n [8 fuel injection good used meters they measure the amount of air coming into engine so the brain can calculate the correct amount of fuel to use bosch currently lists over 25 different part numbers call us with yours save these relays supply electricity to your fuel pump or pumps this little device will keep you from starting if it malfunctions we have new and recycled from $15.00 ea get the part number off the relay so we re sure we get you the right one [9 relay fuel pump works like keeping your foot on the gas to let it warm up when you step on the gas you are actually stepping on the air the accelerator cable only opens the air valves throttle valves so pumping the gas before you turn over the car does nothing but give you exercise to make the car race with your foot off the gas you have to give it some air the auxiliary air valve is just a u -shaped hose around the throttle valves to give it extra air vw® put a rotary valve in the line that times out and closes after the car warms up so it won t race simple they clog with junk and burn out our recycled ones are the best value all vw® thru `81 #sn11520 new 89.95 #sn11521 recycled 30.00 all vw® `82-84 #sn9178 new 99.95

incorporate an electronic throttle position sensor sometimes these go bad call us we ve got good recycled throttle bodies in stock [10 cold start valve sometimes called the 5th injector this thing sprays a squirt of gas 2 to 20 seconds to get the car to kick over and start the gas does not go through the fuel distributor so sometimes the car will start and run for 5 or 10 seconds then start again and again and again but won t run for more than 20 seconds it s running on gas from the 5th injector your problem is that the fuel distributor is clogged the cold start valve has constant fuel under pressure and the electric wire from the thermo time switch is just telling it to fire if you put 12 volts to the cold start valve and it does not fire and you have fuel pressure replace it cold start valve most vw® `77-89 #sn11516 new 115.95 #sn33146 recycled 50.00 call for other applications [15 the oxygen sensor or as it s more uncommonly known the lambda sensor sniffs the oxygen content in the exhaust gas and signals the fuel injection to enrich or lean depending on the situation these devices do require periodic replacement usually every 30,000 miles we stock a wide variety for all vws® irregular idle 49.95 each [16 the frequency valve from count the prungs is a little pump to enrich the fuel/air mixture it s only found on cars from 1981-on it works in conjunction with the oxygen sensor and adjusts the amount of fuel our recycled part works fine bosch lists 10 different part numbers our recycled valve should work great for years [11 the thermo switch has a timer and bi-metallic element it is heated by the engine water and depending upon how hot it is it allows electricity to flow from 2 to 20 seconds to open the cold start valve it should time out jumper it to check the system replace if defective our recycled thermo switches work perfect all vws® 1977-87 #sn3047 .84.95 #sn33982 rec .25.00 [12 warm-up regulator this acts like a choke it makes the car run richer it picks up heat from the block and from an internal bi-metallic heater what it does is apply fuel pressure to the top of the fuel distributor pin pushing it down making it run rich if the car starts but runs poor until it warms up it could be this `77-83 #sn14269 reman 139.95 #sn30152 recycled 75.00 `84-87 #sn14416 reman 139.00 #sn9491 recycled 89.00 is used to control idle speed on later

`85-93 vws® with cis-e or cis-motronic injection this electromagnetic device makes small adjustments to the fuel mixture by altering pressure to the lower half of the fuel distributor using signals form the o2 sensor coolant temp sensors and a few other sensors the f i brain tells the differential pressure regulator to enrich or lean out the fuel mixture if yours is bad the car will run roughly
