Just had broken timing belt fixed but mow it's hard to get up to speed it eventually will but starting off you can press it to the floor and it'll bog down shakes and I hear a light tic sounds like a stun gun sound but slower check engine light flashes and takes a high rpm for gears to change any ideas anyone please help

What kind of mechanic did the work?
Which X and engine are you dealing with here?
You might try adjusting the distributor to see if the timing is off.

Did it break while running? If so, it is an interference engine, which could mean bent valves.

how deep is the sound? light tic tic tic or deep tock tock tock like noise? as others stated above we need a bit more info what year and engine? i am going to assume 1st gen 3.3 n/a as thats the most common with timing belt issues, it is an interference engine, and from what you are describing you have broken something or the new belt wasnt set in time 100% right its very easy to bend a valve when the timing belt breaks on the 3.3 this will cause loss of power and compression in the piston as the valve cant close properly. it can aslo induce a noise such as you are hearing

Did one of the cam shafts rotate out of position when you took the timing belt off? This is very common and all you have to do is turn it back to the correct position, but you must turn it in the opposite direction that it moved. Usually it will turn clockwise. If it rotated clockwise then you have to turn it BACKWARDS (counter clockwise) to it's correct position. If you turned it forwards (clockwise) instead then the valve timing on that camshaft will be out by 180 degrees and it's not going to run right. Likewise, if it rotated out of position in the other direction you would have to follow the reverse procedure and turn it clockwise.

So recap. If it turned to the right, turn it back to the left. If it turned to the left, turn it back to the right.

In addition to the above, since the belt broke it is entirely possible that one of the cam shafts had an extra rotation with the same result as stated above. It is easy to assume that because all of the marks line, the timing is correct, but the only way to really tell for sure that I know of is to take the valve covers off and check the valve positions as you rotate the crankshaft manually.

Another possibility is that the new belt was not tensioned correctly and has jumped a tooth or two, throwing the timing out, though my money is on one of the camshafts being 180 off. It would mean that you are basically running on 3 cylinders. I wouldn't run it until you check it out. If you get detonation at the wrong time you could do some major damage.

I've only worked with my '00 3.3, but my camshaft gears have impressed marks on them that would clearly indicate whether the cam was out of sync, even 180 degrees. For mine, its way easier to get to the timing belt area than to pull the manifold to get into the valve covers. The OP hasn't yet indicated which X they're describing...

I can't imagine a reputable mechanic would do all this work and return the vehicle to the customer with such an obvious power issue!

Any update on this situation?
Are compression test of each cylinder would tell you a lot before any further money is spent
