SOURCE: I Have a 2002 blazer that starts but motor dies, surges when accelerating

If this engine is a VORTEC then you may have a problem with the internal fuel system. Under the top plenum there is a fuel reg and poppet valves that inject fuel into the cylinders. Sometimes the tubes that run fuel from the reg to the valves can leak and cause your problem. This cannot be found with pressure check because this occurrs after the reg. PS fuel mileage will go down. Let me know if this helps.Moe

SOURCE: 1989 GMC 2500 5.7L - engine surges and stalls at idle. Loses power at cruising speed.

Wow you have replaced a lot of stuff. Lets go back to the Fuel pump. When you replaced it did you replace the hose between the pump and the sending unit. These are common for splitting. Have you hooked up a fuel pressure gauge to check what pressure you have? It should be real close to 13 psi and should raise to at least 18 or 19 when you pinch off the return line.

SOURCE: I have a 1987 924s porsche..i had an intake leak

If you have spark and gas it should at least fire unless you don't have any compression. I would make sure that you have spark on all cylinders at the spark plugs.

Missing fire on a cylinder how to diagnose which one ?


With a scan tool the ECU should tell you what cylinders are registering missfires. Easiest way to tell what cylinder is not firing is with a laser pyometer. You can point it at the exhaust manifold at each cylinder and find what ones are cool. Also I would suggest looking for a vacuum leak after the mass meter. Either in the air inlet pipe or around the intake manifold.

Check engine compression and compare. then test running engine compression most engines have about 130-170 cranking compression and about 90-110 running compression. OR bring that cylinder to its Top Dead Center compression stroke apply air to the cylinder and check to see where the air is going open throttle plate bad intake valve, from exhaust pipe bad exhaust valve, from oil cap piston rings.

"All cylinders have 120 psi compression." I would be seriously concerned about this. Typically, an engine's compression should be much higher e.g. 180 psi or more. Could mud have gotten into the exhaust system causing restrictive back pressure?

CAR SURGES WHEN YOU ACCELERATE IN OVER DRIVE.


It may be the MAF sensor. In needs to be cleaned or replaced. Located on the throttle body, under the engine cover. Might need special anti-tamper Torx sockets to remove. 2 bolts. One wire connector.

I had to replace mine on 2002 3800 V6. Bucked and shook on moderate to hard acceleration at about 3500-4000 rpms.
