So i replaced my IAC(Idle Air Control) Valve and the idiling is much better! However my shaking/jerking has not stopped. I have found the problem which is the exhaust manifolds! I was wondering if when i replace them which i am probably going to get headers should i use metal gaskets?
View 14 Repliesreplacing exhaust manifolds on my 2008 f250 super duty got a broken stud on right front top tried to drill it out but there's no room somebody said to weld a nut to the broken stud but if I do this will the weld mess up the aluminum head.

View 14 RepliesCan't put it off any longer. Cold start I am getting the exhaust leak at the manifolds on an '01 V10. It's worse on the passenger side than on the driver side. So, I know the bolts/studs fatigue and snap off causing this. With my luck probably flush in the head. So who has done these and how bad was it? If I'm going to do this I am going to swap in a set of shorty headers instead of installing gaskets.
View 14 RepliesI have an 2003 Explorer 4.0 and I am looking at replacing my muffler. Only problem is I don't know who to go with. I am looking for a mellow tone with minimal interior noise. I have been looking at Flowmaster, Magnaflow & Dynomax although I can't make a decision. I have heard how the 4.0 Ranger sound's on Magnaflows website(sound's OK) aside from all the horrible sound clips floating around that don't have good quality to listen too. I was looking at Flowmaster 50 series Delta Flow and there SUV muffler(a tad thicker than Delta series) but want some feedback on who/what to go with. Also, right before the tailpipe ends, next to the spare tire underneath, there looks to be what looks like a resonator if I am correct on the tailpipe. Can this be removed and replaced with new piping? Will it hurt performance or make the exhaust sound different?
View 14 RepliesMy wife's 97 f150 4x4 had an exhaust leak on the passenger side. 7 out of the 8 bolts holding the manifold on are snapped off. 4 of them are snapped off 1/8" below the top of the hole on the cylinder head . I am I unable to get a drill in to drill these out. The other 3 I've tried welding a nut on these but they won't budge and I wring the nuts off. If I have to pull the head(something I don't want to do)can I just pull that 1 head or do I have to tear the intake and everything off?
View 1 RepliesI have been thinking about toying with my exhaust. I don't have a crazy amount of money. I got a 94 F250 with the 5.8 liter 351. Heres what I was thinking. Get rid of everything after the cat, and then run a single 3 inch pipe from the cat to a flowmaster 40 series, and then exit either right before the back tire or right after it.
View 7 RepliesI have a 2003 ford ranger 2.3 vin d 5 speed, this truck originally... Took it in for wires plugs front brakes fuel filter battery and added a small cold air intake. We discovered a valve cover leak and while repairing guy drops a screw into a valve and when finished he started it lodged the screw between the valve, shearing off a cam sprocket bolt. Throwing the timing. 2 valves on the exhaust side were bent and replaced. no damage to the head.
Timing was reset and the truck was running. 2 days later truck is running/had a hint of exhaust smell then started bogging dying and shaking, at which time we got an 02 bank2 lean code and fixed that. it cleared code and didn't fix it. From there we replaced coil, imrc intake bc of a crack, tried and check all vacuum, reset the timing. Timing would slip before but no longer than 10 minutes every time truck started.
Found the hole in the timing cover that holds the bolt to torque? to harmonic balancer was broke. replaced along with the diamond washers and cam sprocket bolts. timing finally held crank sensor was adjusted. truck came home for one day running good, we had removed the cold air intake and replaced the factory air intake. next day it was so slow outta first gear, you must baby the throttle, if you floor It, it sputters and kinda pops, truck stays slow all the way to about 10 mph and 2000rpm then it begins grabbing speed, 3000rpm is where this truck shifts the best, 2nd is better, third better than that.
As rpm increase the truck runs better, it idles steady at 1100-1200rpm at stops with an audible miss and then struggles again on takeoff. Here what im wondering, the truck has an abs sensor that just came on, but no codes showing now.tomorrow I wil run matko determinator 3.0 on it. and test the catalytic converter. first how do I check the timing belt to see if it stretched? do these trucks store the p.i.d.s. koer or kams that could cause one, all, or any of this and if so do I have to have it flashed from ford or can you manually do this without a drive cycle test.
An idler pulley on my 2002 F-150 seized and snapped the serpentine belt. The pulley is below and to the left of the belt tensioner. The pulley doesn't have a bolt but a hole that looks like an allen wrench would fit it. I couldn't find an allen wrench to fit it. Called AutoZone and they have a pulley removal tool in three sizes. What size wrench would fit the idler pulley? I want to make sure I get the correct size tool so as not to screw up the pulley when I start pulling on it.
View 2 RepliesI have an 03 F350 Lariat LE with a stock sun visor (eyebrow) that broke off while I was driving on the highway. I have purchased the replacement. It is a 3 part kit and my biggest question is, how does the mounting bracket attach to the top of the cab. The old one did not come off, just ripped the bolts through the metal.
Here is the link for the parts: 2003 Ford F350 Super Duty - 18637467 Exterior Sun Visor.

View 7 RepliesFriend of mine has a 99 Ford F150 with the 5.4L. He thinks the heater core has gone on it as it blows a mist through the top vents when he turns the heater on. He can also smell antifreeze. Up here in Canada, its, well quite cold, nuff said about that. He has had estimates of anywhre from $800-$1000 to change it whereas the cost of the core is below $100. Is there anywhere that he can get a diagram.... of how to change it, all he knows was that he was told to remove the entire dash to gat at it.. Is that true ?
View 14 RepliesJust got new tires Friday. Now I have a very noticeable shaking right at 35-40mph. Doesn't do this at any other speeds and test d up to 80mph. Took back to where I got the tires and told them and they rebalanced them and yet it still does it. Could it be a bad tire? What am I missing?

View 1 RepliesI planned on replacing the timing chains, tensioners, guides and oil pump when I replace the timing cover tomorrow, however, I overlooked was the specialty tools to lock the cams and crankshaft in position. I came up with a couple methods but wanted to know of some other way to replace the timing chains without the cam/crank tools?
Turning the crankshaft keyway to 12 o'clock instead of TDC : Positioning the crankshaft keyway at 12 o' clock will keep all pistons close to mid cylinder and essentially eliminate the risk of interference.
or
Neutralize the cams : Loosening the bolts on the cam bearing caps while still keeping them in place allows the cams to move without engaging the valves.
I've had this truck since 2011. Ran great when I got it. Ive had problems with the calipers and I've replaced both the fronts. I keep up on changing the oil regularly. The manifolds started rusting away a little over a year ago. Not happening... The shaking started recently after I pulled a trailer with 2.5 tons of shingles on 2 separate occasions.
That being said, I can feel a little shaking while idling. It was really only bad between 500 and 2000rpms. After 2000 it almost felt like a turbo and it would accelerate really fast and smooth until the gears switched. I figured i should change the oil. Now the shaking is more violent.
Its a 2000 f150 5.4 v8....
My AC compressor failed so I replaced it.
I put in 1 can of R134, and I don't see the compressor cycling.
How do I remove the connector to the accumulator so I can jump it and force the AC to run.
Well...I had the ECM replaced on my 2002 F150. She ran great for about 60 miles. I had trouble with the key right off at the dealer - it wouldn't start, so I flipped the key over, and it started. Drove about 35 miles, and had starting issues a couple of times, but minor, and over quickly. Came home, and did not drive it for a week. Got in this morning, and it WOULD NOT START. Turned over normal, but won't start. Now I am stuck 15 miles from the dealer who programmed it, and no way to get it there. Anything that I can do to get it started to make the trip?
