sr20det problems

[turboant]

First off my mods are:

blk top sr20det s13 with a 255 walbro fuel pump, 300zx tt fuel filter,
3 inch with no cat.. and thats all for mods now for my little problem:

My car does not like to pick up until 3500rpm and when i push the all the way to the floor it takes a long time to get to 3 and then after 3 i can sit there and rev it and it revs fine. it just has really bad lag from idle to 3000rpm.
i checked the timing and the timing is at 15deg. and idle, and checked the teeth on the timing chain and its checks out good.
i tried different maf sensors and still the same thing.
changed ecu and the same thing....this is just getting really irratating. so pleae help..any advice would be great!! thanks

Check your Throttle Position Sensor Per FSM

well i have the pfc hook up now and i checked the tps ant it say its at 0.40 to 0.41v and this is with the car on but not running

ok i change the Throttle Position Sensor .45 and change the knock sensor and all vac line to new ones and i still have this problem.

o2 sensors the next thing id check. Is it hesitating and smoking black smoke at the same time? Also what spark plugs are you running and whats it gapped at?

LOL @ the plg for buying his spark plugs. :axe:

Lots of things can cause a hesitation, you said for sure that your cams are timed right? You didnt just count the top correct?
