Hi there. Novice. Have done some research but can't seem to find exactly what I am looking for. Appreciate any help :)
I have a 1989 Jeep Grand Wagoneer (AMC 360 5.7L), previous owner installed Howell EFI kit https://howellefi.com/product/k247jw...-wagoneer-360/
Also has HEI distributor upgrade.
Issues observed:
1) fuel pump primes but still hard to start.
2) does not rev high and then settle.
3) often stalls after starting
4) can sometimes smell fuel after starting.
5) pops, sag, stall after accelerate off idle (intermittent).
6) error code 33 (low vac pressure) can be read from the engine warning light (paper clip trick) ...
Looking to use something like ALDLdroid https://www.aldldroid.com/ but this needs an ADX file and I have no idea where to locate the right one.
Appreciate any help for a novice looking to fix and tune my favorite car...
ECM is GM PN 1227747
Thank You
