misfire

Hey all, just recently found this forum as I recently purchased a 1999 Town Car Signature just about a month ago. So far the car has been amazing and I adore it, even with 201k miles it runs like a dream. Well, until recently. I've noticed sometimes it bogs down when stopped in drive and the...

I've currently dealing with some weird issues with my 2003. The car will run perfect then all of a sudden, it stops running on 3 cylinders. I get the EXACT same codes everytime. P0351, P0353, and P0357. I know these are connections issues and not misfires. The problem doesnt seem to happen in...

I’m having some crazy issues with this money pit so I’m seeking assistance from you knowledgeable folks. I want to make reading this post as easy as possible so I will format it as follows. A: backstory B: History of issues C: what I’ve done D: current issues. A: Backstory I bought this car...

Hi All, I am having issues with my car. I keep getting this misfire code. I have replaced the sparkplugs, coil, fuel filter, injector, air filter, evap, evap solenoid, air filter, oxygen sensors, pcv, and there appears to be no broken vacuum lines and code still comes up. Car turns on and when...

For months I’ve had random misfire problems and engine too lean codes. I changed coils and plugs and it was better for a day before engine light came back on. Rough idle, low power, mpg loss, light will flash when trying to accelerate at higher speeds. Changed PCV valve and hoses after mechanic...

1995 Cartier Town Car with 193,000 miles. Had been running great with slight hesitation if "mashing the gas". One day, oil light started coming on when braking to stop, checked, looked at correct level to me. Maybe a week of driving more and then morning I was going to get oil change, very...

Hello, I have 2004 Lincoln LS8. I love the car but having some terrible issues. I have about 80,000 on the car and have always maintained it perfectly. First I had some misfires. I changed the plugs and swapped out some of the coil packs with new ones I bought. No help so, I then put a crank...

So here is where I'm at, I had a master tech look at the car for about a month. The 2005 navigator with a 5.4 misses at idle, pops lean codes on one bank and particularly two cylinders i believe bank 2 and cyl 3 and 5. the other time i can feel the miss is doing about 50mph when i just let into...

OK I bought this car yesterday. I noticed at around 80 km/h it starts to shudder. I attributed it to the torque converter locking on 1500 rpm. When I got home the check engine light came on and it gave me a "random misfire" code on cyl 1. I cleared the code and drove it around more (to see if...

2003 lincoln town car executive. Started with the seperation of thermostat housing and crossover. The coolant leaked into driver side coil/ plug wells and caused misfire. Parked the car for a few months to save up for new intake manifold (Dorman). replaced all spark plugs with motorcraft and put...
