I'm not very mechanically inclined but need a little advice. I was given a 93 SHO, automatic, good shape but running a little rough. What i mean by this is it seems to hesitate when driving. When i'm doing about 35 and start coasting, the car seems to start jumping. when i press the gas it goes away and accelerates. this happens even when i'm doing 65 on the freeway. seems to do it in low RPM's. Timing belt, throttle sensor, fuel injectors? i know a lot of work has been done on the car in the past year so it doesn't need a lot of work. any advice would be cool. thanx.

Baggio, Give us a little more nitty gritty....
is the car an ATX or MTX? How many miles? How was it maintained? etc.

Hesitation could be from crappy gas, or it could be something serious.

the car has 120,000 miles. i believe the car had the major work like the timing belt and injectors done around 75000 miles. as for mtx or atx, i'm not sure what that means. sorry, like i said, i'm not to keen on the mechanical stuff. i would like to start learning and put some time into this car. its a beaut.
i do know the car was sitting outside for two weeks before i got it. i just finished the tank of gas that was in it and put some premium in. we'll see. what could be the serious problem?

Baggio421-atx=automatic tranny (which you DID say yours was)
mtx=manual tranny

See how your car is after running the new gas through it. Even if the car had work done at 75k, you may have to do it over again, as you are at the 120k mark, and these cars need a certain amount of maintanence done EVERY 60k. I do not know if the 60k maintanence would solve your particular problem, but a poorly maintained car will cause problems. If you do a SEARCH, you will find all the info you will need (and probably a lot more than you want wink ) on the 60K maintanence. Good luck with your new SHO, and welcome to the club!

Has the CHECK ENGINE light illuminated at any time? If so, it will have stored an error codes that will likely point to the failing sensor. This problem could be from something as simple as the throttle position sensor (TPS). This sensor can be had for less than $20 from AutoZone and installed with a Phillips screwdriver. You can learn the simple method to read the EEC codes (search in the Forum for this commonly posted link to Dali Design or SHOtimes) or take it to AutoZone and have them check for free.

mtx-manual transmission, atx-automatic transmission. Forgive 91 SHOplus, he don't read too good sometimes.

As for the rough running, sounds like oil in the plug wells. The best advice I can give you for now is read, read, read, read. Do searches on topics such as 60K service.

As for your mechanical inclination, let me just say that you have a few options as a SHO owner.

Option 1: If you can read 3rd grade english, have a modicum of manual dexterity, a place to wrench on your SHO and the desire to learn, you can become an adequate SHO hack errrr...mechanic.

Option 2: Find a good SHO mechanic. There are good mechanics who are not good SHO mechanics, just as I think I am getting to be an almost adequate SHO mechanic, but, I would be lost under the hood of a Nissan. If you are fortunate to find such a mechanic and have a fair amount of coin, your SHO experience can be a good one, although the ATX scares me a bit. There is most likely, somebody here who can recommend a good mechanic in your next of the woods.

Option 3: Take it to any old Ford dealer, reach down, grab yer ankles and stand by for a good ole' fashioned **** reamin'.

I don't know if this has been mentioned, but it could be the Torque Converter going belly side up.

My car has VSS problems (I believe) and that causes the TC to not lock up properly and I can feel it jumping or surging a little.

Thanx for all the posts everyone. Just got back from the softball game, got our ***** kicked. As for Ohio, I'm from cleveland. I live in Columbus but work in both. As for the new SHO, its an automatic which I'm not thrilled about but hey, i paid nothing for the car. So, I just drove the car home and it sputters and hesitates when I accelerate, especially around third gear. I disabled the overdrive and it really didn't do much for the car. Still hesitating, especially in low RPM's. The old gas is gone. The body is in good shape and the interior is ok. Overall i'm happy to have the car and can't wait to get down and dirty. I'm excited about working on a car with some balls and one that has great style. I'm gonna take it to auto zone on friday or saturday and see what the diagnostic says. thanx again.

After reading your last post, I wouldn't be surprised if you don't get any memory codes. That would point to the secondary ignition system as the cause of the misfire. That narrows it down to the plugs and plug wires. If you find oil in the plug wells, that also implicates the spark plug well seals as accomplices to the misfiring condition. The plug well seals would need to be replaced to fully correct that problem, but you can clean out the wells to buy a fair amount of time until you are ready for for the gasket swap. Search on the parts list for the upper end 60K. You will save yourself and your SHO a great deal of trouble in the future if you stick with the proprietary Motorcraft AGSP32PP plugs (FordPartsNetwork.com, $3.99 ea.) and Motorcraft WR-4033 wires (which also fit the 3.2L and are $44 cheaper, FordPartsNetwork.com, $83.99).

thanx again. i thought from reading the previous paperwork on the car that the plugs and wires were new, but I may have been wrong. I'm going to check the condition tomorrow and see how they really are. thanx for the link. i'll let you all know how it goes. I'm just hoping it's not any worse than plugs and wires right now.

baggio,

I forgot to mention the #1 rule here, listen to the poster directly above you. He's got a 91' with about 13 million miles on it. And rumor has it, it will still run a low 15 quarter.....while pulling a 3000 lb boat.

Did you pull a plug boot yet? You may have had new wires, but, if the well seals were not replaced they can be full of oil again. It only takes a few seconds to check the front bank wells. It takes slightly longer to check the rears, usually about 2 days for a greenhorn!! thumbs_u

scott,

Seen quite a bit of you here the last few days. Didn't get laid off again did ya? :D

Heh! He's probably taking advantage of his new employer's high speed connection....

So I got some time to really look under the hood today. Man oh man, the wires look like they've been in there since the beginning, which means the plugs can't look to good. Also, there is a layer a 1/4 of an inch thick of oil and engine grime. I didn't have time to actually pull the plugs but I kind of got the idea. I'm ordering new plugs and wires from the website above along with new seals. We'll see if that does the trick. I read a lot of stuff last night and have a good idea of which direction i want to go in. This board is awesome and is really motivating me into starting a new hobby. Thanx again and I'll let you all know how things go.

Excellent. Be sure to remove as much of the oil and dirt as possible before you remove any plugs and look at them. That goo will go into the cylinders and there is grit in there that will make a mess on the cyl. walls.

sunny San Juan Bautista,
It sure is a great forum. I used to dread the idea of changing a tranverse timing belt and water pump. Now I can't wait till another 60,000 miles goes by so I can do the 60K all over again! :D I want to see how dirty things get compared to the first 13 years/148,000 miles. What a sick addiction! thumbs_u

Another thing is watch out on ebay for a good deal on the factory service manuals for your SHO (Helms). It might take some time to get a really good deal. I was in a hurry and paid quite a bit for my torn up set but they're good to have.
