Default Pt, jerking and water leak

2 problems with my 2002 2l cruiser is when it warmed up and it's at low rpm's it will jerk untill the revvs reach 2.5k or more, but when it's cold there's no jerking or hesitation at all .. ?
Ive had the car 3yrs and it's always been like this but I'm looking to sell and I'd like to fix, ive cleaned the the throttle body, It had new plugs n leads but it still does it .. ?
2nd ploblem is that it's loosing coolent, There's a stong smell of coolent when the heater is on and the car steams up inside, When i park it from it's 20mile journey home from work you can hear a hissing sound from front end near the radiator but Ive been under the car and there's no sign of the brown stain to indicate a water leak anywhere near or on the radiator so is there a common place on the pt for water leaking ?

I don't have any suggestions about the jerking and hesitation, but the loss of coolant sure sounds like you have a leaking heater core. Check the carpet and see if it's wet in the foot well of the car. Replacement of the heater core is labor intensive and expensive. 8-12 hour job, depending on the shop and if they've done a PT before. Good luck with it.

We need more information on your PT Cruiser?

Does it have an automatic or manual transmission?

Did the previous owner say if there any work done to the PT Cruiser before you got the PT Cruiser?

Is the engine light on and if so what are the engine trouble codes?

What was the new spark plugs gaped to?

Has the IAC and MAP sensor and the wiring going to both been checked out?

Have you had a battery load test done with the battery in the PT Cruiser and fully charged? The PT Cruiser is sensitive to voltage drops. And check all your battery cable connectors for good contact.

On the coolant leaking issue I would suggest you have a coolant pressure test done to see where the coolant leak is coming from.

It's a manual
Nothing from the previous owner
No engine light or codes as i would of said
Spark plugs gap were checked when i put in, there's no difference in the car between new and old plugs.
Map wires havent been checked but if they were faulty then surely it would jerk when either hot or cold and below or above 2k rpms.

It's a 300 quid car so not wasting money on a pressure test.
Passenger carpet isnt wet

Good luck trying to take care of the issues without any funds.

There's plenty of funds, but it would ridiculous to spend on a 14 year old 300 quid car.
Without a code i dont think you know what the problem is.

Your right! Without buying diagnostic tools to find the problem I probably won't find the problem.

Many cars have their traits, Landrovers have coolent lose usually from a certain place, Saab 2.2 diesels have cold start problems due to air leaks or Fuel pump , Alfa diesels have missfire problems usually due to Number 3 injector connection fault ect ect and all these are problems known to people who claim to be Knowlegable who know their brand and dont need a diagnostic tool.
You are not 1 of those people so probably best not answer if all you can do i state the obvious by saying go and get a diagnostic, the whole point of asking on forums (well for me anyway) is to eliminate all possibilities before having to take it to a garage or having a diagnostic.
Please dont reply as you're not knowlegable enough.

To be fair i dont think you'd understand even if i did find 'That' person as you've failed to understand or Ignored what I've previously wrote.
Reading through your posts you're only good when someone has a code and you can tally that code up to it's problem other that that you're not much use.
You've ignored that there's no eml and no codes, you've ignored that It's only when warm but adviced a connection which wouldnt limit the problem to only being warm would it, But then you've replied that there's no funds which again is a wildly inaccurate statement, so.. as i said , you're not very knowlegable and more of a hindrance than helping, stick to a code mate and let the old school boys work it out without having to be told.
