Ok so i have a 95 3.4 l (replaceing my 94 ttop 3.4 that my girl got hit in )
now i have started to work on it replaced map sensor, cam shaft position sensor, temp sending unit, crank position sensor, calipers pads breaks, air filter, all fluids (oil, trans, coolant) new radiator fan motors.
now previous owner did new battery new egr valve new plugs and wires.

my problem is that when in over drive i get no acceleration at all and will shake if over 60 and under 2.5 k rpm also when in drive if i am at a full stop the car sputters but idles perfect when in neutral. i loved my last camaro and m hopping to get this one runing as mint like the last one (that i kept as a complete parts car by the way)
its throwing no codes by the way, thanks for the input

 

Were the injectors cleaned? Fuel pressure checked? is there any sound signaling the fuel pump could possibly be failing? The shaking could signal worn shocks, bushings, ball joints, or any other suspension components. I recommend cleaning the IAC and maybe running some sea foam through it to clean any deposits that were built up over the years

 

Sounds like you may have an issue with the trans or torque converter when your in drive but stopped what are the rpms at

 

if its not above mention replace them coil packs. when bad they will cause rough vibrations in overdrive.

 

fuel pumps are issue with these cars.Just found out mine was bad after repairing half the car.Rent a fuel gage for the pressure if low change pump.Theres a cheats and seems to look appealing to my style.

 

agree with ill, have the injectors cleaned and flow tested, not very expensive. what plugs are in the car now? may be a good idea to take them all out and see if they are all in good shape.

 

ok so fuel pressure is at 48 psi idle is at 1k and when foot is on break it dips slightly below abd seems to bog down (dosent stall just bogs)

I plan to check the plugs and wires and just replace them this week

in regards to the tranny it shifts fine as long as i am a) over 2.5k rpm or not in overdrive

and any recommendations on how i can check the coil packs I know the ones from other car are good so i could just swap them.

and i did run seafoam through already forgot to put that in original post

 

seafoam is going to help injectors that are marginal, if a major buildup of crud or failing its not going to help. the process can also foul your plugs so if your going to seafoam do it before you change plugs. if the plugs looked fouled (all black) check your 02 sensors for fouling as well. your idle is high, are you hearing any hissing? check hoses look for any vacumm leaks.

 

so 1k idle is high???? i am replacing plugs noticed a small oil leak and what looked like almost not noticeable smoke coming out of oil fill area. also has now started a single samll backfire when i started and put into drive today hopeing i dont have to swap the engines.
not sure if maybe a bad head gasket or a blown seal thoughts???

 

I did the seafoam I'n my 95 3.4 and it did great.But make sure to check your IACV after & clean.Noticed mine got clogged after lol.fuel pump job for me good luck tho
