1996 engine troubles!!!!

Well this just started happening A WEEK AGO. I have 155,675 miles on my truck. I just replaced the spark plugs back in june (150,750 miles). They were the bosch platims as shown here...


My wires havent been changed in about a year to a year in a half. When i am driving and i am at a low rpm saying going up a hill, and i hit the gas even harder my truck starts to Jolt. It jolts the whole truck big time!!! And it keeps jolting untill i let off the gas or VERY VERY SLOWLY hit the gas once again. What is causeing this! My check engine light just came on today. Bad plugs? bad wires? fuel filter? transmission?

get the code pulled.

This sounds similar to what happend to my friends lightning after he installed a new pully.

JLP told us it was the sparkplugs. (dont think he as replaced them yet).

sounds like a few things could be wrong......(i personally don't like the bosch plugs, they seemed to wear out fast to me)

1. your plugs are not the right temp range
2. the plugs are not gaped correctly
3. you have a clogged fuel filter
4. you NEED TO REPLACE PLUG WIRES WHEN YOU REPLACE PLUGS
5. your tranny is going
6. your rear end is binding up..

other than that i dont know what it could be....

You don't have to set the gaps on the plugs. thats the type they are.

Wheres a place i can go and get these things today???? I was going to get a fuel filter,plugs and wires once i get off.

The oil is not going to make a difference at all. I would replace the spark plugs with MOTORCRAFT plugs and then drive it. Aftermarket plugs arent all they are cracked up to be. I would also replace the spark plug wires. Maurice has a good checklist going on up there so get those plugs changed first and put some wires on it.

1. your plugs are not the right temp range
2. the plugs are not gaped correctly
3. you have a clogged fuel filter
4. you NEED TO REPLACE PLUG WIRES WHEN YOU REPLACE PLUGS

The last two in his list are unlikely with your circumstances described.

Buying factory plugs will fix that, the heat range of the plug is determined by the length and also the electrode. If they are not hot enough then the plugs could be loading up causing it to run rich and misfire.

When I replaced my last plugs out. (5000 miles ago) they had a lot of white carbon build up on them. would that be caused by them not heating up and burning/igniting efficiently?

If there was white carbon buildup then you are running lean.

Not enough fuel is getting into the engine aka, low fuel pressure, low fuel volume, too hot of plugs, restricted fuel filter or injectors. The list goes on.

go buy some Motorcraft plugs from a dealer.....while you are at it, get yourself some Motorcraft plug wires....i got plugs and wires about 3 months ago for $80 from a dealership.......that will mostlikely fix your problem.....just like Bill said, aftermarket plugs are not all that great.........it is worth the extra money for the stockers

yea just go to your local dealer's parts department and tell them you want plugs, wires, and a fuel filter for a 1996 Ford Ranger 4.0 STX 4x4. Take your vin # just incase they ask for it........they will give you the correct parts for it......

then go to your local Autozone or O'reilly and tell them you want Ford fuel filter removal tools(get the aluminium ones if they have them) and that you also need a spark plug gapper........while you are there, get some spark plug anti-sceze(sp?)

the plugs should be gapped when you buy them, but it is always safe to double check before you put them it....

save a few bucks and get autolite plugs... they are the ones who make motorcraft and are exactly the same but have a different name stamped on them... you can change the fuel filter without the tool but you just need to make sure that you done break the clips on the lines...the spark plug gapper is available in any parts house but make sure you get the disk shaped one and be sure to put a dab of anti-seize on the new plugs... it is also possible that when you changed your plugs last time you didnt tighten one or more of them enough and they are not firing correctly now... just a thought

was that the one in the back on the pass side by the a/c? that one is hard to get at in my 3.0 and it seems near impossible to get at with a 4.0 unless you go through the wheel well

this one is on the driver side nearest to the firewall. The body lift help out but its some metal hose/housing thats real stiff and won't budg. It was at such an angle that i shattered the glass housing on the plug.......??

Didn't have time to do anything yesterday and prob will not today. But i think i found something more out for sure. The truck only creats a kicking motion when it is under load going up hill. Yesterday going to Napa my truck ran like a damn charm......? When i start my truck up it idles fine and rev's up fine......???

Ok what i found yesterday is not too good. I pulled 4 outta the 6 spark plugs and 2 of them had a real thick black substance on it, like almost a paste. That was on the THREADS of the spak plug. As far as the leads go, they looked fine, alil bit of carbon build up but other than that looked ok to me. And now my truck hasn't been feeling any trouble the past day in a half, but the check engine light is still on!!!!????????????????? I know a seal is prob bad. are they expensive to replace?
