hi guys,

had a bit of a search around but have struggled to find what im looking for.


i have just put a 20v slivertop 4age into my suzuki sierra.

the motor is running sluggishly, rough and rich.

i have swapped the afm, cleaned the o2 sensor and cant find any vacum leaks that im aware of. the motor was running fine when it came out the old car so im assuming the timing hasnt changed somehow.

ive checked the computer codes 62, 63 ,64 are being thrown, which from what i can find are for the auto solenoids, however now this is a rwd they dont exist. would this cause some sort of limp mode?

it idles lumpy and rough and doesnt seem to clear up when revved and wont rev out much. im assuming maybe to about 6000rpm (no tacho wired up yet still a few bugs)

anyone got any ideas? cheers
