SOURCE: Hesitation problem

try cleaning the inside of the MAF sensor and do the following procedure as well.
Here is the most common cause of surges and stalls at stops and low erratic idle speed and rough idle, it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

This is not a do it yourself project. It sounds like part of the front suspension has broken loose. It is possible that it is a wheel bearing or a drive shaft. Anytime you dissamble the steering wheels, you stand a good chance of losing control after you put it back together. This is one where a trusted mechanic needs to get involved.

My 1994 cadillac Fleetwood brougham power steering pump with electric variable orifice is not working is there a bypass system i could use?


Hi there, sorry to say I do not think so. If the power steering system is specialised, designed for the car, there is unlikely to be another backup system to substitute for it when it breaks.. If the PAS pump is broken then it is a matter of replacing it. Please check the link below for sellers of recycled parts

Or you may want to obtain a new part from a motor factor/parts retailer

I HAVE A 91 SEDAN DEVILLE.4.9 PORT FUEL INJECTION V8. I HAVE PLENTY OF ACCELERATION FROM STOP TO 20-30MPH. BUT WHEN I AM AT ANY CRUISE SPEED AND STEP ON THE ACCELERATOR IT HESITATES AND DOES NOT...


Sounds like a malfunctioning egr system. Too much egr gasses at once will lean out the air fuel mixture and cause hesitation in an engine. Just my 2 cents.
