1990 Ford Mustang Sedan Engine Hesitating When accelerating Always

I have a 2.3 L, 4 cylinder 5 speed. When I am accelerating in 2nd and 3rd gear between 2000- 3000 RPM. It is hesitating like it is going to stall. When it hits about 3000RPM it kicks in and goes good. What would that be? Also how do I know if I need more clutch fluid and where do I find where to put it in? Can you send me a picture?

Hello, A hesitation like this can be as simple as a loose clamp on the air inlet tube that runs from the air filter housing to the throttle body.

Air that gets into the throttle body that has not passed through the air filter and the mass airflow sensor (MAF) is called "Un-metered" air. This causes the computer to call for an incorrect fuel amount.

That's one thought. Do you see a check engine light coming on while the engine runs?

How current is your car's last tune-up?

Clutch fluid has it's own master cylinder under the hood on the firewall and will be located next to the brake system master cylinder. If it does not have a transparent reservoir you'll need to remove the lid to see the fluid level. The clutch master cylinder will be the one closest to the left front fender, just as the clutch is located closest to the left side of the car.

Still need a picture?

Please advise,

Roger

No, A picture will not be nessary. Thankyou.

1989 Ford Mustang Sedan Electrical / Lighting Systems Malfunction Happens always 

turn signals will not work. Checked all fuses, checked and replaced the flasher unit. Replaced turn signal switch. The emergancy flashers will work. Brake lights, and back up lights work. headlights work, and the high beams will flash when pulling on lever. Is there something I am missing that might need to be checked!????

it could be the emergency flasher thats gone bad, if that one isnt working as it should, you wont get the turn-signal to work.i would try to borrow one or get one at the junkyard to check if its working.

Hello,

I've re-opened this question at the customer's request.

What type of pilot bearing do I need to use a 4cyl. 5speed trans with a 302 v-8. I know the 4cyl input shaft dia is .59 and the v-8 is .668, I need to know what will make this work. What is the bearing actually out of? Please help! Thank you!

You will have to have a pilot bushing made at a machine shop. There is not a specific pilot bearing for this purpose.

Also I would take it easy on that transmission. The 4 cylinder T-5's are weaker than the v-8's

I was told that a pilot bushing from a BMW or a Volvo will work. Have you heard anything about that?

No, I havent.

I found it. It is out of an 85 Volvo 735 diesel. Thanks for trying anyways.

Wow that is a wierd one. Sorry I couldnt help you.

1988 Ford Mustang Sedan Heating / Cooling System Malfunction Happens always 

The main problem, is a lack of heat. I've changed the heater core and had the thermostat replaced twice because it is hard to ensure that the proper one is chosen by your friendly neighborhood paid wrench( I eventually obtained one from a ford dealership , after much conjoling and a bit of bribery ). The official thermo. fits further up in the housing than the after-markets which , of course, allows less leakage past the thermo.
This seemed to help , to a small degree , but I still have insuffient heat output as compared to my other Mustang with the same engine model.
I was wondering , if you had any thoughts or suggestions on the matter.
Also , I would like to know what the small offshoot hose that leads back to the engine from the heater core hose ( just before the heater core ) does... and is it a possible contributor to my problem .
My heat gauge only goes to approx. 140 F.( I'm a Canadian but still remember the Imperial system ).
any help would be greatly appreciated.

IT IS POSSIBLE THAT YOUR COOLANT IS NOT REACHING THE PROPER TEMP OR A FAULTY TEMP GAUGE
THE HEATER CORE COULD BE BLOCKED INTERNALLY WHICH COULD BE SOLVED BY A SYSTEM FLUSH
ALSO THE ADJUSTMENT ON THE BLEND DOOR COULD BE OUT OF WACK
I HOPE THIS HELPS

As I said , in the original question... I replaced the heater core, flushed the engine and radiator , and replaced the thermostat . I believe you when you surmise that the coolant is not reaching the proper temperature ... but my question still remains as WHY? The blend door seems to have a good seal gasket and is closing tightly and all vaccuum connections behind the dash board are secure. I put another reliable temp. gauge on to the engine and received roughly the same reading as the one in my instrument cluster.
I was wondering whether the small offshoot hose , that I mentioned in my original question , had a bearing on an internal sending unit that I am not aware .
Whadduhuthink , eh ?

IN YOUR ORIGINAL QUESTION I DID NOT GET ANY OF THAT PREVIOUS INFO THE QUESTION I GOT WAS:

NOW THE NAME OF THAT PART IS THE PIPE TO ENGINE HOSE AND IT COULD ALSO BE THE CULPRIT
AS TO WHY THE COOLANT IS NOT REACHING THE PROPER TEMPERATURE ,IT MAY BE AN AIR LOCK IN THE SYSTEM IT IS THE ONLY THING I CAN THINK OF THAT IS LEFT

i HOPE THIS HELPS OUT

I have this vague suspicion that that pipe may be the location of the airlock (if that is the problem ) so as soon as I can shovel a path through the snow to my Mustang, I'll try to evacuate the airlock if it helps - I'll let you know because (as I surf the net) I find that this is a common little nasty that no-one seems to have solved.
Always optimistic,

OK GOODSPEED TO YOU
