ok so i took my car out for a ride lastnite for the first time after rebuilding the bottom end. it hesitate really bad, every time i shifted it almost died. so i went to make sure it was in time. so i jumped the service connector before using the timing gun and wow 6 cels.

7 - tps
5 - map
14 - iacv
17 - vss
23 - knock sensor
41 - Primary oxygen sensor heater

Yes they are connected and to the right plugs. if i unhook them while the car is running it makes a noticeable difference. unhook the iacv and it stalls so they are kinda working or something. still hesitating really really bad. any ideas?

 

switch the connectors on the map and TPS....

So the TPS is going to the MAP.... and the MAP is going to the TPS.. Very Common mistake

IACV is prolly the most annoying CEL to get.

Did you wire up a new o2 sensor?

 

map and tps are correct the way they are. i label the plugs when i took the motor out. its the same o2 sensor. all i did was unhook everything rebuild the bottom end and plug and play. now it runs like *** and has 6 cels

 

ok i took it for like a 30 min ride its seems to hesitate more when it gets hot too.

 

bump...........
