Help!!!!!!

[lshatch93]

if some one could help me out id really appreciate it

i have a ls b18a in my hatchback, first off it has a crazy idle when i start it cold it will idle at like 2200rpm, when its warm it will idle lumpy between 1000rpm and 2000rmp, sometimes it will idle right under 1000 rpm its wierd.... my main problem is it has a random hesitation when i accelerate it only happens every once in a while... its around 3500rmp when it happens and i give it more throttle it will hesitate and launch if i keep the throttle at the same spot it just boggs and wants to slow down. its really pissin me off i have an idea it might be the tps sensor, but i cant find one around here, auto zone and a couple other car parts stores don't sell them, does anyone have any idea what this could be before i start spending a bunch of money on something that's not the problem??? thanks guys

it could be many different things..I would check the tps sensor,distributor,timing,could be some bad injectors or fuel pump..its hard to give u a definet answer but start by checking your compression on the motor and then open the dizzy and make sure its not moist or wet or needing a cap or rotor and then check your tps and timing or fuel pump..g/l men

time for a new swap muy dude

[bluxberryxhaze]

you got any cel lights on?

[lshatch93]

when the bogging happens the check engine light comes on thats about it

[bluxberryxhaze]

im thinking its your tps. Cause my boy has a b20vtec with a f'd up tps and it hesitates to go when you let off on first but after a while the hesitation stops and rides normal. but you should check the cel light and see what codes come up.

[PinoyDelSol]

Possibly tps, but wrong section to post.

Not at all. But it could be many things! Check your timing, tps, plugs, wires, fuel filter. Those could all cause it to do what you described. Honestly it could be manyyyyy things. But it's prolly something stupid. What ecu are you running?

[CTgoldhatch]

sound slike you got a bad sensor look over all your plugs see why the light comes on and look for a vacume leak

[LS/Vtec]

Unplug your tps and see if it runs the same if so that is your problem. If so your best bet is to buy a used throttle body from someone around your area with a good working tps. It'd be easier then trying to find just the sensor, demel'ing the rivits to flat heads, removing it, putting the new one on and adjusting it. Lol i'd just geta whole new throttle body.

does anyone have one for a 93 ls? id like to find everything if possible, intake manifold, throttle body, sensors ,fuel rail, and injectors, something that came off a good motor, ... thanks for the help guys

[lshatch93]

today i did the cel light and i got 7 and 43 , i found out that 7 is tps, and 43 is a faulty in the fuel system.. does anyone know what it might be? maby injectors? thanks for the help guys

well i have a hatch wit a 0bd1 ls swap and i was having similar problems and it turned out to be the tps sensor,,do wut ls/vtec said and unhook the sensor,,mine ran much better wit it unhooked though,, until i calibrated it
