Why does it pull back while driving?

I changed the distribuitor, spark plugs, plug wires, distribuitor cap, ignition rotor, TPS sensor, and the map sensor. I checked the fuel pressure, it's 55-60 psi. I connected the scanner machine, but it didn't give me any codes. the check engine light is not on. it still has the same problem.

Why does my 2.5 GMC sonoma truck skips or misses?

Worn timing belt or bad map sensor, weak ignition coil, worn distributor gear (usually starts hard with that) Leaking manifold gaskets all possible causes. Start with a new coil, spray starting fluid around manifold gasket while running, if it revs up in any certain spots, manifold leaking (intake only test), check vacuum lines for cracks and leaks,(MAP) replace sensor. Over 75,000 miles probably timing belt, recommended change interval is 60,000 miles.

Loss of power

Do you know how check if every cilinder is working? with the engine in idle, go to the distribuitor cap and carefully unplug one at the time, every cilinder spark plug wire,in the cilinder you dont see a diference in rpm variation, that cilinder is not working, replace spark plug, if you see spark jumping fron the distribuitor cap torch the spark plug wire, another cause to a cilinder fail could be a loss of compression in one or more cilinder

Hi,you can run a fuel presure test to see if the fuel pump is working properly, you can also run a timing chain text ,this is a little complicated but you may be able to do it , take the distribuitor cap off,with a ratchet turn the crankshaft back and faward,if the rotor takes to long to move the chain is worn out,this can cause loss of power, I hope this will help.........
