i just installed a plenum spacer and I noticed that sometimes when the car is warm when i start the engine the rpm's sometimes go to 300 or lower like the car wants to shut off..is this the symptom of a air leak?? after that the car idle smoothly...should i perform a reset? or something like that..also what can we use to clean the TB and for the MAF i have used CRC maf cleaner..thanks in advance.

 

Mine did this too, but I put some little rubber gaskets under the plenum bolts and its fine now.

 

u have a leak.

 

nice...I put the washers that came with teh bolt...Jamez you mean the bolts 6 on top of the plenum or the one around the plenum? also what kind of rubber gasket do you mean?what can I use instead?
