Default Loud tapping noise....

Hi. The 2002 TA had a loud tapping noise that at first I thought was fuel injectors.(sounds like the injectors on my Town Car v8). This afternoon I got a bit concerned and warmed up the trans am. Got fresh gas, and drove it hard for a few miles. When I came home, the tapping noise was gone. Was it just sticky injectors? The car has been in storage for years and only has 20k on the odometer. Dealer did an oil change, filled all fluids. This is my first LT!, so I don't know much about them. any input is appreciated.
Mark.

The owners manual says it's it's an LT1 V8.

"A "2002 Trans Am LT1" refers to a 2002 Pontiac Firebird Trans Am model which is equipped with the LT1 engine, a powerful V8 engine that was used in the later years of the Firebird production run; known for its performance capabilities, this car is often considered a classic muscle car with a sporty design and reputation for good handling. "

"Key points about the 2002 Trans Am LT1:
  • Engine: The LT1 engine is a 5.7L V8 producing around 320 horsepower.
  • Performance: This model is known for its quick acceleration and strong power delivery.
  • WS6 Package: Many 2002 Trans Ams with the LT1 engine were equipped with the "WS6" performance package, which included additional aerodynamic features and suspension upgrades for improved handling.
  • Potential Issues: While the LT1 engine is generally reliable, some common concerns include potential issues with the Optispark ignition system, which can be sensitive to moisture.

It's a LS1. Run some Seafoam or Barryman's in the gas tank and it will clean the injectors.

I'll believe the owners manual, and the GM website for parts, listing the LS! as an engine choice for my 2002 year. LOL!.

From Road & Track.....
"The LS family of V8s are GM's gift to those seeking affordable, reliable performance, and that was true 20 years ago. For 1998, Pontiac equipped the Trans Am with a 305-hp version of the LS1, and immediately, a new benchmark for cheap speed was established. As Motorweek notes in this 1998 review, the Trans Am offered "Corvette performance for a minivan price."The LS1 also helped the Trans Am leave the rival Ford Mustang in the dust. If you wanted a 1998 Mustang with as much power as a Trans Am, you'd have to step up to a Cobra—the base 4.6-liter V8 only offered 225 hp. And even then, the Cobra couldn't match the Trans Am's 335 lb-ft of torque.

Motorweek recorded a 5.5-second 0-60 mph run and a 14-second quarter-mile in a 1998 Trans Am WS6. Impressive, especially when you consider that pricing for the Trans Am started at $26,500, which is around $40,000 in today's money."

Done and done.
