I992 Ford Taurus hesitation during normal acceleration @ all types of terrain

My car hesitate (misses) when attempting to merge into traffic on freeways, and during acceleration or change of speeds after I have attained driving speed. The engine does not shut down. It just vibrates or stalls or hesitate until it finally get up to speed. After that it runs fine. The hesitation only occurs when I ask the engine to give me more speed. I have been told something is wrong in the front end. The drive axles are less than two years old. My car has 61,000 miles on it. YES, 61,000 miles. This is why I cannot accept the diagnosis I have been given. This car is not beat up.

I believe it is fuel starvation, or electrical breakdown. Moreover, if this car has the EFI system, I think it does, it may be the computer that controls the fuel injection system.

Before I allow anyone to tear into the front end of this car I am seeking information/advice/knowledge from anyone that knows about this problem with their Ford Taurus.

Oh, I almost forgot. CHOO CHOO! While sitting/parked, I can bring the RPM up until the engine start choo chooing. I have been told that is the governor preventing an over speed. While that may be true, but not in my case. This is something that just started two weeks ago. I maintain my car myself and I have brought the RPM up many times and this car has not been Choo Chooing like it does now.

Finally, I maintain a good car. That is why I do not believe it is in the front end. My drive train is in good condition. For this reason I believe it is fuel starvation or electrical.

I need HELP/ADVICE. What can I do about/solve this problem?

Please email me your response.

Thank you.

How much maintenance has been done? For a car that old heres the short list:

plugs,wires, fuel filter, air filter

check vacuum hoses for cracks/leaks. clean IAC CHeck codes from a code scan.

What motor do you have? Losing any coolant?

How about C.E.L. being on ??????

If not it's usually dirt related like MAF or IAC

And no, your front end cant cause an engine misfire

Whit a question like that I wander about the "maintenance" that you performed

If you are confusing a misfire with a shudder or vibration it can be your front end Check your tire wear and driveshafts

Have you checked your fuel line and had it cleaned. I had the same problem on a 92 f150 a few yrs ago. The subtle but noticeable hesitation when you press the accelerator. I had the fuel system cleaned in a garage, with a machine.( don't know what it is callled) The mechanic had to remove the fuel lines and reroute them into this machine and then back again. The machine takes about 40 minutes to do its job. When it was done, the entire fuel system was cleaned. injectors, fuel lines, etc. And the hesitation was gone!! I had the truck for a couple years after that. Never saw the problem up til I sold it. It may not be the solution in your case. But your description sounds just like my problem.

Good Luck,

are you the original owner?do you know for SURE the true mileage?how about an egr problem.disconnect vacumn line/electrical plug and (egr)see if problem still exists.do you do any auto work yourself?about the choo choo thing.i've noticed on alot of newer(10 yrs)F/I cars that when you sit and try to hold high rev they go into a hickup fit.always wondered about that.

Hi Bob; Thank you for responding. I do not know what CEL means. Therefore, I cannot answer your question. We do agree on the rest of your statement. The Drive Axles have less than 1000 miles. I took the car back to the shop that replaced the drive axles,and we put it on the rack. They are installed correctly. We test drove it and checked the air pressure in the tires. They could not find any problems. Yep, not even the hesitation. I am a shade tree mechanic, aircraft mechanic for twenty years in the Air Force. I maintain a good car. That is why I know it is not the front end. DIRT! never thought of that because FORD just tuned it up about 7000 miles ago. I asked them to change all filters and fluids. I hope they did. No, I am not confusing a vibration with a misfire or hesitation.

Thanks anyway. You answered my question about the front end. That is great. Thanks again. F-G

Hi Vgatehouse: Thank you for respsonding to my question. You agree with me. I thought it was a fuel starvation or electrical breakdown after the engine warmed up. To answer your question, no I have not, but I will now. I think you are dead on as it relates to fuel. I will find a shop that specalize in fuel injection systems and have them clean it out. I will not take it back to FORD. Thanks again.

Hi Oldkid;

Thank you for responding to my question. Yes, I am the original owner. Yes, I know the TRUE mileage. It is 61600++ a few. No, I only change the oil and filter. I will have my EGR system checked again. Less than 10,000 miles ago I had FORD do a complete tune up, changed all fluids and filters. WHY, because I had a Check Engine Light that kept coming on. Whatever they did cleared up that problem. But less than 10,000 after I started getting this hesitation. I think/thought it was/is fuel starvation. However, you suggest it could be the air or breathing system(s). I will check that out.

Thanks again for your response to my question.
