1992 Ford Ranger with the 4.0. Extra high idle at cold start-up followed by almost stall extra low idle. Then it chugs for the first 50 ft. Gets better as it warms up.

Clean the idle air control valve or replace it and check the readings on your engine coolant temp sensor. Wrong temp reading really screw up the air / fuel mixtures

My ninty three olds royal has a chect engine light that comes on and off. what can I do?

problems can range from the gas cap not being tightened enough to massive engine failure, but if it's on and off it's most likely a mass air flow sensor problem. turn your car on and pop the hood. search the entire engine bay for leaks in your exhaust system. A good sign of a leak is engine sludge when you change your oil and air filter's getting clogged and dirty significantly faster than normal.

Fuel consumption is high and want to know what we should check

Sparkplugs, leads, clean air filter, tyres pumped up, brakes not dragging.
Basically , the cleaner your fuel burns, the better the economy, so a good spark and correct air/fuel mix are the trick.

Driving normal, at 80 kms, car seems to studder a bit, (gas wise) engine light comes on. Stop car, re-start, everything fine, no engine light, at 60 kms, fine, get up to 80 km, engine light comes on and...

First try replacing air filter if not done recently $30, next consider bad fuel put in fuel from major oil company from station with many patrons.Then you need to look at fuel delivery system including fuel filter and furl pump. But first try the 2 things mentioned.

'07 Tahoe; check engine light on steady. Just came

Have a dealer or garage check your Oxygen (O2) sensor. As a quick fix, try disconnecting and reconnecting your car battery. Sometimes this will reset the check engine light.Good Luck!
