So, i was working on the rx7 this weekend and everything was working fine. Have Greddy Titanium Catback, SS 3" Downpipe and Trust Airinx intake. I decided to start installing my boost, egt and a/f gauges and paint the stock intercooler pipes black. So i get everything back together the car off the ramps and start it up. The car smokes too the point i thought the fire deparment was going to come, the engine shakes way more than usual, and when i rev it a lil the throttle sticks for a while before the rpms drop down to idle. The only things i did that changed the car from its running fine condition is: drilling a hole in the dp for the thermocoupler for the egt gauge, take off the intercooler pipes and then i put new plugs in since it was on ramps (however i did the plugs after seeing it smoke so much the first time just to try something). Anyone got ideas, or am i screwed?

 

Check the vac line to the boost sensor.

 

Checked and was unhooked will let you guys know whether that worked or not.

 

stock ic pipes are black plastic... you must have aftermarket pipes and/or aftermarket ic.

 

Reconnecting that should clear up most/all of the smoke and engine shakes.

 

Checked and was unhooked will let you guys know whether that worked or not.

 

The pipes on my are the still stock shape with the real skinny one on the hot turbo side, they were like a plasticy color and oil stained so i cleaned them and painted them black, still seems to smoke quite a bit, going to take it for a drive in a bit. Thanks

 

Did you change your spark plugs one at a time, or all at once? It's also possible that you switched the spark plug wires.

The forum guys are awesome, thanks yuichiror for the help that fixed everything and the spark plugs i did individually cause i know i would mess something like that up. Thanks guys!!!

 

No prob, that's why we're here. Glad you got it fixed.
