fit my hand back there. Having to consider taking it into a shop for further analysis and repair but I'm trying to save as much money as possible as I am in between jobs since mid January. I have a picture attached...
Ford F-150 - 1997-2003 :: 1999 4X4 - Intermittent Misfire / Runs Rough For About A Minute
I have a 99 F150 Lariat 4x4 with a 5.4, 150,000 mile on it. About 2 weeks ago I blew spark plug out on #2, and a friend who said he has heli-coiled a bunch of these tried to do mine and ruined the head. Anyway, I called a local engine shop and got another PI head, only I used my cam in it. Torqued it as per the book, etc... Mind you that the engine ran perfect before all this.
Got it back together with all new plugs, new exhaust manifold, and 2 new COP's. When I start it-it runs rough for about a min, then straightens back out to run perfect again, and after a few seconds you can hear a solenoid click, then it goes back to missing again. This goes on and on... I went through all the vacuum lines and checked them, checked the egr valve, put on a new IAC, new PVC, cleaned the MAF, and checked everything else with a DVM.
I took it out and drove it.... Runs good for a minute, then it goes back to missing, then back to smooth again. This just keeps going on and on. I noticed when I hear that click, it sounds like a mad rush of air being sucked in, but I cannot locate it. I ordered a new set of COP's to try next. I can understand if it just plain missed all the time, but this it intermittent. Also, the only code I can get is a too lean on bank 1, so I replaced the 90's and the pvc valve. Now no codes but still in and out of missing. It ran perfect before the new head.

View 6 RepliesFord F-150 - 1997-2003 :: 1999 - Misfire / Running Rough - Code P0305 And P0174
Here is my situation : I have a F150 1999 4x4 ext cab with 326 000 km. A little while ago I got a P0401 code so I decide to clean the TB first and at the same time change plugs and wires since they were overdue. The same code came back and a misfire. Ordered EGR valve, DPFE sensor and selenoid. Realize that I had ordered crappy plugs by mistake. I change all plugs. Had to wait for the EGR valve and others to arrive. I drove the truck for a while since I did not have the time to change the valve and others, during that time the misfire did not come back. Yesterday I change the EGR and others. Today I get a truck that runs really rough and got new codes , P0305 and P0174. I'm really confused now on what should be my next step, should I change the coils, can a P0305 cause a P0174. Should I change vacuum hose going to the EGR , selenoid and DPFE.
