Hello All,
This is my first post here. Unfortunately it comes with a problem lol.
So I picked up an automatic Fox body with 78K miles a few months ago bone stock down to the smog pump with the intent of going 5 speed and restoring it to its glory. With that, The car seems to have developed an intermittent stumble.
The car idles like a champ and actually drives very good with the above exceptions
When I picked up the car I did the basic tune up things
-- cap rotor
-- Accel coil
-- plugs
--performance wires
-- 140 amp alternator
-- replaced the fuel pump and filter did a fuel systems flush.
Then I added
--BBK CAI
--3:73 Gears (whole real axel seals and bearings replaced also)
-- off road H pipe
-- FLowmasters
This issue has come and gone since I bought the car but seems to be hanging around now.
under acceleration the car stumbles here and there and seems to lack low end grunt.. at times when i take off it seems to struggle at low end almost like the car is missing, then it goes away slightly or completely at cruising speed, but comes back when the car starts rolling again.
when idling i can rev the car and around 3K then needle bounces and seems to hesitate as if it hits a brief wall and then continues (if needed I can upload a video).
I ran a KOER and KOEO test with an OBD1 scanner and all that was bad was the IAC which I replaced and the code went away.
SO at this point I am at a bit of a loss. I am starting to think the TPI module or Distributor may be to blame
But before I start throwing money at it I'd like to know a few things to check. Even though the car is an automatic, i'd like to think it should have more balls then it does LOL
appreciate any insight from the 5.0 gurus
