94 ford escort 1.9L

Hi! I have a driving problem with my 94 ford escort. About 3 weeks ago I noticed that my car "stutters" when I try to accelerate. It doesn't happen all the time...it could occur from 30-35 or 60-65mph, after first starting up the car or not until after 30 minutes of driving. If feels like when I press on the gas pedal the car starts to "shake, stutter" and I don't accelerate at all. But I don't have any problems if I keep at a constant speed. Last Tuesday I added fuel system cleaner to a tank of gas...lessened severity of shake but did not stop. Added another cleaner to tank of gas on Sunday. Today, I had my fuel filter changed and the mechanic noticed that a hose wasn't attached, so he reattached it. After 10 minutes of driving the stuttering is still evident. What should I try next?

Your Mass Air Flow sensor may have crud on it

It's on the Air Intake tube
It's after the Air Filter Box, but before the Throttle Body on the engine

It's a little box like thing, the cover of which has these odd safety/tamper-proof screws holding it on

You can get the proper tool, or just cut a slot in them with a hacksaw or dremel and turn them into flat head screws

When you pull off the cover, a sensor should come with it
It almost looks like a light bulb filiment
The wire from left to right should be very, very thin
If it looks like yarn, actually if you can see it clearly (lol) it's got crud on it
A few shots of O2 sensor safe carb cleaner (don't get any on the car) and you should be good

Two things
1) If the Check Engine Light is on, even if it comes on and goes away sometimes, pull the codes before doing this procedure
2) Un hook the neg. battery cable before doing this procedure, and hook it back when you are done
Mostly this is for safety, but it will also clear your codes (which is why you want to pull them first if you have any rason to believe you might have some)

I would check for vacuum leaks (including all vacuum devices), clean the MAF as suggested above, then check the TPS.

Slickshift: My check engine light has never come on. What does "pull the codes" mean?

Icondude: What does "TPS" stand for?

Sorry, I'm just a young lady who knows nothing about under the hood of cars!

Pull the codes would mean hook a scanner up to the computer in your car and read any trouble codes that the computer has stored

If the Check engine Light was on or flashing, that would be the computer telling you it has some trouble codes stored

The TPS would be the Throttle Position Sensor
Part throttle drivabilty problems can be cause by a TPS mal-adjusted, or going bad

I have been driving escorts for ever first be sure your gas cap is on tight then if that does not work it sounds like you have an oxygen cyncer gone bad and excorts have several have it put on the machine to check for which one is bad with a good mechancies book you can normally replace these yourself
