Hi all , I have recently imported and registered a 1987 camaro belinetta v6 . I can't get it to run right , it's fine at low speed but as soon as you put your foot down it coughs and splutters . It's had a new fuel pump , plugs and leads, fuel filter , dizzy cap and arm . I have also stripped and cleaned the throttle body but to no avail . Am stumped with this one any help would be much appreciated . 😰

 

Is there a check engine light on? Check fuel pressure, spray carb cleaner around the manifolds to find any vacuum leaks as well as hoses. Any hissing sounds?

 

Yes there is a check engine light on . The vac pipes look ok but will spray some carb cleaner around it today I've not checked fuel pressure either . Thanks for your help it's much appreciated ..

 

update : have checked all vac pipes and seem ok , also have checked for leaks around throttle body it has a very slight leak from butterfly pivot ( only noticeable with smoke pro ) . fuel pressure ok . also checked timing with a strobe light and it seemed out to me so i have set it to 12 btdc . runs a lot better but now seems flat . i have also pinned out the eobd connector and im getting codes 33 and 34 , map sensor i think . however do these have a map sensor if so where is it , or is it relating to maf sensor ? and what are the proper timing stats ? all help really appreciated would love to get this car right !
