stock air box

[zkyl1n3]

I have a 1989 daytona cs. 2.2 turbo II. When I bought the car It did not have a stock air box for air filter. It had an air flter attatched to the inlet side o the turbo and the actuating box behind the battery wasnt hooked up because the airbox wasnt there. The vacuum hoses are topped off going to the airbox. Ive been reading about idle controll and all of the vaccum hoses(still havent found a good diagram to tell me where to hook the vaccum hoses up to and whitch ones are pulling or pushing) and i havnt been able to get the turbo to spool or motor to idle steady. Ive been trouble shooting and ran new vaccum lines. checked for vacuum leaks and i dont think i have any. any ideas on weather i need the stock airbox, if i need that computer map box behind the battery and if that would stop my turbo from spooling. The motor will rev through the rpm range with out backfire or missing if i give it gas real slow but if i floor it it falls on its face around 25 oo rpm. It sounds like its getting gas but with out that actuator its not getting the correct air pressure or readings to give it the correct air. I cant find a car in a junk yard to pull the air box from and cant findone on ebay. Please help!!

a missing airbox wont cause yur symptoms,
altho bodged up vacuum lines might

the box behind the battery is the ECM;
stock, intake air was ducted thru that ECM housing to cool the internal components

pretty common for TDers to bypass that without problems,
altho an extremely hot environment (e.g. Texas in the summer in stop&go traffic with the AC on) might cause the ECM to overheat;
this could be remedied with a small 12v 'computer' fan to cool the ECM

ps you need to check for codes to help diagnose

Fault Codes - Mini-Mopar Resources

I bet you have codes, no doubt a code 13 in there.

I would take off the air filter and see if the turbo spins freely, there should be a line off the compressor leading the air filter up by the battery. Having the filter right on the turbo is bad.

Make sure boost control, fuel regulator and the map sensor are hooked up well. Don't worry about EGR lines.

Our FAQ section also has the fault code list, Russ' site breaks down each code nicely however.

BTW the air filter is not the real problem..
