Why is my 2000 mustang 3.8l coding misfire #1 cyl?
This has been coding # cyl misfire for quite some time. You can feel the misfire at idle & cruising speed with no load on engine. Now the question: I have concentrated all my efforts on #1 Cyl. Finally decided to do a compression test on all cyls. Found #6 plug completely fouled with ash buildup. Obviously #6 is the misfire. Why does it keep coding #1? Also removed upper intake manifold & found oil & carbon in both intake & exhaust ports on lower intake manifold. (some cyls. Not all). What would be the cause of this? Please help, I'm biting myself in the back trying to find out the cause. Compression is good on 3 cyls, Marginal on 2 & one is below limits.
I recommend you take the Mustang to someone (preferably a local mechanic shop) to connect a real scanner on it, not a cheap one that the auto parts store use and sell. The mechanic will have to run a "Cylinder Contribution Test" which will show how every cylinder is working in real time. Numbers in the negatives will show that particular cylinder to have an issue. If you are have excessive oil and carbon build-up in the intake, you might have a head gasket or piston ring issue. Head gasket issues on Ford 3.8 motors are a little more common. Before sinking in too much time or money into that job, get a price on a low mileage salvaged engine. You might save a lot of trouble and money by going that route. Hope I could be of help.
- My 2000 Ford Ranger 6 Cyl 3.0 L has been overheating. Pretty sure its a radiator problem but odd symptoms? Truck exhaust will puff moderate amount of white smoke (every now n again) on cold startup but will subside after engine warming up.Truck "Was" overheating until i put more coolant in but realised cap was steaming along with coolant reservoir (reservoir was also bubbling). So i bought a new radiator cap. I got a safety cap and after installing I drove a little and engine temp goes to red really fast. What could it be? Thermostat? Water pump? Blown head gasket?
- Are ford ranger body parts for a 4 cyl and v6 interchangeable? I have a 2004 ford ranger 2.3. I went to a salvage yard to get a hood for my truck since mine was really bent. The guy had one hood left and he said it should work. I put it on my truck but it would not close. I slammed it down and still would not close. The shape looks like it belongs to my truck but it just wouldn't close. All sales are final so i couldn't return the hood. I put the old hood back on and that one closes properly
- On my 2000 ford mustang why does my air pump (smog pump) only blow air for 5 seconds after start up? Is that normal? I have p0411 secondary air injection system insufficient flow detected. I've checked the hose that comes out from the pump, it's blowing air but I believe it should blow air for much longer than 5 seconds on start up.
