1999 Pontiac Grand AM SE engine hesitating
1999 Pontiac Grand AM SE starts fine, but has a miss to it, will only go to 10- 15 miles per hour

As though ambushed by the Extreme Makover crew, the 1999 Pontiac Grand Am gets a new body, more Grand Prix-like styling, and a whole new set of trim styles for its fifth generation. Though shorter in overall length, a longer wheelbase and pushed-out wheels help provide a sturdier, more stable ride. Bigger front brakes add extra safety, and an all-new stiffer chassis with four-wheel independent suspension guarantees less highway shudder than previous models. New ribbed lower cladding and body-colored moldings beef up the attitude and sporty styling. The interior has also been reworked, with a whole new dash design and seats that are set higher for better comfort and visibility. Still available as a coupe or sedan, the 1999 Grand Am adds some new trim names, whose differences lie mainly in their standard feature offerings. SE and SE1 share the old 2.4-liter, Twin Cam, 150-hp I4 engine. The SE2, GT, and GT1 are powered by a new 3.4-liter, 170-hp V6. Only a 4-speed automatic transmission is available in 1999. Standard across the line are ABS brakes, traction control, power locks, tachometer, and daytime running lights. A rear spoiler, cruise control, and power windows are added as you go up the line. The looks and style of the 1999 Pontiac Grand Am earn praise from owners, who like the new engine power and improved acceleration response. Traction control has also been improved. Unfortunately, the Grand Am is still saddled with a long list of repair problems, including the quickly worn brake pads and rotors, and a new problem with window regulators. Overall build quality is heavily criticized. More minor complaints focus on the poor cupholder placement and a not particularly roomy interior.

1999 Pontiac Grand Am GT that shut off randomly while driving, was filled to full shortly before shutoff. Spark at each plug/ignition coil. Fuel pump primes audibly and i got splashed a little while testing spark on one of the plugs so I believe the engine is getting fuel. Fuel relay is good. Saw online that an ac fuse can cause problems but all fuses test and look good. Also saw online that security system can cause problems and the security light on the dash is solid(people who have this issue typically have a flashing security light), tried to reset by leaving in ACC position for ten minutes, turned off, turned back to ACC for ten minutes, turned off, and tried to start again to no avail. OBDII reading shows no stored codes and the MAF is reading flow, RPM on the dash is still but OBDII shows rpm info going to the ECM. The car sounds like its on the verge of starting when at 5% throttle. Starting fluid in the airbox intake has no effect. Running out of Ideas and don't have the money to shotgun parts without certainty that it will fix the problem.
ac work for about a week after putting 2cANS OF R134 AND STOP LEAK IN AC UNIT
I have a 99 pontiac grand am se 3.4L V6. The issue is that it starts and idles fine but as soon as I go to accelerate it just shuts off. It did have overheating issues but right after I fixed those it started doing this. I replaced the cam position sensor and also the engine coolant temp sensor and it didnt help. I was thinking of replacing the ignition coil packs and housi g but not sure if that would fix it. There are no check engine lights or stored codes .
I have a coolant leak on my pontiac Grand Am. I checked the hoses from the reservoir and the radiator but I can’t see where it could be leaking from those. Looking underneath it looks like it dripped down the front part of the trans pan and is dripping from there. Any other spots it could be leaking from? Or is there a hidden hose somewhere?
