Hesitation off the line
I just bought a 1992 coupe with auto trans and 144k miles on it. I noticed it has a pretty good hesitation off the line .... is this an easy fix? Should I take it to a Mechanic or should I try to attempt it myself. I am no shlep around cars but drivability was never my thing.
Thanks

The first thing I would do with that many miles on it is replace the air
filter.
I would go to the dlr and get a rebuild kit for the throttle body about 22 dollars and some carb spray and clean it with out taking the tps off and see if it helps.

Check the MAP sensor and the vacuum line that connects to the sensor. Make sure that it isn't collapsed or pinched. The sensor could be slow reacting so that means that the ECM will be slow to give fuel enrichment. Your engine has a speed density fuel strategy which means that the ECM relies on the signal from the MAP sensor as an intergal part of its fueling strategy. Another problem source could be the TPS sensor. If its not working properly the ECM won't know where the throttle is.

Thanks guys I will be trying to tackle a few of these things this week. I looked into the throttle body the other day and it was filthy, Ford used to sell a foamy spray injector cleaner that was awsome I am gona see if I can get some of that to use.
