Hesitation
The car hesitate on take off. but codes 44 &33 are coming up. If I cut it off and try to start it up again it want. If I put my foot on the gas it will. code 44 comes up for lean exhaust my injector are ohm out at 16.5 fuel pressure is at 38 psi @ idle 44 psi whith key on tps is set at .54 and timming 6 degree i am lost at this piont

If I hit the gas fast it's stall. if i ground the test port under the dash it will start after about 6 times What do you think it could be? stock 305 tpi

 

my techer at school says that hesitation is usually cause by clogged or lazy injectors. but either way it is usually some sort of injector problem(so he says).

 

when it hesitation the fuel pressure is at about 46 psi does it worse under load in gear don't know what to try next

 

lean exhaust ? Makes me think you either have a vaccuum leak , exhaust manifold leak , or a sticky IAC valve.

 

i did see that the exhaust manifold is leaking buy the o2 sensor will this cause a stalling problem? i clean the iac today

 

i changed the tps and the iac and nothing going to try o2 sensor next

 

new o2 new iac new tps new auto zone mass air flow fix exhaust leak what to try next

 

well took car to the shop and they are saying that the injector might be bad ohm out at 16.5 to 16.8 and alldata say 16.35 max
