2001 Toyota Tundra Misfire

The next day there is a 95 chance that the truck will start with a rough idle and a misfire.

2001 toyota tundra misfire. Engine misfiring ONLY when it rains - 2001 Toyota Tundra 47 V8 My 01 Tundra has developed a habit of misfiring when it sits overnight and it rains hard. Im having issues with my 01 tundra with 305000 miles on it. About a week later was headed up north with a few hundred pounds in the back.

P0301 is a common OBDII trouble code that appears in the Toyota Tundra. It ran fine for about 10 miles then misfiring again with check engine light flashing. It has a bad ignition misfir.

So its mostly a code for V8 engines. A few weeks ago I stepped on it to make a pass on the freeway and was surprised at the lack of power. The P0307 code means that the cylinder 7 is misfiring or is randomly misfiring.

Looking for some help. Vacuum leak If your Tundra has a vacuum leak it can be very difficult for it to get the right airfuel mixture. Heres where im lost i have put in new plugs swapped plugs swapped coils with other cylinders and it stays in 5.

I have a 2001 toyota tundra that has a random misfire the check engine light stays on but the truck will run fine for a day or two then start missing again i had an exaust leak an thought that was what was causing the miss so i put new manifold gaskets on the truck that did not fix the problem so i had the truck tuned up plugs fuel filter etc. Start by checking for intake leaks and if no leaks are found the next step is to replace the spark plugs on cylinder 7. Then they replaced another coil and it.

I took to the dealership and said it was the timing I changed the timing and the problem is still happening. The codes are showing random misfire and cylinder 1-8 misfire. Random Multiple Misfire Detected.
