Hello everyone, running into a bit of an issue with my '03 Silverado 1500. I replaced my rear parking brake cables and my intermediate cable, but when I go to connect the two, there is too much tension on the front cable causing about 2 inches distance between the bracket and the intermediate...

Hello everyone, finally figured out the problem. The fuel injectors were faulty. Makes absolutely no sense because they showed no sign of fault on scans. Every strange. But thank you everyone for your input and pointing me in the right direction

I have the long term and short term trims, looks low negatives

Here are the individual cylinders. First photo is at idle. The next series of photos is immediately after ignition. The first photo I didn't add the rest of the cylinders because they all read 0 after each cycle. The misfires only go as high as 10 after ignition

I will definitely check that, just replaced the MAF on Friday. Guy who owned it before put a K&N cold air intake and the hose never has seemed to fit correctly. Even after installing rubber seals on each end. However this problem appeared after that.

Been a while, finally went out and bought a semi cheap diagnostic reader. I went into the individual cylinders and read the misfires. At idle, cylinder 1 didn't miss fire more than 3-4 times per cycle, cylinder 5 no more than 1-2 times per cycle. However, upon ignition, every cylinder began to...

One mechanic had said they already swapped and tested the coils, and I had installed new injectors and plugs/wires, all OEM. I don't notice a misfire, and the truck doesn't go into Limp mode. And the only code it is throwing is a P0300. Random cylinder misfire, so I believe it is something...

I will definitely look into that. I've been in and out of that engine bay dozens of times and haven't seen many signs of rodent activity. But at this point anything could be the reason.

hello everyone, it's been quite a bit since I've updated. Trucks been off the road since November and had to purchase another daily driver, and couldn't get much work done due to a particularly cold New England winter. Been driving the truck for about a week doing some tests. None of the...

Merry Christmas everyone, so a couple of updates. Sent the truck to another shop that specialized in Chevy trucks, they did a deep cleaning with seafoam to remove the carbon build up in the engine, seemed to have fixed the misfiring issue. As for the long crank, I still haven't solved it, I have...

Hello everyone, back with another update. Truck was at the mechanic for 9 days, they allegedly started it up everyday, never once had noticed the long crank issue. But within 2 days of having the truck back the issue reared its head again. I've noticed that, with the mornings here now being in...

Tried explaining that this is a new issue, and it's definitely not a coincidence that immediately after replacing the plugs the issue arose. The trucks in good shape, and both previous owners kept an entire record of receipts of on time oil changes and regular maintenance. These engines last far...

hello everyone, didn't want to leave this thread unanswered, so figured I'd give an update. Decided to bring the truck to the mechanic. He told me the misfire code is due to the engine being worn, and misfiring in all cylinders . I tend to disagree due to the fact that it just immediately...
