    Has it ever shutdown on you like if you were driving a stick shift car and you didn't put in the clutch? If so it could be in your transmission on a part called the torque converter clutch solenoid that has gone bad. Need more info to help you out though.

Sounds like a fuel injector that is failing when hot, this will definitely cause a misfire. I am assuming this is a late model car as you never said what year it is.

Here: while cold Ohm test all the fuel injectors they should all be about the same, about 14ohms -16 ohms
then drive it until it acts up then quickly while it's still hot do the injector test again and look to see if any injectors are signatively higher or lower in readings. Most often you will see the reading lower which means a bad injector, Change the bad one with a new Factory part and clean the rest by sending them out to a ultra sonic cleaning facility (most good parts stores with a machine shop can do this service for you) send them out that is.

Poor idle and no acceleration on a '91 GMC Sierra 1/2 ton p/u w/4.3l v6 manual trans


there is vital information missing here
to start with it is a v 6 so there will be 2--HO2S sensors one for each bank before the cat converter and 2 --O2ensors --one for each bank after the cat converter
there is a vast difference between HO2s and O2 sensors as each reports different information to the ECM
next slow acceleration can be accelerator position sensor or throttle position motor
every time you read the codes it cancels them so you have to run the vehicle for a few miles for codes to reappear
from the codes there can be up to 7 reasons for that code to appear so you don't pick on the first one as it could be another or a combination of others

My 2004 envoy xl is reading two trouble codes. trouble code u1000 and p0300. is there a common problem that would read both codes?


Battery light is for the alternator. Not the battery. You can have it checked at a parts store. On the vehicle. The 300 code is for random misfires, all cylinders. This could be from a bad alternator. If the alternator is not putting out enough volts, it will draw down the battery. When the voltages gets to low, misfires are the first to happen. After that things start shutting down. Eventually the vehicle will just die. The 1000 code is a relearn/drivability code. Don't worry about it.

Some of these vehicles had issues with water getting under the hood through the seal at the cowl panel and getting into the back spark plug tubes, once the engine warms up and the water evaporates the engine will run fine. There is a replacement seal thatyou can purchase to solve this problem. Hope this helps.

2004 Ford expedition check engine soon light is flashing and car shakes hard when stepping on the accelerator


Your car is misfiring. You should not drive the vehicle while it is misfiring. If you want to DIY it you can start with you ignition system. Make sure all spark plugs, plug wires, and ignition coils are secure and in good condition.

I think it might be a fuel delivery problem.I would check the fuel pressure and make sure its within the specs for that engine.Its sounds like it could be a weak fuel pump.When ever the engine does'nt get enough fuel to mix with the air then it causes a lean condition which will make it misfire.If it was an ignition problem it would misfire whether it was cold or hot.

Random misfire


Intake manifold gasket or cracked intake manifold will cause a variety of problems including rough idle and random misfire. You can try spraying a little carb cleaner at various points around the intake manifold while the engine is idling and see if the RPMs pick up at any point. This would indicate that it is drawing air in someplace where it shouldn't. The slow acceleration is probably because the computer has set itself all out of wack and is trying to compensate, that's why you get codes like O2 sensor when it really isn't bad, it's just raw gas getting to it.

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
