It is the V8 with auto box and when in 4th gear it seems to either misfire or get to much fuel, but have been told it might be the gear box?

A misfire feels like the engine is studdering, is that what it does? If it is a misfire you will also have a blinking check engine light when it occurs.

SOURCE: my 1993 discovery v8 auto wont change into 4th gear

It sounds like you need to have your d-tent adjusted which is your kick down cable. I would take it by a local transmission shop and have them take a look. This would be the simplest, most accurate answer as to what is going on. If they say your transmission is shot, ask them what they believe the problem to be. Automatic transmissions are complicated. Hope this helps.

SOURCE: Engine misfire...

First off what you want to do is see if the coil is keeping fire to the cylinders. If so is the fire blue or redish/orange. If it is blue then its not a firing issue. If it is red then you probally need a new coil. Now if you chose option A then check the spark plugs and make sure they aren't fouled out. The way to determin this is that they will be black and smell like gas really bad.If not then check the spark plug wires and make sure they are not ripped, broken, cracked, or show any signs of failure, If not then make sure it is getting plenty of gas. If not then it is either the fuel pump or the fuel filter. If it is a fuel injected engine then make sure the injectors are all working properly. To do this you will probally have to bring it into a shop and have them check. If it is a carberated engine then manually chock the carberatur by holding the top flutter valve closed for a second or two. If the flutter valve gets covered in gas real quickly (in less than 2 seconds) then it should not be a problem with the carburator. If you are still haveing problems with it after checking all of this then give me a shout back and i will see what i can do.

97 chevy 1500 sputters at idle in gear can feel it a little while driving no cat. past 2 years run bank1 lean code plugs clean HELP

If the engine is misfiring the check engine light would be on and blinking and the engine control module (PCM) would store a fault code or codes for the cylinders that are misfiring. A lean code will not cause a misfire unless the engine has a vacuum leak most often at the intake manifold gaskets. A misfire code looks like this:

P0300-P0306 for 6 cylinder and P0300-P0308 for a V8.
P0300 indicated a random engine misfire, this can be caused by all kinds of issues.

Code p0734

Why didn't you google your codes & read up?

The 302 is a cylinder misfire
The 431 is a worn out or ruined exhaust converter from the misfires
The 734 is a 4th gear incorrect ratio-mostly a failing trans

I would suggest we go no farther & you part with it while you can

If you had no trans issues-- I would say you have a neglected but
fixable car

With the cost of trans repair & a 2003 wouldn't spend any money
on it

Lincoln ls shakes

Is you "check engine" light on ? If it is you can take it to most of your local auto parts store and have them pull diagnostic trouble codes (DTC's) for free which may help narrow down the cause of it shaking. Not sure exactly what you are saying. Do you seem to have hesitation when pressing down on the gas to move ? As you are driving is there or does there seem to be a "stutter" once in a while like a chug. I say this because Ford products (your engine V6 or V8) have a separate coil for each spark plug that basically sits on top of the engine. Since your vehicle is a little older the coils go out on them because of the heat which causes a misfire which would cause shaking like you described. A misfire code would be in the P0300's area on the list of DTC's. I may be way off base but this is a common thing that happens with this coil on plug system. Hope this information helps....

98 Sportage changed new plugs, wires, and boot and (fuse?) for coil packs. But now misfiring on 4th cylinder. Prior to tune was only getting poor fuel economy no misfires at all. What would i fix next?

if you started out with no misfire at all and then got a misfire after the tune up that does seem strange, my best guess would be that the plugs are not gapped correctly or the spark plug wire is, not completely snapped on, or the wire on the 4th cylinder was damaged when it was removed, i would start out making sure all the wires are on, you will either hear of feel a small snap when the wire is seated on the plug good, also make sure the wire is connected to the coil good
