This is indicative of a problem that may not have a simple fix....

A blinking Check Engine light is signalling that there is something happening that could potentially destroy vehicle catalytic converter or other,related emissions devices.

Anything from a bad spark plug, plug wire, ignition coil pack (if coil on plug ignition system) to a leaking/non-firing injector to a dirty air filter could be the cause. Get it *towed* to a shop for professional computer diagnosis, but try to not drive it until resolved - if you can help it.

Can be complex, could be simple... This happened on a 2.2 liter Subaru I owned. The fix was a new set of wires as No. 2 cylinder was not firing and was dumping unburned gas downstream into exhaust. It made my check engine light flash like Christmas. :D

What is wrong when it's cold and my 1998 Trooper powers down with the ABS light, the battery light, and the four wheel drive light blinking


that is called a STALL.
the engine was running , but now its STALLED.
and all lamps come on that is a Feature of all cars. (modern)
the that is the lamp self test. same as when you first turn on the key.
the operators guide explains all that...........
so the real question is why it stalls.
it means the engine is running so bad the EFI brain could not avoid the stall, it tries REAL HARD not to stall.
we do tests to find true cause. but usually its this.
1: engine never tuned up. the 60,000mile service POINTS skipped.
hark it fails. (99% of all old cars do that, due to skips)
2: LOST spark , see #1
3: lost fueling, see #1 filters. or worse.
4: flooding, over fueling. more tests.

got tools? or just want guesses?????

Engine skipping on a buick Rendezvous


When the check engine light is on, the computer has found a problem that can affect fuel economy or emissions.
When the light flashes the problem is serious.
You need to get the computer scanned for trouble codes to proceed with testing.

Start with checking your tail light bulb if the front one is working. If it isnt the rear bulb its the flasher itself.
