Cold start hesitation

[Zende]

I have a 95 disco with 140k.. The engine starts with no problem, but when I put it in drive it kind of hesitates until warmed up.. I give it gas and it takes a few seconds before taking off quick.. I have no problems like this on warm days and I use 93 octane always..

Prior to this problem I took it to my exhaust shop a few weeks ago and was told I needed 2 o2 sensors, a new y pipe, and right side manifold.. Would the exhaust have an effect on the engine hesitation during cold starts? or could it be a fuel filter, pump or injector issue? I sometimes smell a little gas during start up.

Any feedback will be greatly appreciated!! Thanks

TPS (throttle position sensor) may be dirty....

Thanks, Joey...

Where would I locate the tps and how should I clean it if dirty???
oh, How can I tell if dirty?

Ok, Thanks.. I will definitely try that this weekend.

One quick question, Do I pore it down into the engine or up into the other part? Does it matter?

Which end of hose do I remove?

Thanks again

Sorry, the seafoam part is for other issues, the picture was to indicate where the Throttle possition sensor and the IAC are located so you can remove and clean with some contact cleaner.

Tps Clean

What Would You Recommend Using To Clean The Tps /iac?
Thanks

As always a non-residue contact cleaner (you can buy at almost any electronics store)

Tps sensor??

95 disco, 140k

I checked out the tps sensor and it looked clean to me. any other options???
When I start it in the cold and put it in drive, it wants to die out.. If I give it gas right away it can easily be flooded.. Once warmed up it drives and restarts fine...

Any feedback greatly appreciated
Thanks

It could be fuel ejectors that are starting to go bad or the IAC may be dirty... lots of things can cause this issue. Last time plugs or wires were changed? Air filter, fuel filter... when was the last time the throttle body was cleaned?

This is where I would start.
