Fuel Injection Problems of Chevrolet Tahoe

Bought from new 99 Tahoe. Has had 2 runaway over speed events. The 2nd was yesterday. It has been having also, loss of power at time when first starting off. It goes away quickly, usually in few seconds. Hear at least one exhaust popping noise during event. Never looses power during long highway travel. Both times the runaway acceleration was after a hard acceleration. Goes into bauck ( loss of power) & then into full acceleration! last runaway required 3 key off shutdowns to relieve. Neutral caused it to rev to 5000 rpm. Brakes seem to control run away a bit at 40mph, but not down hill! we never use cruse control & it was in off position. Hard to steer of course with engine off at 40+ mph! suspect fuel injection system. Was in drive position at occurrence. First occurrence was about a month previous. It was controlled by full braking stop then. It was then only at slow speed to start. A less experienced driver on the steep hill I came up on during run away could have been killed into trees on side of hill. Ex nasa engr with only carburetter knowledge!.

The contact owns a 1999 Chevrolet Tahoe. The rear end caught on fire. Vehicle was making a noise so she pulled over, and the person behind consumer was flagging her down because the vehicle was on fire. She smelled fuel coming from the vehicle.

The abs light kept coming on. Could hear clicking in the brakes. Contacted the dealer, they said to bring the vehicle in. Took the vehicle to dealer, and they fixed the vehicle, but had to pay out of pocket. Took the vehicle in on March 30, 2005. They replaced the number two injector.

I have a 2000 Tahoe Chevrolet ltd. Since 3/04 it has failed to start about 7 or 8 times. It usually occurs in the morning when I'm leaving for work. Once we were on our way to the hospital for my 14 month old's broken arm. It turns over but will not start. I have had it checked several times. When the shop checks it several hours later, it starts. They have replaced several items. None of which have worked. They told me that they couldn't find anything wrong with it and they were just replacing things that might be causing the problem. It's very frustrating.

On 2-11-03, the California epa announced that general motors has been required to extend the fuel injector warranty on '96-'01 model year light trucks, suvs, trucks & vans to 10 years/200,000 miles. "malfunctioning fuel injection systems (scpi) cause significant increases in air pollution". Gm will fix the problem at no cost to the vehicle owners. The fuel systems were replaced with the new mfi units. Gm settled with the California epa to avoid a threat of a nationwide recall. I own a vehicle that falls into this category but do not live in California. I contacted local dealerships as well as the Chevrolet customer care center for assistance and was told that only vehicles in California were eligible to be repaired. All affected vehicles manufactured by gm with the defective scpi fuel system should be treated in the same manner as this is not only an issue for vehicles driven in California. The fuel injector (oem part number 17091432). Replacing plugs, wires, distributor cap & rotor, cleaning injector & induction systems does not eliminate the basic problem which is a defective scpi fuel system. . Read more...
