Chevy venture stalled

Hi ive changed fuel filter, dropped tank, checked spark and changed egr valve as a result of stalling it wont start after all work ive done im about to change timing chain but every piston seems to fire after cleaning spark plug it started but ran but sounded carbon up from trying to start it so much and being flooded backfiring. wont start again and am changing plugs and gonna scan it as it initially had p0440 code which was egr valve. didnt work after that must be to carbon up im thinking. hope you have solution.

Compression, spark , timing , fuel for any engine to run. Don't forget a stopped up catalytic convertor will have the same effect as you described. Backfiring of course is fouled plugs, bad plug wires, look for arcing from wires when it is dark outside. If it has a distributor check for cracked cap, had my 91 GMC start backfiring then die due to ignition module inside distributor going bad. It would start back up after it cooled for about 10 minutes.

sounds like the timing belt it has a interference engine so if the timing belt broke you could have bent rods and cracked pistons or worse. good luck

DEFINITELY change the filter...It's only about ten times past its useful life. Then check fuel pump, pump relay and fuse. (doubt if you'll have to!!)

SOURCE: '87 dodge raider wont ilde.

My 88 raider did the same thing. As long as I had my foot on the gas pedal it would run but if I lifted off the gas it would die. It ended up being a vacuum line. I can't remember which one (possibly the AAP) but not sure. I did replace the AAP diaphragm and all of my vacuum lines.

1993 Honda Accord loses power,stumbles I pat the gas and it will pick back up check engine light comes on and it will run fine


why not finish the tuneup, spark and air filter.
also the EGR valve is a 50k service point.
if the EGR sticks open, Just before a stop sign driving
this is a sure sign of a stall ,by EGR. failure (clean it)
my pat gas.
so you are really saying, the rpm drops way below normal?
at idle , then stalls.
but the fast right foot saves the stall?
below 400rpm most cars stall. 300 for sure.
the CEL will flash on just at or just after the stall. RPM based action it is.
and if the stall is easy to save?" is it, super easy,? then the ISC is failing, the idle speed controller.
if on the other hand the skipped fuel tune up, its all nasty bad spark then all hope is lost , for ISC and ALL.
do the tuneup first, see the list?

Yea , those crossfire injection vettes can be a bear sometimes . I had dealings with them 84-85 - 86 working as a tech at a chevy dealer . Don't remember much about them , haven't heard anything about them for long time .

How's the fuel pressure ? Have you put a fuel gauge on it ? I would imagine you don't have a Tech 1 scan tool ? What's the map sensor voltage at idle ?

You've already eliminated the spark plug & wireset, distributor cap & rotor.
Sounds like your car needs a tune-up, specifically, the PCV (positive crankcase ventilation) valve, and/of the EGR (Exhaust Gas Recirculation) valve.

Components checked/replaced during a tune-up are:
air filter
motor oil
motor oil filter
breather filter
fuel filter(s)
fuel strainer
PCV valve
EGR valve
spark plugs
spark plug wires
ECM or distributor cap & rotor
cabin air filter
transmission oil filter
transmission oil
engine coolant
check all vacuum hoses and lines

My 2000 chevy venture when is running maybe over 40 mph the iddle starts going down and up, why?


could be several things, like dirty air filter, fouled spark plugs, bad gas, bad fuel pump, clogged fuel filter (probably located on the pump which is most likely located inside the fuel tank.) bad EGR valve, a vacuum leak... the list goes on and on. but most of these would cause a trouble code or service engine soon light to illuminate. if that light is on then you might want to get a parts store to read the codes for you and then repost with the results. good luckl

My 92, chevy 5.7 v8 will start 4 a moment then dies pumping the gas doesnt really help either ive changed the spark plugs, wires & cap, fuel pump egr vavle, checked fuses & it still wont run


Sounds like the fuel pump. it is in the gas tank and rather pricey for the Chev. trucks. easiest to drop the tank and clean area around it really good first.

1992 chevy corsica runs rough,stall or dies after stopping


Sounds the EGR valve and EVP sen is bad even if you tested it. The EGR valve cntrols idle and if carbon up will make the car stall or idle high and low (rpms going up and down) This was common on all cars during that time. I would say replace the EGR valve and senosr. This should take care of the problem. One more thing have the fuel pressure check on the car.
