thx all

lil mike

 

i think i heard it was a vacuum problem as well let me check some links and as a few people bump it for ef's

 

allright ty

 

any more ideas?

 

is it throwing a code?

 

your in limp mode, check codes. make sure sensors are plugged into correct locations

 

its throwing codes 4 and 14

 

crank postion senser and elc air control val i think thats the right ones

 

Code 4 - CKP is causing your problem. problem is in the distributor or in the wiring between the distributor and ecu

 

ty sir
