Hi

i have had my a 93 TBi astro off the road for nearly 6 months now

been having real troubles getting it sorted, and found your forum so maybe someone can help me

atm its running far too rich, black smoke and heavy fuel usuage

so far what has been replaced:

new distributor whole unit including cap, rotor arm

electric system, plugs, leads

fuel system checked, pressure is right, injectors replaced, pressure regulator diaphram replaced and new coolant switch

oxygen sensor has been checked with multimeter and is ok


any ideas to why its still running so rich??

 

Do you have any codes? Have you checked the timing? Could it be the PCM? How many miles are on this vehicle?

 

we had a code 15 last time we checked, sensor has been replaced last week

gunna do a check again on monday

she has done 80,000 miles

timing has been quadruple checked!

what is a PCM?

 

PCM is power train control module, in other words the computer!
I have a 93 Safari with 205,000 miles on it. It is more dependable then my 2000 Astro!

 

going to check the water temp senders today, see if this is causing the choke to stay open

 

all fixed

was a broken solder on the plug for the water temp sender, simple things, big trouble hey

ty for help

 

Woot! Good to hear.
