Had tune up done on my 96 century new plugs,, wires fuel filter to solve a mis fire. Replaced coil pack on same cylinder.

Drive it a little and when you come to a stop light flashes starts to shimmy hard.

Where is the oil pressure sending unit on a 1999 Isuzu Rodeo 4 cylinder engine ? On Occassion, after driving for a few minutes, the oil pressure indicator light will flash and sometimes stay on. Usually, if I shut the engine off for a few minutes and restart the engine, the light will be off and stay off. Does the oil pump have a screen that may be dirty or partially clogged ?

Sender unit is situated on the LH side(if you're sitting in the\015\012vehicle) of the cylinder block ahead of the starter motor. Problems\015\012with oil pressure are rarely because of a faulty sender. Your problem\015\012starts once the oil has hea ... 1999 Isuzu Trooper

I have a 2000 vw new beetle that has an eletrical miss specially when i start the car after being cold.the spark plugs and the spark plugs wires were replaced but the miss is still present.one of the coils in the coil pack is a little bit weecker then the rest.the question is why when the engine is cold the miss is worse and the check engine light keep flashing untill the car is warm than the check engine light would stay on.and what is the solution. thank you

Check the resistances of the coils, check both hot and cold, If you have a greater variaton on one of the coils then the other change that coil. The reasoning does not always have to make sense. Logically the coil would be weaker the warmer the engin ... Volkswagen New Beetle

Rough idle I just changed my spark plugs and the EGR valve in my '96 tahoe and finally got the check engine light to turn off.

The check engine light would stay on and sometimes flash--the car would run badly. I replaced faulty spark plug wires and the ignition coil. Now the car runs VERY poorly and the check engine light flashes after about 20 seconds. How do I reset the ECU? Is this the problem?

The wires and coil was a just throwing parts at it ,for no reason. Try disconnecting the battery to see if the codes clear. You will need to scan for the code if it comes back and proceed with the proper diagnotics to find the issue with the engine p ... 2000 Hyundai Accent

I heard a pop as I was driving and the engine light came on and subsequently started to flash. I changed the plugs and cleared the codes. Two days later, the light come on and started to flash again, and I changed the coils and cleared the codes. The next day, the light came on flashing again, and I performed a compression test, recording 150 in each cylinder, and cleared the codes again. Two days later, the same codes returned. I am now considering a timing belt job, but I need another opinion.

First before going into it that deep, what year and model? Get the codes instead of just clearing them and let me know. I can advise you on how to proceed without throwing parts at it. ... Chrysler PT Cruiser

P0300 code reading on Chevy aveo. Engine light flashes and stays solid intermittently. While driving on the freeway, engine suddenly cut off. Tried to restart. Could hear the starter turning but engine would not respond. After a few minutes engine started, but engine light was still on.

Pull out your spark plugs. Change them if dirty. There might be a problem with the fuel trim, thats causing spark plug to foul up prematurely. A stucked open EGR valve can also cause a multiple mispfire code(P0300) but then it would be accompanied by ... 2005 Chevrolet Aveo

I have a 99 marquis. My engin light has been on for awhile because of an evap leak. When I was driving 70 mph on the freeway it started flashing. I tried counting the flashes but I was driving so I might have miscounted but I think it flashed about 8 times. Is that a specific code? Please help I don't have the $90 bucks for a diag test. Also it does have a miss in it would the flashing indicate what coil is bad?

Not a specfic code, but it means the problem is more serious and needs to be repaired now. The flash was probably from the engine misfire. Scan for codes and repair it before further, more costly damage occurs. ... 1999 Mercury Grand Marquis
