It could be either but you might want to check the plug wires and change the plugs if it has not been done in the last few years.

We just purchased a 2002 Ford Escort. Tonight, when starting the car, it ran very rough and then died. We started it again and it ran fine after that. It has happened twice and it has only happened when...


Could be a idle air problem. The injector could be leaking when you shut it off ..Try some injector cleaner see if it gets better..The idle air shouldnt run rough just idle real low or sometimes it will get stuck and idle high....Are you losing any antifreeze..If you are the 2.0 SOHC engine bad about leaking antifreeze into the cylinder and makes the engine run rough until it burns it out..See if you can see the smoke coming out when it happens..White smoke indicates antifreeze,,Black smoke indicates fuel..

Rough idleing after pressure wash engine and fuel injector clean


Hi,
I'm assuming you added fuel injector cleaner to your fuel tank rather than using a direct pressure cleaner through your fuel injectors.
When a solvent/cleaner product is added to your fuel tank, carbonaceous deposits (basically the dirt and gunk accumulated over years) are flushed through the fuel system. This can cause major problems if the contaminants manage to enter your fuel pump and make their way past the seals. This can and has damaged good fuel pumps. Downstream of the pump is the fuel filter - once deposits reach the fuel filter, they may block it and reduce fuel flow. The next major problem areas are the injectors themselves (rather sensitive to dirty fuel) and the engine.
Fuel injector cleaner is not a product I would recommend using. Many major car manufacturer's have recently issued memos to repairers blacklisting the use of cleaner products due to the downstream damage that may potentially be caused by them.
You should replace your fuel filter once you've finished using the tank of injector cleaner. This is most likely the problem (and could have probably used a replacement anyway). I hope this solves your problem. Otherwise you should check your fuel line pressure to ensure the pump is supplying what is required. Failing this, your injectors are probably the next most likely culprit. By this stage, things are starting to get expensive so lets hope the problem is just a blocked filter!
On a related side note; pressure cleaning an engine can sometimes cause water and soap to push down beside the spark plugs in a spark ignition engine. Sometimes this will cause the engine to run a little rough until the heat of combustion burns the contaminants away.
Hope this helps, Sherwin

Runs rough and engine light comes on


coil packs are very common on that car.
if 2 cylinders are misfire ,one pack is bad.
get a tune up,change the fuel filter and clean the throttle body,put an additive in the fuel to clean the injectors,.
if there is problems,get a scan doneto see what code is triggering the engine light.

Car will not start without spraying fuel into intake cant tell if fuel pump is running is there a reset switch and where is it located its a 1997 eclipse 2.0 non turbo


there is no such reset switch located in the car. First turn your key on and listen for the fuel pump to pressurize the lines. Then check to see if the fuel is leaking from the  filter. If it is you may have got the connection wrong. If thats the case your engine is not getting the proper fuel pressure to run. Hence its sucking air. If that does not work you might have a bad fuel pressure regulator sensor that is bad. Its located by the TBI. Reference a Haynes manual for replacement.
also if you did not fill the new filter with fuel then you have air in you system and engine will not run. so try taking it off and filling it with fuel and then replace it.
--------------------------------------
turning ignition on removes air from fuel lines and primes the fuel system. filling fuel filter with fuel is irrelevent, as lines need to be clear of fuel upon installation. leave ignition on after installation for roughly 30 seconds-one minute. this will prime the fuel lines and remove air and most water from the system. if problem continues, fuel injectors. this is a common problem in 90-92 camaros. if cannot start car, you'll need to replace every injector, as it's not cost-effective to diagnose every injector. roughly 300 dollars in quality parts, roughly 4 man hours of labor. if rough start that requires push on accelerator (try this), run the car with fuel injector cleaner. this should salvage you injectors. if this helps proformance, starting, then for the next 3-4 full tanks of gas, add stp injection cleaner for every tank of gas. be careful, as this does not restore your injectors, but it helps clear away deposits which are common in multi port injectors.
