Unease has spread from the backbenches into Cabinet as fears grow of a second and third inflation wave from the planned increases in carbon tax in May and plans to end the special VAT rate for hospitality in September.
In last year's Budget, the Government announced that from May 1 the carbon tax would rise from €33.50 per tonne of carbon dioxide emitted to €41 per tonne.
However, a group of senior Fianna Fáil and Fine Gael TDs are now planning a simultaneous rebellion against the proposal.
Within an increasingly unruly Fine Gael party, it is believed a group of its TDs will put down a motion before the parliamentary party demanding the tax rise be deferred.
Fianna Fáil's John McGuinness said he would be in contact with party colleagues on whether they would support a similar motion.

Significantly, unease is also spreading within the ministerial ranks with one warning: "The messaging of this is appalling. Inflation is running riot and the message from the Government is that it is putting your fuel up again. It should be deferred at least until the war ends."
Another minister warned: "It gives credence to the Sinn Féin claims that we are detached from reality, it is a tangible example."
Another said: "Everywhere you go as a minister you are asked what you are doing to reduce prices, well here we are increasing them again."
Unease is also growing across Fine Gael and Fianna Fáil over proposed plans for a carbon tax increase in May.
One minister, in a blistering critique of his Green Party coalition "allies" asked: "Are they mad? The price of home heating has increased by 50%, petrol is up by 30% and the price of diesel by 32% and they want more increases.
"We need to be cutting prices not increasing them. We are facing a revolt on carbon tax, it is political dynamite."
Anger is also growing over what is perceived to be the slow response of Finance Minister Paschal Donohoe to the spiralling inflation crisis.
Amid calls by Sinn Féin leader Mary Lou McDonald for a €1.4billion mini-Budget, Tánaiste Leo Varadkar conceded to his party last week that the public were "frustrated that they don't feel we have responded with adequate urgency and adequate scale".
Families can expect to be at least €3,000 worse off this year - thanks to a raft of price increases which keep coming and show no signs of abating.
Electric Ireland - which supplies half the domestic electricity market - recently announced further increases amounting to another €520 a year for a dual bill.
SSE announced price rises of 24% in electricity and 32% in gas just days ago.
But those increases come on top of two earlier hikes by Electric Ireland, adding more than €840 overall in a triple whammy of hikes from the supplier which came into effect in August last year and another in November. The third is due to hit this May.
The latest rises will put the squeeze on families, with groceries, heating and fuel, as well as gas and electricity adding up to over €3,000 extra a year - and that is a conservative estimate for some essentials.
The price of buying used cars, as well as rocketing rent and house prices are all also going in one direction, leading to the grim findings of the Irish Daily Mail's research.
Daragh Cassidy, of the consumer website bonkers.ie, said: "It has been a tsunami [of increases] following on from last year when there were at least 35 increases. There's been five so far this year and it's only March."
He fears it is "only a matter of days before others announce a price increase".
Mr Cassidy added: "We won't see prices go down for the foreseeable future, that's for sure."
Prices are rising at their fastest rate in two decades and Central Bank Governor Gabriel Makhlouf warned: "This is the highest rate of inflation since late 2000. We know that many people are feeling these very real increases, in particular across their energy and fuel bill."
Dr Tricia Keilthy, of St Vincent de Paul, said it is "a very worrying time for families right across the country".
ALONE, the organisation that supports older people to age at home, said last night that "hard decisions were being made in homes where the choice between heating or eating is real while others opt to go to bed as the solution to not turning on the heat".
They urged anyone struggling to cope to contact its helpline on 0818 222 024.
ALONE chief Seán Moynihan said: "We need across departmental intervention to provide protection for the basic needs of older people in our society."
Announcing yet further price increases, Done Deal said the price of used cars continues to grow at unprecedented levels in 2022. In the first three months of 2022, used car prices increased by 7.9% quarter on quarter, the tenth consecutive quarter of increases seen in its dataset.
According to the latest Daft.ie report, house prices are still continuing to rise.
The Government's €200 credit to help families with soaring electricity costs will be taken off this month's bills.
But some may not see that deduction until May or June, as it depends on a household's billing cycle and electricity supplier.
Electric Ireland, the State-owned power company is Ireland's largest with 1.1 million electricity customers - 47% of the market - and 146,000 gas customers, just over a fifth of the market.
It announced last week it was increasing electricity prices by more than 23% and gas prices by almost 25% from May 1. In less than a year, electricity prices under Electric Ireland have risen by €508, while gas prices have increased by €338.
It claimed it had delayed the increase for as long as possible but wholesale price pressures forced it to raise its retail prices.
Company director Marguerite Sayers said: "We are acutely aware that the rising cost of living is causing difficulty for households across the country. We delayed the increase as long as we could in the hope that wholesale prices would drop back to early 2021 levels, but this has not happened."
Meanwhile, the Government is facing a carbon tax revolt growing as it plans to end the reduced 9% VAT rate for hospitality threatening to further fuel inflation.
