How can I clean my 2002 Ford Focus's engine?

[geon]

I just bought a 2002 Ford Focus and the engine is all dirty. I am thinking of pressure washing it when the engine is cold. Is this a good idea?

Also, my engine hesitates when it is not warmed up. What should I do? I plan to change the spark plugs, change the air filter, add fuel injector cleaner to the gas, and maybe change the fuel filter. Will this solve my problem?

Also, my automatic transmission slips when I am between gears. For example, first gear works fine, but it slips before going into second gear (I can press on the gas, and the transmission doesn't engage right away- the engine just revs up). Is this an electrical problem?

Why would you buy a vehicle with all of these problems without buying an extended warranty????? To clean the engine, You need to buy an engine cleaner at a parts store. Just make sure the vehicle is running when you spray it down with water!

First, I agree with knox. Didn't you test drive the car and get it checked out by a mechanic/knowledgeable friend ? Also engine cleaner and a garden hose work pretty good. Extremely dirty area might require 2 applications.

All the "tune up" things you mentioned are regular maintenance items and if them have never been done, you should take care of it. Will it solve your proble ? Maybe. Most large auto parts store will pull the Diagnostic Trouble Codes (DTC) for free.

As for your transmission issues, pull the dipstick. If the oil is dark red/brown (not bright cherry read) and/or is smells burnt your probably going to need your transmission rebuilt soon. If it is an electrical problem, the DTCs will tell you.
