Hey i did a engine swap on a 98 sunfire GT 2 weeks ago. it ran like a bag when i first started swapped IDI and coil packs and got ALOT better.

the car just runs RICH at idle. once you take the car off idle it runs amazing.

any ideas?? i changed IDI and coil packs, and changed all the cracked vaccum lines.

i swapped alternators too (found out his was done)


thanks guys
