I have had the same problem on several chevrolets in the past. The problem was either a broke rocker on the valve trane or the most common is a flat cam lobe. A flat cam lobe will not let the valve open fully or not at all.

Have a 2006 jeep liberty 3.7 that feels like it's misfiring or transmission converter is going in or out of lockup. There are no codes being set. This problem happens randomly at all speeds. Any ideas?

you drove with scan tool running did you to see if you get
any P03xx codes on the FLY? yes/no
some can pop in and out fast.!
missing that fact ,misses the boat.
if engine is not misfiring then its a/t
the TCC lock up only happens under very specail set of rules
light loads. if you learn that (off FSM chart) you can drive
car such that TCC is defeated and if it misfires now ,its the engine
easy peasy

do a tune up in last 9 years>? full engine tune up.
and check trans levels too.

if random , you need to use the scan too better.
driving, you get wife to drive and you scan, see?
the PCM will report many things, but you need to drive it.
my cheap scan tool can log for hours. and can come one
and see all live streaming data (PID's) and all DTCs during that time
sitting at my desk. (omg, the crank sensor burped, 6 times)

1999 v6 firebird misfires on #6 cyl when under load, plug was fuel fouled last time I had it replaced, but keeps missing only when under load. no other problems.

if you've changed the spark plug and no difference, then it's time to swap the coil with another cyl. coil and see if the miss goes to the other cylinder, if it does'nt follow to other cylinder, then I would replace that injector !

I have a 1999 s- type Jaguar with v 6 engine. Recently it has begun to develop a shudder or miss especially when under load on an uphill climb. Upon inspection I noticed that the engine oil level was below...

no, and you were down a litre that wont matter, it sounds like a bad coil boot or coil thats arcing out on a load, i think this car has coils that go onto the plugs and the boots go bad, you can replace the boot on some cars without replacing the whole coil, you may want to tune up the car if its been a while and has over 70,000 miles,also if the engine was misfiring then the computer would pick up the misfire and store a code, this code which can be pulled with a scan tool, or most auto part stores will scan the computer and give you the code the code will tell you which cylinder is misfiring this way if it still misfires after the tuneup then you would need to replace the coil for that cylinder, heres a few diagrams showing the coil and theres one for every cylinder and then the boot which is sold speratly, hope this is helpful,johnjohn2_49.jpgjohnjohn2_50.jpg

I have 1997 Silverado 5.7 miss on #5 when under load take your foot off wait put your foot backin and it will run fine did all the wires plugs cap rotar same miss more so on uphill what do think is wrong?

If you have isolated to one cylinder, you need to look at the compression on that cylinder, should be at lease 110psi. Also check the valve springs, a broken spring will allow engine to run smooth unloaded and miss under load. Remove valve cover and push down on valves, if they move at all the spring is bad. You can also do a cylinder leakdown test and it will tell you if you have a valve or rings going bad.

My 2002 Ford Ranger Edge V-6 is misfiring after it warms up when trying to accelerate or under a load, going uphill. The vehicle jerks around 2500 rpm and above 45 mph. It doesn?t **** as bad at higher...

havent a clue here ,one cylinder now another missing ,only one thing comes to mind here and thats the coil pack ,check the voltage across the battery with engine running at 1500rpm and if its higher than 15.5 volts of their abouts then the alternator regulator is playing up and this would cause problems with the coil pack or the ECU ,also the radio could blow and lots of bulbs.Other that this i would need to get my greasy hands on it and give the magic hammer treatment

Has a 6.0 L with bad misfire under a load and is

Hi Brad,
I ran into the same problem your going thru,
swapped cylinder plug and wire ,and the scan kep telling me it was still seeing the problem on the same cylinder,
smoked it too,nothing made sense!
Until i took the whole fuel rail off carefully not to let the fuel run out all over the engine,Had a white rag folded up and handy,tilted the rail assembly and left the fuel run on the cloth,OMG! the rust that came out of there,
I pulled every injector out of the rail,cleaned the inside of the rail with air pressure and carb cleaner.
Its when I was checking the injectors that I found the culprit,the rust pieces had made it thru the injector but were trapped in the screen of the injector!
I hope this cures your.
