Diagnose where the problem lies. Car starts and runs, then usually at idle stops and won't start without spraying ether into carb.

Already changed fuel filter, plugs, wires, cap and rotor.

SOURCE: Carb loading up and engine surges at idle

I called an old mechanic friend who confirmed what I suspected. The engine control module which controls timing was the culprit. I replaced the defective unit, and the car runs like new.

SOURCE: Idling Problems

Note that all cars don't have the same symptoms as stated in the following procedure to cure your problem.
Here are the most common causes of surges, stalls at stops, low erratic idle speed, rough idle and engine hesitation, 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.

SOURCE: Rough idle at low rpm

Give it a compression check and if all within spec or the same then come back to me and we can take it from there...it sound like a simple problem.

1986 Toyota p'up starts, but won't stay running once i left off gas pedal


first i would look for a vacuum leaks get it as close to idle as you can when cold and spray carb cleaner around and also check to see if the egr valve is stuck open this will act as a vacuum leak but not detect as one spraying carb cleaner around carb cleaner with change the engine speed near a vacuum leak

My 96 crown vic police interceptor, cranks won't start without spraying starter fluid.. the car won't start without spraying starter fluid into air intake hose to carb...


starting fluid is a thing of the past. dont use it. this car doesnt have a carb, its a throttle body/ electronic fuel injection system. you most likely have a fuel pump or fuel pressure regulator issue. test the fuel pressure, should be anywheres from 35-50 psi

Starts right up, doesn't idle in drive or reverse, dies at stops, seems flooded when you try to start it back up. I have replace so much on this stupid car ad just want it fixed


i am thinking it may be a vacum problem..get a can of carb spray and with it running in park spray the carb cleaner around all the vacume lines when you notice a diffrence in the way its running...it smothes out ..rpm change etc check that area for the leak

Car would start idle really bad. Take off really bad spitting and sputtering then smooth out and be ok to drive. @ stop and start again did fine. It was hit and miss. Changed plugs and wires, still runs...


Fuel pump may not supply enough pressure to run engine, but it could be a pluged fuel filter as well. you should get the code pulled out of the computer this will tell you exactly what is wrong or at least narrow down what is causing the problem. It could also be either bad gas with water in it or bad timing or wrong firing order.

What would most like likely cause a 1995 dodge ram to idle rough and die when you slow down or stop?


Usually a rough idle caused by a vacuum leak, check your hoses and thottle body base gasket. It could also be the idle air control valve.

Try setting the idle speed up a little--the racing cam in this engine will not allow idle very well at best. An improvement in the ignition system performance will help starting. This engine wasn't made to poop around in traffic.

Buick lesabre nightmare


Need to get a scan tool and look at the data stream while it is running for alot more info.Also any trouble codes.Sounds like initially,the engine isn't getting any fuel.I would have a pressure gauge connected to the fuel rail on the engine,so i could monitor the fuel pressure while all this is going on.Items to look at on the data stream would be timing,what timing is the PCM commanding for the engine.Also,have you checked for continuos power feed to the coils during this no start condition,and fire at the plugs while cranking.You could possibly still have spark,but maybe it is extremely weak?I have seen bad ignition switches cause weird problems before too.Many things power up through the ignition switch,just a thought.Have also seen bad PCM's cause strange problems..38 volts is a little on the low side for GM.Usually see those at,at least .50 and up,and rise steadily while pressing the throttle,up to just under 5.0 volts.Potentiometer with 5 volt supply.Vacuum leak can be checked with engine running at a steady idle speed,spray brake cleaner all around the intake manifold and listen for engine speed change.
