another sn95 5.0 stall
We'll start this out simple.
5.0 5 spd
k&n airfilter
exhaust is non cat straight pipes (block offs, sensors and pipes properly welded or installed)
smog pump removed
short belt
Now bought the car for $2400 dollars. it ran a lil rough and stalled off and on. the rough ride was the harmonic balancer. replaced. car continues to stall. map, maf , iac, pcv valve, fuel pump, and altenator all checked and or replaced. car continues to stall.smog pump and egr removed, blocked off and egr bypass installed. car starts running better. but not fixed
when you come to a stop the idle twitches, then spasms from 800- 400 rpm, then stalls. also if it sits and warms up, within 10 mins shes revving 800-400 and then stalls
decided to replace dizzy.(while car was running, hood popped, turned dizzy back and forth barely and car didnt die or stall out) car runs 100% better... still stalls..( dont remember having this issue in my 3.8 or 3.8sc...) ok tired of it, take it to a shop
new symptom. driving along fine at 50 mph car suddenly 0's out on tach and dies, try to pop start it.. no good, feels like back axle trying to lock instead. pull over, pop hood, nothings broke, no leaks, start car.. its starts, runs fine. twitch..
ford says they cant look at it or anything until the smog pump is replaced , because the car has to have that to function properly..bs..
read all the forums not just this one.
have done draw tests, vaccuum tests, replaced sensors, cleaned everything. but stall wont go away. pleae any help or suggestions.. otherwise im parting her out
